Every term on this site, in plain English.
The explanations behind every number, tooltip and footnote on this site, collected in one searchable place. Nothing here is simplified to the point of being wrong: where a threshold is a commonly-used convention rather than a hard rule (or an invented one, not published by the investor it's attributed to), that's said plainly.

Valuation
P/E Ratio (Price/Earnings) #
Share price divided by earnings per share: how much you're paying per dollar of annual profit. This site uses trailing twelve months (TTM), the actual last four reported quarters, not an analyst forecast. The 8-filter screen requires a P/E under 25. A ceiling on how much you're paying, regardless of the growth story. Read what a good P/E ratio is.
PEG Ratio #
P/E divided by the earnings growth rate: Peter Lynch's "growth at a reasonable price" test, where a PEG of 1 is his fair-value line. This site uses two bars: the Lynch checklist wants under 1, and the 8-filter screen allows up to 1.5. When a stock's data provider doesn't report a PEG directly, this site estimates one as trailing P/E ÷ 5-year EPS growth (only when growth is positive), marked with a † wherever that happens, never shown as identical to a directly-reported number. See every stock ranked by PEG, lowest or highest first.
Price/Book (P/B) #
Share price divided by book value (assets minus liabilities) per share. Useful for capital-heavy businesses; less meaningful for asset-light software or service companies. The 8-filter screen requires under 8.
Price/Sales (P/S) #
Share price divided by revenue per share. Doesn't care whether the company is actually profitable; pair it with a margin or earnings metric, don't read it alone. The 8-filter screen requires under 7.
Price/FCF #
Share price divided by free cash flow per share. Whether a growth story is backed by real cash generation, not just accounting profit that can be shaped by non-cash items.
FCF Yield #
Free cash flow per share divided by price: Price/FCF turned upside down, so a higher yield means cheaper. Many value investors weight it over P/E because free cash flow is real money moving through the business and harder to flatter with accounting choices. Banks, insurers, real-estate and utility companies are left out, because a standard cash-flow model doesn't fit them. See every stock ranked by FCF yield.
Intrinsic Value (DCF) #
A discounted-cash-flow estimate of what a business is worth today: project its free cash flow forward using a growth rate, discount each future year back to today's dollars using a discount rate, and add a terminal value for everything beyond the projection window. In the Intrinsic Value Calculator every input is yours to set. Wherever this site values many stocks at once (the stock card, the Margin of Safety Explorer, the shortlist) it applies one neutral set of assumptions to every stock, never one tailored per company: 8% growth fading to 2.5%, a 10% discount rate and 2.5% terminal growth over 10 years. Read what growth a share price implies.
Margin of Safety #
Benjamin Graham's central idea: only buy when price sits well below a computed intrinsic value, so the gap is your cushion against being wrong about the future. Computed here as (intrinsic value − price) ÷ intrinsic value, using the neutral assumptions above. A margin of 25% or more is what this site calls a Graham margin. A starting point for research, not a buy signal. See every stock ranked by margin of safety. See the margin of safety method. Read what a margin of safety is.
Overvalued / Value Trap #
Overvalued means today's price sits above the computed intrinsic value, the opposite of a margin of safety. A value trap is a different, more specific warning: a stock that looks cheap on that same DCF (price below intrinsic value) while failing 3 or more of the 8 baseline filters. Cheap and structurally weak isn't a bargain, usually it's cheap for a reason. See Overvalued & Value Traps. Read how to check if a stock is a value trap.
Discount Rate #
How much less a dollar received in the future is worth to you today. Turn it up and you're demanding more compensation for waiting and for risk, which makes every future dollar worth less right now. The single assumption a DCF is most sensitive to. See the Discount Rate Calculator.
CAPM (Capital Asset Pricing Model) #
A textbook formula for a stock's cost of equity: risk-free rate + beta × equity risk premium. A reference point for choosing a discount rate, not the only valid answer.
Beta #
How volatile a stock's price has historically been versus the overall market. Above 1 means historically more volatile than the market, below 1 means less. A rough, widely-used proxy for risk, not a complete picture of it.
Risk-Free Rate #
The 10-year US Treasury yield: roughly what you could earn with no meaningful risk of default. The baseline every other required return gets measured against.
Terminal Value / Terminal Growth Rate #
A DCF can't project cash flows forever, so after the projection window it assumes the business grows at a slow, steady "terminal" rate forever after and capitalizes that into one lump-sum value today. Small changes to this rate can move the total valuation a lot.
Owner Earnings #
Warren Buffett's own term (from his 1986 Berkshire Hathaway shareholder letter) for the real cash a business could pay out to its owners after running and reinvesting in itself, harder to distort than accounting net income.
Growth & Quality
EPS Growth #
How fast earnings per share have grown, either year-over-year or annualized over a multi-year window. The 8-filter screen uses the latest quarter against the same quarter a year earlier and asks only that it isn't worse than −5%. The stock card shows both a recent (5-year) pace and a full-history pace, so you can see whether growth is accelerating or slowing, not just one snapshot number.
ROE (Return on Equity) #
Profit generated per dollar shareholders have invested in the business, over the trailing twelve months. A read on how efficiently a company turns equity into profit. The Capital-Light Compounders page asks the related question: how much capital each extra dollar of profit needed.
Debt/Equity #
Total debt divided by shareholders' equity: how much a company has borrowed relative to what its owners actually own. Lower generally means less risk if the economy turns, though "normal" varies a lot by industry (a bank or utility carries far more debt than a software company as a matter of course).
Interest Coverage #
How many times over a company could pay its annual interest expense out of operating profit. A safety cushion on its debt: higher is safer.
Pretax Margin / Net Margin #
Profit (before or after tax) as a percentage of revenue: a read on pricing power and cost discipline. Higher generally means a business keeps more of every dollar it brings in.
Free Cash Flow (FCF) #
Operating cash flow minus capital expenditures: the real, spendable cash a business generates after running itself and paying for the equipment/property it needs to keep running. The fuel for every DCF on this site.
Operating Profit (EBIT) #
Profit before interest and tax: what the business itself earns from its operations, before how it is financed or taxed. The profit measure behind the Altman Z″-Score and the Capital-Light Compounders test, because it compares companies with different debt loads and tax rates fairly.
Beneish M-Score #
An eight-ratio model (Messod Beneish, 1999) that compares this year's books with last year's to estimate how likely a company is to be flattering its earnings. Above −1.78 is the flag line and below −2.22 looks clean. It also trips on fast growers and companies that just made an acquisition, so treat a flag as a reason to read the filing, not a verdict. Computed for every tracked stock in the Earnings Quality Screener. See how earnings quality is graded.
Accruals Ratio #
(Net income − operating cash flow) ÷ average total assets, the measure Richard Sloan (1996) used to show that profit built on accounting accruals fades faster than profit backed by cash. Positive means profit ran ahead of cash: up to 5% is normal, over 10% is a flag. Negative means cash beat profit. The Earnings Quality page grades every tracked stock on it.
Cash Conversion #
Operating cash flow divided by net income, here over up to three years. 100% means every dollar of reported profit arrived as cash; well below that, profit is piling up as receivables, inventory or non-cash gains. It has no meaning while a company is losing money. The Earnings Quality page grades every tracked stock on it.
Stock-Based Compensation (SBC) #
Pay handed to employees in shares or options instead of cash. Profit and cash-flow figures often add it back as a non-cash cost, but it still costs owners: it dilutes their slice of the company or forces buybacks just to stand still. The Stock-Comp Haircut shows free cash flow after it.
Market Capitalization #
Share price × total shares outstanding: the total value the market currently places on a company's equity. The 8-filter screen starts at $25 billion.
Altman Z″-Score #
Edward Altman's published bankruptcy-risk formula in its 1995 version for non-manufacturers, which drops the sales ratio that makes his original 1968 score misleading for software and service companies. It combines four ratios (working capital, retained earnings, operating profit and book equity, each against total assets or liabilities). Above 2.6 is Altman's "safe" zone, 1.1–2.6 the "grey" zone and below 1.1 the "distress" zone. The thresholds are his, not this site's. Banks, insurers, real-estate and utility companies are left out. A low score is a question about the balance sheet, not a bankruptcy forecast. See the Altman Z″-Score Screener. Read how to tell if a company might go bankrupt.
Capital-Light Business #
A business that grows its profit without needing much new capital. Buffett's own example is See's Candies, whose profit rose from under $5 million to $82 million on only $32 million of added capital. For every tracked stock this site measures how many dollars of capital (operating working capital plus net property, plant and equipment, with goodwill added in the "full cost" view) were added per $1 of added operating profit, and the pre-tax return on that capital. Research, brands and advertising never show up as capital, so software and consumer-brand companies look lighter than they are. See the Capital-Light Compounders. Read the See's Candies test.
Dividends & Payouts
Dividend Yield (TTM) #
Trailing-twelve-month dividends paid per share, divided by the current price. This site shows TTM because its free-tier data providers don't expose a true 5-year average; that limitation is stated on every page that shows it. See every dividend payer ranked by yield. For the formula and what it means once you reinvest, read the dividend calculator guide.
Payout Ratio #
Dividends paid as a percentage of earnings. Above 100% means a company paid out more than it earned over the trailing year, not always a red flag (REITs are conventionally measured against FFO instead), but worth a second look. The Sustainable Dividend Screener checks the payout against cash flow as well as earnings. Read how to calculate the payout ratio.
Cash-Flow Payout Ratio #
Dividend per share divided by free cash flow per share. Over 100% means the company is paying out more cash than it actually generates, so the dividend is being funded by debt or cash reserves. The core check of the Sustainable Dividend Screener, because cash is harder to flatter than accounting earnings.
Yield Trap / Sustainable Dividend #
A very high yield can mean a strong business paying out real cash, or a falling share price and a dividend about to be cut. The Sustainable Dividend Screener runs six checks: cash-flow payout, negative free cash flow, earnings payout, high leverage, weak interest coverage and declining revenue. A payer with 0 or 1 flags is sustainable; with 3 or more it is a yield trap; exactly 2 is a genuine gray area. Passing is not a promise, and failing is not a verdict. Read how to find safe high-dividend stocks.
DRIP (Dividend Reinvestment Plan) #
Using each dividend to buy more shares of the same stock instead of taking the cash, so the next dividend is paid on a larger holding. The DRIP Calculator projects reinvesting every dividend against taking them as cash, plus a theoretical tax-free case to show how much of your compounding taxes erode; every assumption is one you set. The dividend calculator guide walks through the inputs step by step.
Buyback Yield #
Cash spent repurchasing the company's own shares over a year, divided by market cap. A buyback at a very high price destroys value, so a high buyback yield is not a virtue by itself; it is one of the three parts of shareholder yield. The Shareholder Yield page ranks every tracked stock on it, net of the stock issued to staff.
Risk & Safety
Short Interest / % of Float / Days to Cover #
How many shares are currently sold short, as reported to FINRA twice a month. % of Float scales that against actual tradable shares; Days to Cover estimates how many days of average trading volume it would take short-sellers to buy back their positions. Real, reported numbers, not a squeeze prediction.
Munger's Inversion Check #
"Invert, always invert": Charlie Munger's habit of looking for reasons to hesitate instead of reasons to buy. This site's version is a real tally of specific flags (thin margin of safety even in a bull case, elevated short interest, several failed fundamental filters, momentum without value support, rising leverage), never a single synthesized "risk score." A stock with no flag tripped is called "Munger-clean."
52-Week Range #
The highest and lowest closing price over the trailing year, with today's price plotted between them, a quick read on where a stock sits within its own recent history. See the stocks closest to their 52-week low.
Falling Knife #
A stock that is falling for a reason, not just a temporary dip. The Mean Reversion Screener checks seven fundamental red flags (heavy debt, a thin cash cushion, losses, weak interest coverage, shrinking sales, a deep fall from the 52-week high, and heavy insider selling), several of them measured against the stock's own sector, and shows how many are lit. Three or more is high risk.
Drawdown #
How far a price (or a portfolio) has fallen from its previous peak, usually measured to the lowest point afterward. The Stress Test on the home page replays today's picks through four past crashes (the dot-com bust, 2008, COVID and the 2022 bear market) from the S&P 500's peak to its bottom. Read it with hindsight in mind: every one of today's picks survived to be there, which flatters the result. The Portfolio Doctor replays your own holdings through past crashes to show how deep yours would have fallen.
Why some sectors are excluded from the DCF tools #
Banks, insurers, financial-services, real-estate, and utility companies are left out of every free-cash-flow DCF ranking on this site (Margin of Safety Explorer, Overvalued & Value Traps, the shortlist, the Munger bull-case check). A standard FCF model doesn't fit how these businesses report cash flow: a bank's operating cash flow swings with deposit and loan volume, a REIT is conventionally measured against FFO, and a regulated utility reinvests nearly all its operating cash into capex even when perfectly healthy. Including them would rank the model's blind spots, not the businesses.
Technical Analysis
Mean Reversion #
The idea that a price stretched far from its own average tends to snap back toward it, the opposite bet from a breakout strategy, which assumes a price breaking out of a range keeps moving in that direction. Measured here with five real signals: RSI, distance below the 20-day SMA, Bollinger Band position, a heavy-volume selling spike and 52-week-low proximity, not a single indicator alone. A screen finds stocks under selling pressure, not stocks that will bounce. See the Mean Reversion Screener for real signals across the tracked universe.
SMA (Simple Moving Average) #
The average closing price over the trailing N days (commonly 50 or 200). A slower, smoother read on trend than the daily price itself; price crossing above or below its own moving average is a commonly-watched (though imperfect) trend signal. The 8-filter screen asks that price sit within 12% of both its 50-day and 200-day average.
RSI (Relative Strength Index) #
A momentum oscillator from 0 to 100 measuring how fast and how much a price has moved recently. Below 30 is conventionally read as "oversold," above 70 as "overbought", a momentum reading, not a valuation judgment. See real RSI14 readings across the tracked universe on the Mean Reversion Screener. Read what RSI below 30 means.
Bollinger Bands #
A band drawn a set distance (in standard deviations) above and below a moving average, widening and narrowing with volatility. A close outside the band is a statistically unusual move, not automatically a buy or sell signal. Used as one of five real signals on the Mean Reversion Screener.
ATR (Average True Range) #
The average size of a stock's daily price range over the last 14 periods, a measure of how much it normally moves in a day. The Mean Reversion Screener draws ATR channels on its chart and can place a stop-loss a chosen multiple of ATR below your entry, so the stop sits outside normal noise.
Support & Resistance #
Price levels where a stock has repeatedly turned: support below it, resistance above. On the Technical Analysis tool they are computed from real swing highs and lows in the closing-price history (a 10-trading-day pivot window), grouping turns within 2.5% of each other into one level and ranking by how many separate times price actually turned there. Closing prices only, so a level can miss an intraday wick.
Position Sizing / Stop-Loss #
Deciding how many shares to buy by the loss you are willing to take, not by the price. Shares = dollars you will risk ÷ (entry price − stop-loss price). A stop-loss is the price at which you commit to exit if you are wrong. The Mean Reversion Screener's Swing Position & Risk panel does the arithmetic with your own capital and risk percentage; the output is arithmetic, not advice. The Mean Reversion page has a swing position and risk calculator, and the Portfolio Doctor shows how concentrated your holdings already are.
Macro & Market Gauges
Yield Curve / Treasury Spread #
The difference between longer- and shorter-term Treasury yields (commonly 10-year minus 3-month, or 10-year minus 2-year). A negative spread (inversion) has preceded every US recession since 1970 and is the NY Fed's own preferred recession indicator, though the lead time varies a lot and it has occasionally been a false alarm. Tracked live, alongside 25 other real indicators, on the Crash Indicator. Read whether an inverted yield curve predicts a recession.
Credit Spread #
The extra yield lenders demand on riskier corporate debt over safe Treasuries of the same maturity. Widening spreads mean lenders are pricing in more risk, a classic "risk-off" warning. Both investment-grade and high-yield spreads are shown live on the Crash Indicator.
Fed Funds Rate #
The interest rate the Federal Reserve targets for overnight lending between banks, the Fed's primary lever for tightening or loosening financial conditions economy-wide. The Dollar vs. Euro page sets it beside the ECB's rate and the inflation-adjusted real rate.
CPI (Consumer Price Index) #
A measure of how much prices for a broad basket of consumer goods and services have changed. The headline inflation number that drives Fed rate decisions and real (inflation-adjusted) equity returns. The Dollar vs. Euro page uses it to turn nominal interest rates into real ones.
M2 Money Supply #
The amount of money in the economy counted broadly: cash, checking and savings deposits. Stock markets run on liquidity, so how fast M2 is growing (and what the central bank's balance sheet is doing) is a context gauge. The Dollar vs. Euro page sets the US figures beside the euro area's, including the M3 measure the Fed stopped publishing in 2006.
Buffett Indicator #
Total stock market value compared with the size of the economy (GDP). Warren Buffett once called it "probably the best single measure of where valuations stand." Readings above roughly 150–200% have historically preceded periods of poor forward returns. This site computes a proxy from its own tracked universe, labelled as one on the Crash Indicator, not the full Wilshire-5000 figure. Read what the Buffett Indicator is.
Shiller CAPE #
Price divided by the average of the last ten years of inflation-adjusted earnings, Robert Shiller's way of smoothing out the business cycle. A high CAPE says little about next month but has gone with weak returns over the following decade. It is one of the market-wide gauges the Sector Valuation Map then breaks down by sector. Read what the Shiller CAPE ratio is.
Forward P/E #
Price divided by next-twelve-months analyst-estimated earnings, as opposed to the trailing P/E used for the screener. The Crash Indicator shows a market-cap-weighted version across the tracked universe; a broad forward P/E well above 20–22×, especially while earnings growth slows, has flagged stretched valuations.
Sahm Rule #
A recession signal built from the unemployment rate: it compares the 3-month average with its lowest point of the past 12 months. Historically, every time that gap has reached 0.50 percentage points or more the US was already in a recession. It confirms a downturn rather than predicting one. Read what the Sahm rule is.
VIX (Volatility Index) #
The market's expected 30-day volatility of the S&P 500, often called the fear gauge. The Crash Indicator compares it with the 3-month volatility index: normally the 30-day reading is lower, and when it flips above the 3-month reading it signals acute, immediate stress. A VIX below 12 signals extreme complacency, above 30 a real volatility spike.
Market Breadth #
How many stocks are taking part in a move. Here it is the share of tracked stocks trading above their own 200-day average. A shrinking share while the headline indexes sit near highs is the classic "fewer stocks carrying the market" warning sign.
Margin Debt #
Money investors have borrowed against their stock portfolios (FINRA's "debit balances in margin accounts"). Fast growth means leverage is building, and forced selling to meet margin calls makes falls steeper.
Filings & Insiders
Form 13F #
The quarterly filing in which a fund manager with more than $100 million in US-listed stocks lists every position to the SEC. It describes the last day of a quarter and arrives up to 45 days later, so it is always out of date. It shows long US stock positions only: no short positions, cash, bonds, non-US stocks, cost basis or trade dates. The Superinvestors page is built from these filings. Read how to read a 13F.
Schedule 13D / 13G #
Filings that disclose when an owner crosses 5% of a company's shares. A 13D is for owners that may seek to influence the company; a 13G is the shorter form for passive holders. They run on a shorter clock than the quarterly 13F, so they usually arrive fresher.
Form 4 / Insider Buying #
The filing in which a company's officers, directors and large owners report their own stock trades within two business days. This site counts only open-market purchases (not option exercises, stock awards or gifts) and ranks by how many different insiders bought. Insiders sell for many reasons (taxes, diversification, scheduled plans) but buy for one, so a purchase is the more informative direction. See the Insider Buying Tracker.
"Since Quarter-End" #
On the Superinvestors page, how a stock has done since the last day of the quarter the filing covers: today's price against the price implied by the filing. It is what a follower would have earned from the moment the book became knowable, not what the investor earned, and it ignores dividends and any trades during the quarter.
Site Tools & Terms
The 8 Baseline Filters / "Passed All 8" #
The fixed, mechanical bar the screener applies every week: market cap above $25B, trailing P/E under 25, PEG under 1.5, price/book under 8, price/sales under 7, quarterly EPS growth above −5%, and price within 12% of both its 50-day and 200-day moving average. A stock that clears all eight in the same run is marked "Passed all 8 filters." The bar doesn't change from week to week.
Passes Everything #
A stock that clears everything this site checks, not just the 8 baseline filters: it also comes up clean on Munger's Inversion Check and has a margin of safety of 25% or more at the neutral DCF assumptions. The shortest list on the site by design: a short list here means the bar is real, not that something is broken. See Passes Everything.
Conviction Pick #
One of a fixed list of durable, well-branded companies this site weights ~30% more heavily in ranking when it clears every filter, on the view that resilient, well-known businesses are more likely to recover after a drawdown. Every stock still has to clear the same 8 filters; this list only affects sort order, not pass/fail.
Today's Shortlist #
The stocks that pass everything, ranked by whichever has the widest margin of safety right now. A sort, not a score: a real, recomputed-every-refresh number. Names that started passing since the last refresh are tagged "Newly qualifying." See Today's Shortlist.
What Changed (Why Now) #
A feed of what is new since the previous data refresh: stocks newly passing all 8 filters, fresh drops to within 10% of the 52-week low, real insider purchases in the last 45 days, and earnings due in the next 7 days. It compares this refresh against the last one, not a calendar week. A stock appearing there is a fact about what changed, not a recommendation. See What Changed.
Screen Builder #
The tool on the screener page that filters every tracked stock on any of 50-plus measures this site computes, sorts by any of them, and lets you save a screen in your browser, send it as a link or download it as a CSV. Each filter shows how many stocks it keeps and how many it would add if removed. A stock with no value for a measure fails a filter on it, and the starting points it offers are only sets of filters, not recommendations. See the Screen Builder.
Buffett Checklist #
This site's 8-point test inspired by Warren Buffett's writing: return on equity (trailing and 5-year), debt/equity, pretax margin, 5-year EPS growth, interest coverage, trading below DCF intrinsic value, and price against owner earnings. Buffett inspired the questions, but the specific cutoffs (11% ROE, 0.5 debt/equity, 15% margin, 7% growth, 5× coverage) are commonly-used, invented thresholds, not numbers he published. To see what Buffett and 24 other investors actually own, open Superinvestors.
Lynch Checklist #
This site's 5-point test inspired by Peter Lynch: PEG, growth rate, debt, valuation and cash flow. Lynch judged different kinds of company by different yardsticks, so the bars depend on the category a stock's growth puts it in: a Fast Grower (20–50% EPS growth), a Stalwart (10–20%) or a Slow Grower (0–10%, owned mainly for its dividend). The exact cutoffs are this site's, not numbers Lynch published.
Compounder at a Fair Price #
A company that grows its profit without swallowing capital, whose profit turns into real cash, that hands cash back to its owners, and whose price hasn't already paid for all of that. The Compounders at a Fair Price page tests four lenses: capital-light growth, profit is real (no earnings-quality red flag), cash to owners (shareholder yield of at least 1%) and a fair price (PEG at or under the bar you pick: 1, 1.5 or 2). There is no score; each lens is cleared or it is not.
Stock Card #
The single detail view that opens when you click any ticker on this site. Every per-stock check lives in it (price against DCF value, the 8 filters, the Buffett and Lynch checklists, Munger flags, earnings quality, shareholder yield, capital needed to grow, PEG and the rest) so one number can't disagree with itself between pages. Every tracked stock also has its own page; browse them in the A to Z directory.
Sector Median #
On the Sector Valuation Map, each sector's reading is the median stock rather than the average, so one outlier can't move it, and a sector needs at least four stocks with a value before a median is shown. Warm (pricier or weaker) and cool (cheaper or calmer) compare a sector with the median of all tracked stocks. A warm tile is a question, not a verdict.
Watchlist #
Your own starred tickers, saved to your browser's local storage. Nothing is sent to a server; it's private to your device and browser, and clearing your browser data clears it too. See your Watchlist.
The Tracked Universe (about 500 stocks) #
The set of about 500 large and mega-cap US-listed companies (the S&P 500, plus a few large caps kept on purpose) this site's screener mechanically re-checks every week (the exact count is on the screener), distinct from the computed portfolio reviewed against the Buffett and Lynch checklists on the homepage. Browse every tracked stock in the A to Z directory.
Dollar-Cost Averaging (DCA) #
Investing a fixed amount on a schedule, regardless of price. The DCA Backtest replays it with real historical closing prices for any tracked stock, and compares it with putting the same total in as one lump sum and with doing either one in the S&P 500 instead. Real history, not a projection.
Real Return #
A return after inflation. A nominal gain isn't a real gain if prices rose faster than your money did. The Real Return tool adjusts a stock's actual price history with the official US Consumer Price Index (from FRED) to show what you actually kept in purchasing power.
Average Buy-In Price (Cost Basis) #
Your own average cost per share: total money in ÷ total shares, across every purchase. Every share counts equally, with no time-weighting and no FIFO/LIFO lot accounting, so it is not tax-lot reporting. The Average Buy-In Price Calculator keeps your purchases only in this browser.
An investing glossary in plain English
This stock market glossary explains the terms used across the site in plain English: P/E ratio, PEG ratio, free cash flow yield, margin of safety, intrinsic value, discount rate, CAPM, RSI, the Altman Z-score, shareholder yield, Form 13F and more. Use it alongside the stock screener and the intrinsic value calculator when a metric is unfamiliar.
