How a stock ends up on this site.

No company can pay to appear here

There is no sponsored placement, no "featured stock" upsell, and no affiliate link tied to any stock, broker or trading platform. A stock appears on the Passes Everything list because it cleared every filter this week, not because anyone bought a slot.

The site does sell clearly labeled display ad space (see Advertise for exactly what is and isn't for sale), and that is all an advertiser buys: an ad never changes which stocks pass, how they rank or what a page says. If any of this ever changes, this page will say so, clearly and in advance.

The homepage portfolio: a rule, not a list

This portfolio is not hand-picked and then left alone; it's recomputed from a disclosed rule every time the site's data refreshes. A stock qualifies only if it clears at least 6 of this site's 8 mechanical filters, clears at least one of the Buffett or Lynch checklists (the Buffett/Lynch checklists themselves are our interpretations of publicly known frameworks, not endorsed by either investor or their estates; see the methodology section), and, unless you turn that requirement off with the toggle above the portfolio, shows a positive margin of safety under this site's neutral DCF baseline. One pick per sector, the strongest qualifier by margin of safety; however many sectors actually have a qualifier is how many stocks are shown, never padded to a fixed count.

Because the rule runs live, a stock's presence in the portfolio can change the moment it stops clearing the bar; there's no separate "under review" grace period the way an earlier version of this page described. The rule itself, and its exact thresholds, are stated in full above; nothing about which stocks qualify is a discretionary call once the rule is applied.

The screener, and every tool built on it

The screener mechanically applies the same 8 hard filters to every stock on a fixed list of about 500 large and mega-cap US-listed companies (the S&P 500, plus a few large caps kept on purpose) (the exact count is on the screener), every week, with no manual override. The site does not scan the whole market (no free data source allows that) so a stock outside that list never appears. Inside it, a stock either clears a threshold or it doesn't; there's no discretionary "but we like it anyway" exception built into the pass/fail logic.

The same standard holds across the rest of the toolkit: the Crash Indicator, the Mean Reversion and Sustainable Dividend screeners, the screens built from each company's SEC filings (Earnings Quality, Shareholder Yield, Capital-Light Compounders and Compounders at a Fair Price), and Superinvestors. Every number shown is real and independently checkable. Where a tool does roll its checks up (Earnings Quality's Strong / Mixed / Weak rating, Mean Reversion's optional Rebound Rank) the page states the rule or lets you set the weights yourself, and the Crash Indicator deliberately has no single composite score at all.

Where the numbers come from

Every figure traces back to one of these public or free-tier sources and is refreshed on a regular schedule, most of it weekly. Each page shows its own "as of" date, and where a number isn't available for a stock the page shows "n/a", not a guess. On any stock page, click a number to see the 10-K filing and fiscal year, or the provider and fetch date, behind it.Disclosures covers each source's known limits.

How we check our own numbers

• Every weekly refresh is validated. Each data file is checked against a written contract before it replaces the old one: the fields it must have, how many stocks it must cover, plausible ranges, and that it was actually rewritten. A file that fails is rejected and last week's copy stays up.
• The math is tested a second way. Automated tests recompute each tool's results independently and fail if they drift: for example, the price-chart data is compared bar by bar with the full price history, and the shareholder-yield figures are cross-checked against the earnings-quality filings data.
• The thresholds are on the page. The filter cut-offs, the DCF baseline and the checklists are written out where they're used, and the glossary defines every term; a number the glossary quotes is tested against the code that uses it.

Educational, not advice

Nothing here is personal investment advice. Backtests, crash replays and the sample portfolio are hypothetical and shown with hindsight. Disclosures has the details.

Corrections

Free data providers occasionally mis-tag a filing or lag a price update. If you spot a number that looks wrong, tell us via Contact. We'll check it against the source and fix it if it's actually wrong, not just because someone disagrees with the conclusion.
