What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and IBKR doesn't clear enough of it yet. In its favor: IBKR is currently earning a strong return on shareholders' equity, and has kept that profitability up over five years, not just this year, converts sales into profit at healthy margins, has grown earnings per share at a solid clip over five years, is trading below what a conservative discounted-cash-flow estimate says it's worth - his own "price is what you pay, value is what you get" test, not a fixed multiple ceiling, and trades at a reasonable multiple of owner earnings, his own term for the real cash a business could pay out. Where it comes up short: IBKR carries more debt relative to equity than he typically tolerates, and doesn't cover its interest expense as comfortably as he'd want.

- ROE (5yr avg) > 11% ✓
- Debt/Equity < 0.5 ✕
- Pretax margin > 15% ✓
- EPS growth (5yr) > 7% ✓
- Interest coverage > 5x ✕
- Trading below intrinsic value (DCF) ✓
- Price vs. owner earnings < 25x ✓
Lynch looked for growth stories that weren't overpriced for that growth, and IBKR falls short of his bar. In its favor: IBKR is growing earnings 20-50% a year, his classic fast-grower zone, and is generating real cash to back up a fast grower's higher price tag. Where it comes up short: IBKR doesn't clear the tighter PEG bar a fast grower needs to justify its pace, is leaning on more debt than he liked a growth story to carry, and is priced above what he'd pay even for a company growing this quickly.
- PEG < 1 (stricter for fast growers) ✕
- EPS growth 20%-50% ✓
- Debt/Equity < 0.5 ✕
- P/E < 40 ✕
- Price/FCF < 40 ✓
- Bonus: insiders buying (90d) 3 buys, ~$0.7M
Quantitative approximations of each investor's documented approach, not endorsed by either investor or their estates - commentary, not this site's actual ranking criteria. Buffett never published a numeric checklist: only 2 of his 8 checks here trace to his own documented concepts ("owner earnings," from his 1986 shareholder letter, and "price is what you pay, value is what you get," his case against fixed P/E/P/B ceilings) - the other 6 (ROE, debt, margins, growth, interest coverage) use commonly-cited thresholds that are not numbers he himself published. The 8 hard filters below (plus the Munger check and Graham margin of safety) are this site's real, mechanical screen and are computed completely independently of the checklists above.

Frequently asked questions about Interactive Brokers Group
What kind of company is Interactive Brokers Group?
Interactive Brokers runs an electronic brokerage that lets clients trade stocks, options, futures and currencies across many markets. Brands and businesses it owns include IBKR, Trader Workstation and IBKR Lite. This site groups it with Financial Services stocks.
Why does Interactive Brokers Group have no margin of safety on this site?
This site's DCF values a company from its free cash flow, and that does not fit financial companies, whose operating cash flow swings with client money, loans and trading rather than with what is left over for owners. So IBKR gets no margin of safety; judge it on the other checks on this page, such as its filters, shareholder yield and ranking against its peers. The method is in the Intrinsic Value Calculator.
How many of this site's 8 value filters does Interactive Brokers Group pass?
IBKR passes 2 of 8. It passes Market Cap > $25B ($140.2B) and EPS Growth YoY > -5% (+17.4%). It misses Trailing P/E < 25 (119.14), PEG Ratio < 1.5 (1.81), Price/Book < 8 (22.56) and Price/Sales < 7 (11.96). vs 50-day MA (±12%) and vs 200-day MA (±12%) were not evaluated, because the moving-average checks only run on stocks that clear the fundamentals first. The 8-filter list shows every stock that passes all of them.
