What stands out about RTX?
- The share price implies 21.3% yearly growth. At $194.71, RTX's free cash flow of $6.77 per share would have to grow 21.3% a year, fading to 2.5% by year 10, for this site's DCF (10% discount rate) to match the price. This site's baseline starts at 8%, so the price asks for more growth than the baseline. Change the assumptions.
- Misses 2 of the 8 value filters. It fails Trailing P/E < 25 (31.26) and PEG Ratio < 1.5 (2.97); the other 4 pass and 2 were not evaluated. See every filter.
- The margin of safety is falling. It went from -32% on Oct 7 to -69% on Oct 23 across 5 weekly readings. See the trend.
- Weakest against peers: return on equity. At 13% (peer median 22%) it ranks 9th of 12 among aerospace & defense stocks this site tracks. See the ranking.
- Balance sheet in the grey zone. Its Altman Z″-Score is 2.18; below 1.1 is the distress zone, 1.1 to 2.6 the grey zone. See the Altman Z″-Score list.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and RTX doesn't clear enough of it yet. In its favor: RTX is currently earning a strong return on shareholders' equity, and earns many times its interest expense, so debt service isn't a worry. Where it comes up short: RTX and its five-year average return on equity falls short too, so this isn't just a one-off dip, carries more debt relative to equity than he typically tolerates, runs thinner pretax margins than he'd like to see, hasn't grown earnings per share fast enough over five years to impress him, is trading above what a conservative discounted-cash-flow estimate says it's worth right now, and trades rich relative to owner earnings, the real cash the business could pay out.

Lynch looked for growth stories that weren't overpriced for that growth, and RTX falls short of his bar. In its favor: RTX is growing earnings 20-50% a year, his classic fast-grower zone, isn't asking too much even by a fast grower's usual richer multiple, and is generating real cash to back up a fast grower's higher price tag. Where it comes up short: RTX doesn't clear the tighter PEG bar a fast grower needs to justify its pace, and is leaning on more debt than he liked a growth story to carry.

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.

How much have RTX shareholders gained per year?
Not enough clean earnings history to compute this for RTX yet - a loss year in the window breaks the growth math rather than faking a number through it.
An earnings-based proxy, not a stock-price total return - it doesn't capture multiple expansion/contraction or reinvested dividends. EPS from RTX's own 10-K filings; dividend yield is the current trailing yield on today's price, from the same weekly fetch as the rest of this site.
What do RTX's 10-year financials show?
From RTX's own 10-K filings (SEC EDGAR): up to the last 10 fiscal years. Press any year's bars for the exact figures.
