RTX vs RYCEY: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: RTX is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. RTX and RYCEY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined RTX and RYCEY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

RTX Corporation (RTX), formerly Raytheon Technologies, is one of the world's largest aerospace and defense companies. It operates three businesses. Collins Aerospace supplies avionics, interiors, actuation, and other systems for commercial and military aircraft. Pratt & Whitney designs and manufactures jet engines for airliners (including the geared turbofan) and military aircraft, and earns substantial recurring revenue from servicing its large installed engine base. Raytheon, the defense segment, builds missiles, missile defense systems (including Patriot), radars, and other advanced defense electronics for the US military and allied governments.

Rolls-Royce Holdings plc is a British industrial company that designs and services large engines and power systems across three businesses. Civil Aerospace makes the Trent family of widebody jet engines (Trent XWB, Trent 7000, Trent 1000) and earns most of its money not from selling engines but from long-term service agreements tied to how many hours those engines fly, so revenue compounds with global air travel. Defence supplies engines and systems for military aircraft, naval vessels and submarines, including the propulsion for nuclear submarine programs, and carries a long order backlog. Power Systems (the MTU brand) builds large diesel and gas engines and generator sets for data centres, marine, defence and industrial use. The company also has a separately run Rolls-Royce SMR unit pursuing small modular nuclear reactors, an emerging long-duration opportunity rather than a current earnings driver.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• RTX drivers: Commercial aftermarket; Defense backlog and missiles.
• RYCEY drivers: Aftermarket tied to flying hours; Margin transformation.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: RTX faces program-execution risks, most visibly the Pratt & Whitney geared-turbofan powder-metal inspection issue that forced costly engine removals and weighed on cash. For RYCEY, rolls-Royce is a cyclical industrial whose aftermarket profits depend on widebody air travel, so a downturn in long-haul demand, a fuel or travel shock, or a fleet grounding would hit the flying-hours revenue that drives the thesis.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick RTX if you believe its drivers more; RYCEY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the RTX and RYCEY guides.

RTX. RTX trades as a large, dividend-paying aerospace and defense blue chip valued on its huge backlog, recurring aftermarket revenue, and dual commercial-defense exposure rather than rapid growth. Its multiple reflects steady, cash-generative franchises balanced against program-execution risk like the geared-turbofan issue, with the dividend and backlog supporting the shares.

RYCEY. Rolls-Royce reports in pounds sterling and its primary listing is in London (RR.). US investors usually buy it as the over-the-counter RYCEY ADR, so the dollar price reflects both the underlying share and the pound-to-dollar exchange rate, and quoted figures convert from GBP. The 2025 results capped a multi-year turnaround that restored margins, free cash flow and net cash, and management raised its 2028 targets alongside a large buyback program. All figures are approximate as of the FY2025 report and refresh with each result; verify against Rolls-Royce's investor relations page or your broker.

Headline figures (approximate, early 2026): RTX shows revenue (ttm) ~$80 billion, operating margin ~10-12%, backlog Very large (over $200 billion, commercial plus defense), net income (ttm) Several billion dollars; RYCEY shows underlying revenue (fy2025) ~£20.1 billion, up ~14% year on year, underlying operating profit ~£3.5 billion, a ~17.3% operating margin (up from ~13.8%), free cash flow ~£3.3 billion, with a net cash balance of ~£1.9 billion, civil aerospace segment revenue ~£10.4 billion (up ~15%), operating profit ~£2.1 billion.

RTX and RYCEY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
