RTX Corporation, formed from the 2020 merger of Raytheon and United Technologies, is a diversified aerospace and defense powerhouse with three strong segments: Collins Aerospace, Pratt & Whitney, and Raytheon. The stock has delivered exceptional performance, surging nearly 58% over the past year and trading near its 52-week high of $206.48. This momentum reflects robust commercial aerospace recovery and elevated global defense spending amid geopolitical tensions.

The bull case centers on a massive defense backlog exceeding $200 billion, strong aftermarket revenue from installed engine and avionics bases, and secular tailwinds from rising NATO defense budgets. The commercial aerospace cycle remains favorable with airlines expanding fleets.

Bear case considerations include a P/E of 30.13, which is elevated for a defense contractor, suggesting much of the growth story is priced in. Pratt & Whitney's GTF engine quality issues created significant warranty costs, and margin pressure could persist. The stock's rapid appreciation leaves limited near-term upside potential.

As a Dividend Aristocrat, RTX offers reliable income growth, though the current yield has compressed with price appreciation. Overall, RTX remains a high-quality core holding for aerospace and defense exposure, though new investors should consider the stretched valuation.

RTX Corporation stands as a formidable aerospace and defense juggernaut, offering investors a balanced exposure to commercial aviation recovery and heightened global defense spending. The stock has shown remarkable resilience, rallying from a 52-week low of $112.27 to trade near record highs, largely putting the Pratt & Whitney GTF engine concerns in the rearview mirror. With a P/E ratio of 29.40, the valuation is currently rich compared to historical norms, suggesting that the market has already priced in an optimistic growth trajectory. While the company boasts a record backlog and strong aftermarket revenue from Collins Aerospace, the premium price point and lingering supply chain constraints warrant a cautious approach for new capital. Nevertheless, RTX remains a high-quality core holding for long-term industrial portfolios.
