Why these two companies

General Dynamics beat Wall Street's profit estimates in its second-quarter report released Wednesday, July 29, 2026, sending shares to a fresh 52-week high just a day after the U.S. said it intercepted an Iranian missile attack on its forces in the Middle East on July 28, 2026, reigniting demand for U.S. weapons makers. Lockheed Martin, General Dynamics' longtime rival for Pentagon contracts, had already raised its own full-year sales guidance on July 23, 2026 after posting a record order backlog, setting up a head-to-head test of which defense giant's momentum has more room to run into the next trading session.

The research

General Dynamics builds tanks, submarines, and combat vehicles for the U.S. military, plus Gulfstream private jets for wealthy travelers and companies. Lockheed Martin is best known for building the F-35 fighter jet and missile-defense systems used by the U.S. and allied militaries around the world.

One reason to like General Dynamics: it just reported stronger profits than expected and touched a new one-year high stock price the day before its earnings came out, showing steady, broad-based growth across its businesses. One reason to like Lockheed Martin: it just raised its full-year sales forecast and reported its largest-ever pile of unfilled orders, meaning years of future work are already lined up.

One thing to keep in mind about General Dynamics: some of the recent excitement is tied to world events, like rising tension between the U.S. and Iran, and those situations can cool down just as fast as they heat up. One thing to keep in mind about Lockheed Martin: its stock has already climbed a lot in a short period, so some investors worry the good news is already baked into the price and future gains may be harder to come by.

Both companies make their money largely from government contracts rather than everyday consumers, so their stock moves often depend more on defense budgets, contract awards, and world events than on typical retail sales or advertising trends.
