L ockheed Martin stock bounced Wednesday after a dreadful Tuesday. Despite the higher stock price, Wall Street has some concerns about the defense contractor, and one analyst even downgraded the shares. Shares gained 2.1% to $419.39 on Wednesday, while the S&P 500 and Dow Jones Industrial Average added 0.8% and 1.1%, respectively.

Facing defense cuts and NGAD setbacks, Lockheed Martin is pitching an enhanced F-35 as a cost-effective “bridge” to sixth-gen fighters, reusing advanced tech while managing significant financial losses.
