Why is General Motors hitting the brakes

General Motors ($GM) continues to face headwinds, falling nearly 4% in premarket trading despite second quarter sales and adjusted EBIT of $3.04 billion beating profit expectations. This follows a pattern previously seen in 2025, which saw its 8.9% decline in the afternoon after fourth quarter results on Jan. 28, despite strong earnings of $1.92 per share and revenue of $47.70 billion. Investors may be reacting to a drop in year-over-year profits or cautious guidance. For the latest information on $GM, keep an eye on financial news sites like Bloomberg or trading apps like Robinhood.

Lockheed Martin Earnings Miss: What's Next

Lockheed Martin ($LMT) fell 8% premarket as second quarter revenue of $18.16 billion fell short of analysts' $18.57 billion estimates. This follows a weak fourth quarter and a 9.2% drop in January 2025, although a 3% gain in April showed strength. Some posts confirm the earnings report as a key driver, but the stock's future depends on trends in the defense sector. Want to know $LMT's next move?
