2 Space Stocks Down More Than 50% That Could Be the Best Buys of Q4

AST SpaceMobile and Rocket Lab, both down over 60% from their peaks, are presented as potential Q4 buying opportunities in the space sector. AST SpaceMobile plans to launch initial satellite coverage in five countries by year-end with partnerships across 60+ mobile operators, while Rocket Lab has demonstrated strong revenue growth ($234M in Q2, up 62% YoY) and a record $2.4B backlog. Both face execution risks, though Rocket Lab offers a more established business model compared to AST's pre-commercial stage.
