SpaceX just had the largest IPO in history, and its stock is soaring. But shares of other space companies like Rocket Lab actually dropped today, likely because investors are selling their old space stocks to free up cash to buy the new SpaceX shares.

## Idea

Historically, when a massive new company goes public, it temporarily drains money from similar, smaller companies in the same industry as investors rush to buy the new shiny object. SpaceX is having a historic debut, pushing smaller space stocks like Rocket Lab down today. However, Rocket Lab's actual business hasn't changed overnight. Once the initial SpaceX hype settles, these beaten-down space stocks are likely to bounce back as investors return to them.
