The Procure Space ETF (UFO) and Tema Space Innovators ETF (NASA) are witnessing remarkable performance as they reach record prices of $68 and $43, respectively, fueled by the excitement surrounding the upcoming SpaceX IPO. This IPO is anticipated to be the largest in history, with an initial valuation exceeding $1.7 billion. The growth of these ETFs is also supported by significant stock price increases in leading space companies, with Rocket Lab up 436% and Planet Labs soaring 766% over the past year. However, the surge in valuations raises concerns about potential overvaluation and the risk of profit-taking by investors once the IPO occurs. Notably, while companies like Rocket Lab and Planet Labs are experiencing revenue growth, they have not yet achieved profitability, with Rocket Lab's forward price-to-sales ratio at 91, significantly higher than the sector's median. As the market adjusts, these ETFs may face corrections as they deviate from historical averages.
