SpaceX IPO slump underscores risk for small investors

Elon Musk’s SpaceX saw its market capitalisation tumble by roughly $1 trillion after its recent stock offering, leaving investors who bought at the IPO price with steep losses. A similar pattern unfolded for Czech‑based CSG, whose shares fell by dozens of percent from the first trading day. Historical analysis shows that IPOs, on average, underperform the broader market; a study of the fifty largest IPOs in the past five years found only about a quarter beat the S&P 500.

At the same time, Wall Street funds are turning attention to a handful of smaller companies in the space and defense sector that are benefitting from rapid growth in satellite communications, laser systems and military drones. Firms such as AST SpaceMobile, Rocket Lab, Planet Labs, Kratos Defense, nLight and AeroVironment have reported strong revenue gains and are becoming focal points for investors seeking exposure to next‑generation aerospace technologies.
