Historical Performance of Largest IPOs Offers Caution for SpaceX Debut

As SpaceX targets a historic $2 trillion valuation for its upcoming initial public offering, an analysis of the five largest IPOs in stock market history suggests caution for early investors. The study examines the post-IPO performance of Saudi Aramco, NTT DoCoMo, Alibaba, Enel, and Visa, adjusted for inflation. While Visa significantly outperformed the market with a 1,912% return since its debut, the other four companies largely underperformed or declined in value over time. Saudi Aramco, for instance, remains down 9% since its 2019 listing. The data indicates that massive hype often coincides with peak valuations, leaving little room for error and resulting in subsequent drawdowns. With SpaceX potentially launching at a valuation comparable to Aramco’s current level but with significantly lower revenue, the article argues that much future growth is already priced in. Consequently, historical patterns suggest that waiting for post-IPO price corrections may be a more prudent strategy for investors than buying on day one, although outliers like Visa remain possible.
