SpaceX to Join Nasdaq-100 Index Tuesday, Potentially Impacting Index Funds

SpaceX is set to join the Nasdaq-100 index this Tuesday, a significant event that could lead to automatic buying by index funds. These funds collectively manage approximately $800 billion in assets, meaning SpaceX's inclusion will create "automatic demand for shares" as the index adjusts.

Despite SpaceX's market capitalization nearing $2.1 trillion, its initial weighting in the Nasdaq-100 will be less than 1%. This is because Nasdaq calculates company weightings based on the number of shares available for trading. Following its IPO on June 12, less than 5% of the company's capital is in circulation, and a substantial portion of shares are subject to lock-up periods for employees and pre-debut investors.

Analysts believe that SpaceX's inclusion in a major index like the Nasdaq-100 could boost its stock price in the short term due to passive fund purchases. However, they caution that such effects rarely sustain long-term gains. Past examples like Okta saw peaks shortly after joining the index before losing momentum, while others like Palantir maintained upward trends, partly due to their AI business.

Investors will closely watch the expiration of share lock-up periods in the coming months, which will increase the number of SpaceX shares available on the market. According to experts, the company's stock performance will ultimately depend on its financial results and its capacity to justify its high valuation post-IPO.
