SpaceX’s imminent entry into the Nasdaq-100 is set to widen the index’s volatility advantage over the S&P 500
Executive summary: The Nasdaq-100 has shown markedly higher volatility than the S&P 500, and SpaceX is set to be added to the Nasdaq-100 on Tuesday, with no S&P 500 inclusion expected for at least another year. Adding SpaceX to the Nasdaq-100 could amplify the index’s volatility, widening the performance gap with the S&P 500 and affecting index‑linked funds and investor allocations.
Who is involved: Nasdaq, S&P 500 index providers, SpaceX, investors in Nasdaq‑100 ETFs such as QQQ and QQQM, and broader market participants.
Likely next: After SpaceX’s debut, market watchers will track volatility metrics; a potential S&P 500 inclusion may be considered later, prompting further index rebalancing.
The Nasdaq-100 has exhibited substantially higher volatility than the S&P 500 in recent periods. MarketWatch reports that SpaceX is scheduled to join the Nasdaq-100 on Tuesday, while it will not be eligible for the S&P 500 for at least another year. This timing suggests that the addition of SpaceX could further increase the Nasdaq-100’s volatility relative to the S&P 500. The development highlights differing compositional dynamics between the two major equity benchmarks.
