SpaceX Joins Nasdaq-100, Widening Its Volatility Gap With S&P 500
SpaceX's addition to the Nasdaq-100 on Tuesday could deepen the volatility divide between that index and the S&P 500, where it won't qualify for at least a year.
SpaceX is set to join the Nasdaq-100 on Tuesday, a move analysts say will likely amplify the already-pronounced volatility gap between that index and the broader S&P 500, where the private aerospace giant remains ineligible for the foreseeable future.
The Nasdaq-100, which skews heavily toward high-growth and technology-oriented companies, has historically swung more dramatically than the S&P 500 during periods of market stress and euphoria alike.
