SpaceX enters the indices with 16% gains since the IPO. Yesterday, it entered the Russell 1000 index, with major moves among asset managers.

Twelve trading sessions after its debut on the stock exchange, SpaceX is landing in Wall Street’s major indices. It debuted in the Russell 1000 yesterday, but the main event will come next July 7, when the company will be added to the Nasdaq 100 index of technology stocks.

Inclusion in the major indices is swift, and it comes after SpaceX has built up a 21.5% rise since it jumped onto the American stock exchange, reaching $164.

On June 11, the company raised $7.5 billion by placing 555.6 million shares at a price of $135 per share—an operation that valued the group at $1.77 trillion, with a tranche reserved for retail investors of 20%. It was the largest IPO in history, smashing the global record then held by oil company Saudi Aramco, which raised $26 billion in 2019.

The addition of the group led by Elon Musk to the Russell 1000 index has an immediate first impact: all ETFs and funds that track indices must buy shares of SpaceX in proportion to their weighting.

Although the effective inclusion in the Russell 1000 took place yesterday, the adjustments to the ETFs and index funds that follow the Russell index were carried out on June 26 in the afternoon. In other words, they rebalanced their portfolios to align with the new list of components. This means selling every stock that is removed and buying every stock that is added, simultaneously, in proportion to its weight in the index.

A process that, together with the imminent move to the Nasdaq 100, will—according to Bankinter analysts—cause an “increase in trading volatility.” The firm also notes that position rebalancings are executed quarterly.
