FTSE Russell Eases Index Entry for Large-Caps

FTSE Russell modified its regulations, streamlining the inclusion process for newly minted mega-cap companies into its US indexes. This adjustment opens the door for passive investors to gain quicker access to shares in high-profile listings such as SpaceX. Previously, large-cap companies could join the Russell series of indexes only after five days of trading if their publicly available float was smaller than the index threshold. Under the revised rules, companies no longer need to wait for the indexes' subsequent annual review to be included; the changes are effective immediately.

This initiative paves the way for SpaceX, co-owned by the London Stock Exchange Group, to join the indexes once it goes public. Elon Musk's satellite communication company is expected to go public within weeks, a move widely anticipated by analysts to be the largest in history.

If included, passive fund managers mandated to acquire shares in index constituents will create substantial demand for SpaceX stock. Index providers are actively preparing for a wave of large IPOs later this year. SpaceX, alongside artificial-intelligence competitors OpenAI and Anthropic, are among those expected to drive blockbuster IPOs.


Impact on Index Effectiveness and Valuation

The revised entry criteria could have significant implications for index composition. S&P Dow Jones Indices suggested during its consultation period that adhering to existing rules could "impact the overall index's effectiveness as a benchmark."

SpaceX is targeting a public valuation of approximately $1.5 trillion. In comparison, ChatGPT owner OpenAI could also achieve a trillion-dollar valuation. News Corp, owner of The Wall Street Journal and Dow Jones Newswires, announced a content-licensing partnership with OpenAI. The Wall Street Journal reported that Nasdaq unveiled its own fast-entry rules for newly listed companies in March. S&P Dow Jones Indices also stated it was conducting a similar rule change consultation in April.

Faster entry for mega-cap companies into indexes is intended to reflect significant market developments more promptly, while upholding governance and investability standards for index users, according to Arne Noack, FTSE Russell's Head of Equity and Multiasset Indexes for the Americas.

However, trading in newly listed stocks often exhibits volatility. The obligation for passive funds to buy shares included in indexes could expose them to the initial price surge typically observed after an IPO. Samuel Kerr, Global Head of ECM at Mergermarket, noted the high risks associated with IPO investing, especially with the substantial premium valuations projected for mega-cap IPOs like SpaceX. He questioned whether passive funds should be compelled to purchase these stocks.

The rule change will accelerate the inclusion of US Russell indexes, aligning with FTSE's existing global and UK-specific equity index fast-entry rules.
