Nike’s removal from the S&P 100 is a rules-based index event, but it reflects a reality already visible in the share price: the company has lost substantial market value since 2021 and has yet to convince investors its turnaround can restore its former growth profile.

Nike will leave the S&P 100 on Sept. 21 as part of the index’s quarterly rebalance, ending a run of nearly 18 years among the benchmark’s largest constituents. Dell Technologies, Palo Alto Networks, Arista Networks and SanDisk will take the vacated seats, all promoted from the S&P 500. Nike remains in the broader index.

Shares closed Friday at $38.40, a 12-year low, down more than 76 percent from their November 2021 peak. Market capitalization has fallen to roughly $57 billion from about $264 billion over the same period. Index-tracking funds are expected to adjust holdings accordingly.

After several years emphasizing direct-to-consumer sales, Nike has increasingly focused on rebuilding wholesale relationships. The latest results show wholesale has returned to modest growth while direct sales remain under pressure, helping stabilize revenue even as investors await clearer evidence of sustainable growth. Greater China remains a key challenge, with the market continuing to trail Nike’s recovery in North America.

For the sporting goods industry, Nike’s departure from the S&P 100 carries little operational significance. The company remains by far the sector’s largest revenue generator and stays in the S&P 500. As a market signal, though, it is significant: the index’s rules-based methodology confirms what the share price has already shown, that Nike has yet to convince investors its turnaround can restore its former growth profile.
