Index membership is a market-cap ranking dressed as a verdict, so the notice S&P Dow Jones Indices issued on the 7th [1] tells you only where Nike's equity now sits against 99 other American companies, a fact about the stock, not about shoes. The shoe numbers were already public: 22.9% of the global footwear market last year against 25.9% in 2022 [5], which is three points, or 11.6% of the share Nike had to begin with [1], plus a China business that went from nearly a fifth of annual revenue to about 13% [4], a 35% cut in the mix [8].
Set the two series next to each other and the arithmetic stops being about running. A price 78.4% below its November 2021 high [3] against a share position down 11.6% of itself is a ratio close to seven to one [2], and no plausible forecast of pairs sold closes that gap; what got repriced is margin and the durability of shelf position. The channel is where that lives. The direct-to-consumer push under John Donahoe left sporting goods retailers annoyed enough to fill the space with On and Hoka [8], and taking it back means displacing brands the retailer is currently selling at a rate it likes, which is why Brian Mulberry of Zacks Investment Management allows three to four quarters before a meaningful rebound under Elliott Hill, who has had the job since October 2024 [10][9]. Getting back to $177.51 from $38.40, incidentally, is a 362% move [3].
The challenger's numbers deserve the same division. Asics guides 2026 revenue to 1.05 trillion yen, up 29% and its first year above a trillion [11], with net profit of 120 billion, up 22% and revised up from 110 billion [12]. Back out the growth rates and the prior year was roughly 814 billion yen of revenue [4] on about 98 billion of profit, so the net margin goes from about 12.1% to about 11.4% [5][6] even as chairman and chief executive Yasuhito Hirota credits withdrawing from low-margin businesses [15]. The premium running win is real (Circana put Asics first at 17.4% of the combined US, five-European-country and Japanese premium market for January to September last year [13], and Strava's ranking had the Novablast ahead of the Pegasus [14]), but it is arriving as volume ahead of price.
The bull version of Nike is not silly: wholesale gets repaired inside Mulberry's window, 22.9% steadies, and $38.40 turns out to have been a price rather than an estimate of the business. The bear version is that 13% of revenue from China keeps sliding while Anta and Li-Ning hold the guochao trade [6], in which case 78.4% was generous. The weakest of the three is the middle claim, that Asics now owns premium running, because in 2021 not one runner at the Hakone Ekiden wore Asics [17], and a position that moved that far in five years is borrowed. Seoul Economic Daily also attributes part of Nike's slump to marketing that recycled Air Jordan and Air Max as limited-edition colorways instead of function [16]; the index removal is being read to confirm that story, but it confirms a share price.
On the mechanics of the 21st, the notice as reported carries no flow figure and no change to any other Nike index membership [18], so the size of the forced selling is not something this evidence supports a number for. What would break the read above is next year's share print holding at or above 22.9% while Asics' margin keeps compressing, which would say premium running is a volume business a 22.9% incumbent can walk back into.
