Nike (NYSE: NKE) is being removed from the S&P 100 index before US markets open on Monday, September 21, ending a run in the mega-cap gauge that stretched back roughly 18 years. The stock closed around $38 on Friday, down about 40% this year and roughly 78% from its late-2021 peak, a collapse that has erased more than $220 billion in market value and dropped the world’s most recognizable sportswear brand out of the top tier of American companies by size.
S&P Dow Jones Indices confirmed in its quarterly rebalance that Nike leaves alongside Honeywell Aerospace, Simon Property Group and Colgate-Palmolive, and that the four seats go to Dell Technologies, Palo Alto Networks, Arista Networks and SanDisk, every one a technology company. A consumer icon, a mall operator and two mature industrials are out; servers, cybersecurity, cloud networking and AI memory are in.

Nike’s exit caps one of the steepest declines among large US consumer companies this cycle. The stock has fallen about 78% from its late-2021 peak near $180, and its market value has dropped from roughly $280 billion at that high to about $57 billion now, according to TradingView data. That contraction is what pushed Nike below the size threshold the S&P 100 is built to capture, and it is the consequence of years of business decline rather than a fresh cause of anything. The index change formalizes what the share price had already made clear.
The scale of the drawdown is easier to grasp against where Nike sat five years ago. In late 2021 it was a roughly $280 billion company, larger than most of the S&P 500 and a fixture near the top of every consumer-sector ranking. The stock now trades at levels last seen more than a decade ago, and the market value that remains would place it well down the league table of US large caps rather than among the mega-caps the S&P 100 is designed to hold. A fall of this depth in a brand this established is rare, which is part of why the removal drew the attention it did, even though the mechanics of the index change are modest.
Why Nike Fell: Direct-to-Consumer, China, and New Rivals
Nike’s fiscal 2026 results showed revenue of $46.4 billion, essentially flat and down 2% on a currency-neutral basis, per financial disclosures reported by IBTimes. The weakness sat in the parts of the business Nike had bet on: Nike Direct revenue fell 6%, Nike Brand Digital fell 12%, and Converse dropped 31%, while traditional wholesale revenue actually rose 6%. That pattern reflects the unwinding of a direct-to-consumer strategy that pulled Nike away from retail partners to sell more through its own apps and stores, a bet that left it exposed when its own channels slowed and the wholesale shelves it had walked away from were harder to win back.
Greater China, once Nike’s most reliable growth engine, has been a persistent drag amid weaker consumer spending and stronger local competition. At home and across running and training, newer performance brands such as Hoka and On have taken share Nike long treated as unassailable, forcing it to compete on innovation in categories it used to define. Chief executive Elliott Hill’s turnaround, rebuilding wholesale relationships and clearing inventory, is the effort investors are now watching, and the index removal lands in the middle of it.
Investor Takeaway
The fall is a business story, not an index story: revenue is flat, Nike Direct and Digital are shrinking, and Greater China remains weak, so the turnaround under Elliott Hill, not the rebalance, is what decides where the stock goes next.
Why the Removal Matters Less Than It Looks
The S&P 100, or OEX, is tracked by a modest set of funds, a few billion dollars of assets, against the trillions benchmarked to the S&P 500, so the mechanical selling triggered by Nike’s exit is minor, especially given how small its index weight had already become. A stock leaving the S&P 500 would force widespread, automatic selling from the vast pool of funds that replicate it; leaving the much smaller S&P 100 does not carry anything close to that weight.
Forbes framed the exit as one that may mark a capitulation point after years of decline, a view worth attributing rather than asserting, since an index change tells you where a stock has been, not where it is going. For long-term holders, the more useful read is that the removal formalizes what the share price already showed, and the turnaround under Elliott Hill, not the rebalance, will decide what comes next. The date to watch is not September 21 but Nike’s next earnings, where the evidence of whether the wholesale rebuild and inventory cleanup are working will actually show up.
Who’s Moving In: SanDisk and the AI Swap
The clearest way to read the rebalance is through the company taking one of Nike’s seats. SanDisk (NASDAQ: SNDK), the flash-memory maker spun out of Western Digital last year, jumped 11.9% to about $1,740 and is up more than 600% this year, on booming AI data center demand that lifted its NAND flash revenue roughly 70% quarter-on-quarter, with hedge fund holdings in the stock rising 125% in the second quarter.
SanDisk now carries a market value near $255 billion, more than four times Nike’s, so the company joining the index is worth roughly quadruple the icon leaving it. FinanceFeeds’ own SanDisk $2,650 bull versus $780 bear breakdown cautions that a stock trading near 10 times forward earnings after a run that large carries late-cycle memory risk, so the enthusiasm is not without a counterweight.
SanDisk, joining the S&P 100, is worth about four times Nike, which is leaving it, a snapshot of capital rotating from consumer brands to AI infrastructure. Data: TradingView / company filings, as of September 5 · Chart: FinanceFeeds.The swap is the index-level version of a rotation playing out across the market. All four names leaving the S&P 100 are mature businesses in mature industries, and all four arriving sit in chips, cloud, cybersecurity and storage, the infrastructure of the AI build-out. The same shift of capital toward that build-out is visible in the corporate cost cuts documented in the 2026 tech layoffs tally, where companies have trimmed payroll while pouring record sums into data centers and chips, the spending that names like SanDisk, Arista and Dell now supply. Nike’s exit is one data point; the direction of the whole rebalance is the signal.
Investor Takeaway
The rebalance swaps four consumer and industrial names for four AI-infrastructure names, so the signal to watch is not Nike’s exit itself but the rotation it marks, with the incoming SanDisk worth about four times the outgoing Nike.
