HEDGE FUNDS SHIFT POSITIONING IN OCTOBER AMID SHARP ROTATION OUT OF LARGE TECHNOLOGY STOCKS, DATA INSIGHTS REPORTS
Short fund participation rises across Amazon, Apple, Nvidia and Meta, while Tesla attracts more long holders and fewer short holders
Markets saw a sharp rotation, particularly in the largest technology stocks, with the Nasdaq Composite down about 5% and the S&P 500 down about 1%. Yet the broader market outside of tech performed well, with the S&P 500 Equal Weight Index gaining about 5%. Meanwhile, AI-related securities struggled with credit levels and private credit exposure to AI data center lending. Semiconductor names were significantly impacted, with the SOX index falling roughly 16%, according to Data Insights, the institutional hedge fund market intelligence platform and a division of Hazeltree.
The Data Insights Crowding Report October 2026 (formerly the Hazeltree Crowding Report) showed that within the Magnificent Seven, Tesla posted a moderate month-over-month increase in the number of funds holding long positions, while Nvidia and Alphabet posted modest gains. Apple declined moderately, while Amazon, Microsoft, and Meta were modestly lower or flat. Notable short-holder increases appeared in Amazon, Apple, Nvidia, and Meta, while Microsoft saw a moderate increase and Alphabet a modest one. Tesla stood out for being the only name where short holders declined.
The long-to-short fund count ratio for Apple fell to 0.65x, its low for the year and a third consecutive month below 1.0x, while Meta, Amazon, and Microsoft each hit their own 2026 lows on the same measure; Alphabet held just above parity at 1.02x.
Overall semiconductor sentiment turned less bullish in October, with the share of constituents exhibiting net long positioning slipping to 70.0%. Data Insights tracks activity through the PHLX Semiconductor Sector Index™, which includes 30 of the largest U.S.-traded semiconductor companies.
Advanced Micro Devices (AMD) stood out as it flipped from long-biased to short-biased in October as measured by both the long-to-short fund count ratio (falling below parity, from 1.18x to 0.94x) and net long exposure (falling below 50%, from 77.9% to 44.4%).
On the long side, crowding is now most pronounced in Nvidia, followed by Broadcom and Applied Materials.
On the short side, Entegris is now the most crowded name, followed by ON Semiconductor and Advanced Micro Devices.
The Data Insights Crowding Report examines hedge fund long and short crowding across the Americas, EMEA and APAC during October 2026, based on Data Insights' analysis of anonymized data covering approximately 16,000 securities on its proprietary securities-finance platform, representing more than 700 global funds. It includes the ten most crowded regional long and short positions, broken out by large-, mid-, and small-cap categories.
Data Insights defines the crowding score as a relative metric that normalizes the number of funds in Hazeltree's community that are long or short a given security within a predefined group (by region and market cap) relative to its peers. When a fund goes long a stock, it generally means it either expects the stock's price to rise or is using the position to hedge its exposure to shorts. Conversely, when a fund shorts a stock, it generally means it either expects the stock's price to decline or is hedging its long exposure.
"The month of October ushered in a sharp rotation out of some of the largest technology stocks as some of the major indices fell, but in an interesting contrast non-technology sectors performed well," commented Tim Smith, managing director, Data Insights, Hazeltree. "AI infrastructure builders experienced some struggles with credit levels, most notably CoreWeave, which saw its default insurance costs widen and its 2032 bonds yield close to 15%, approaching levels typically associated with distressed debt."
Smith added, "CoreWeave also captured our attention with a drop in its long-to-short fund count ratio (from 0.60:1 in September to 0.53:1 in October) and a decline of about 37% in its stock price during October, including a 15% drop on October 14. Net long exposure, measured in quantity, also weakened from about 80% in the first four months of the year to 55.9% as of October."
