Key Takeaways

- • Alphabet's long-to-short fund count ratio returned above 1.0x after falling below that level in August, while Tesla's ratio fell to 0.54x, its lowest level of the year.
- • Broadcom (AVGO) flipped from short-biased to long-biased as net long exposure rose from 34.1% to 54.1% and its long-to-short fund count ratio increased from 1.79x to 2.53x.
- • The PHLX Semiconductor Sector Index share of constituents with net long positioning rose to 76.7% from 73.3%, indicating modestly more bullish sentiment in semiconductors.
- • Rising interest rates and energy-driven inflation were cited as key macro themes, following a 25-basis-point Federal Reserve rate hike that triggered a global bond selloff.
Summary
Rising interest rates and inflation were key themes shaping global hedge fund positioning in September 2026, according to Data Insights, the institutional hedge fund market intelligence division of Hazeltree. Following a 25-basis-point Federal Reserve rate hike, global bond markets sold off and long-term Treasury yields climbed, while equity market gains were concentrated in a narrow group of AI-linked mega-cap technology stocks. Higher energy prices were cited as a partial driver of the inflation backdrop.
The Data Insights Crowding Report September 2026, formerly the Hazeltree Crowding Report, showed a rebound in the number of funds holding long positions across several Magnificent Seven stocks. Alphabet saw a moderate month-over-month increase in long fund counts, while Meta, Microsoft, Nvidia and Amazon posted modest gains. Apple and Tesla recorded modest declines. On the short side, Meta and Tesla saw notable increases in fund participation and Microsoft a moderate increase, while Nvidia, Amazon, Alphabet and Apple experienced reductions. Tesla's long-to-short ratio fell to 0.54x, its lowest level of the year, leaving Apple and Tesla as the only Magnificent Seven names with more short than long holders by count.
In semiconductors, the report tracked the 30 constituents of the PHLX Semiconductor Sector Index, of which 76.7% showed net long positioning, up from 73.3% the prior month. Broadcom was the monthly Spotlight name. Per Data Insights managing director Tim Smith, its positioning shifted from short-biased to long-biased even as the stock spent most of the month under pressure, with funds using the pullback to rebuild long exposure. Crowding on the long side was most pronounced in Applied Materials, followed by Nvidia and Broadcom. On the short side, Teradyne was the most crowded name, followed by ON Semiconductor and Advanced Micro Devices. The index added Lattice Semiconductor, Qnity Electronics, SiTime and Tower Semiconductor in its annual reconstitution.
Regional single-name data showed notable movers in each region, with more than 10% month-over-month changes in fund counts. In North America, long crowding increased in Booking Holdings and Broadcom among large caps, and in Insulet, WillScot, Pinterest and others among mid caps. In EMEA, Lloyds Banking Group and Glencore led large-cap long increases, while Kering led large-cap short increases. In APAC, mid- and small-cap long increases were concentrated in resource and mining names, including Westgold Resources, Stanmore Resources and Firefly Metals.
Smith said that while market gains were concentrated in AI-linked mega-caps, rising rates and inflation concerns both contributed to volatility, and that the Fed's hike and subsequent market reaction reinforced the prospect that monetary policy could remain restrictive for longer than investors had anticipated. The report draws on anonymized positioning data covering about 16,000 securities across the Americas, EMEA and APAC. Crowding scores are relative metrics that normalize fund counts within region and market-cap groups, and a long position generally signals an expectation of price gains or a hedge, while a short position generally signals an expectation of decline or a hedge against longs.
