Summary
Walleye Capital, a multi-strategy hedge fund managing about $17 billion, told investors in a letter dated November 5, 2026 that it will simplify its internal equity long-short business and return some capital. According to the letter, chief executive and chief investment officer Will England said the firm will part ways with that unit's leadership and a substantial portion of its investment teams. He described the unit as the firm's weakest strategy since 2023 and said earlier fixes, including new leadership, had not delivered results. The flagship Walleye Opportunities Fund was down in nine of the first 10 months of 2026, and the fund lost 5.9% in October, its worst month since March 2020.
The announcement coincided with a sharp selloff in AI chip stocks. Micron Technology fell 17.46% to close at $656.39, AMD dropped 17.26% to $404.40, and KLA lost 13.35%. The Nasdaq 100 sank 6.4%, its worst session since March 2020. Coverage set Walleye's losses against that decline, although the letter itself does not say the selloff caused them. Walleye will continue to pick stocks through outside managers and its highest-conviction portfolio managers while shifting resources toward volatility and quantitative strategies. Its volatility business posted its best month on record in October.
Walleye's 13F filing for the quarter ended June 30, 2026 listed KLA as its ninth-largest long equity position at $141.4 million, alongside Micron and AMD; those holdings may have changed since. Walleye was one of several multi-strategy and equity funds with a weak October. Millennium's flagship fund lost 2.3%, Marshall Wace's Eureka strategy lost 5.4%, ExodusPoint lost 2.4%, and North Rock Capital lost 2.3%. Engineers Gate is reportedly parting ways with most of its stock team. The source notes that forced selling by funds reducing crowded positions can move stocks regardless of business results, and the letter gives no sizing for further selling.
Fundamentals cited in the source remain strong. KLA reported September-quarter revenue of $4.136 billion, up 28.86%, and guided to $4.7 billion for the December quarter. Micron guided to $61.5 billion of fiscal first-quarter revenue and paused work on a Taiwan plant following a labor dispute. AMD's Data Center revenue rose 97% to $8.546 billion, and the company guided to about $17 billion for the fourth quarter; CEO Lisa Su said PC sell-through slowed late in the quarter as higher memory and component costs weighed on demand. The bear case cited is crowding, with higher memory costs already weighing on PC demand.
