AI Sector October Sell-Off Hits Hedge Funds Hard, Marshall Wace Strategy Drops Over 5%
nashnova research
October's tech rout dragged global hedge funds to roughly a 3% loss, with $80 billion Marshall Wace's flagship strategy falling 5.4% in a single month — the market is repricing when AI spending will actually pay off.
How bad was it for Marshall Wace?
The firm's core Eureka strategy fell 5.4% in October. Its year-to-date gain shrank to just 5.3%. This means → nearly half of the year's profits were wiped out in one month.
The data-driven Tops strategy dropped 3.6%, barely clinging to a 1.3% positive return for the year.
In plain terms = when a top-tier fund managing $80 billion sees both main product lines bleed at once, it signals a broad liquidation of AI positions — not a single bad bet.
How far did tech stocks actually fall?
The Nasdaq 100 slid more than 10% from its October 6 all-time high, entering a technical correction — the term for a pullback exceeding 10% from a peak.
Intel crashed 29% in a single session, its worst one-day drop since 1974. This means → even legacy chip giants get no mercy once the market questions the AI narrative.
A string of underwhelming tech earnings deepened the central doubt: when will the massive capital pouring into AI infrastructure turn into profit?
Not just equities — bonds bled too?
Euro-area bond markets were hit simultaneously: rising oil prices combined with a deepening French political crisis drove French and Italian government bonds sharply wider against German Bunds.
This reflects pressure on the relative-value trades — strategies that bet on the spread between two types of bonds narrowing or widening — that hedge funds rely on heavily.
In plain terms = hedge funds expected bond positions to cushion equity losses; instead both sides fell together, and the hedge broke down.
How did other funds fare?
Macro fund Graham Capital's discretionary strategy lost 1.8% in October; its year-to-date gain shrank to just 1.2%.
Its systematic macro strategy, however, was nearly flat for the month and still sits on a 21.6% year-to-date return. This means → within the same firm, model-driven strategies proved far more resilient than human-judgment ones.
According to PivotalPath, equity-focused strategies globally bore the heaviest damage; the industry's year-to-date gain remains in the mid-single digits.
What to watch next?
The core tension behind this sell-off: AI infrastructure spending keeps expanding, but the timeline for profit remains unclear.
How the market reprices that logic will determine whether hedge funds can rebuild positions and recover losses.
Put simply = the money has been spent; the question is when it earns back — until that answer arrives, the volatility won't stop.
