Chip Stocks Surge Yet Face Heavy Shorting: Goldman's Tech Long-Short Ratio Hits Lowest Since 2016
nashnova research
U.S. semiconductor stocks rallied over 8% last week, but hedge funds ramped up single-stock shorts instead of covering. Goldman's tech long/short ratio fell to 1.5 — the lowest since records began in 2016 — as fast money converted index optimism into stock-level bearish bets.
Chip stocks surged — so why were hedge funds selling?
U.S. semiconductor stocks posted their best weekly gain since April, rising over 8%; the S&P 500 gained 2.5% over the same period.
Yet Goldman Sachs' Prime Brokerage weekly report shows hedge funds were net sellers of U.S. equities for the second straight week. Globally, single stocks have been net sold for nine consecutive weeks.
This means → the index rallied, but the institutions managing the largest pools of capital do not buy this rebound — they are using it as cover to add short positions.
"Close the index hedge, short the single stock" — what does that look like?
Short positions in U.S.-listed ETFs dropped 8.6% in a single week — the largest covering in nearly seven months — concentrated in large-cap equity, credit, and tech ETFs.
At the same time, U.S. single-stock net selling hit -1.7 standard deviations (one-year baseline), driven almost entirely by new short additions.
In plain terms = hedge funds had been hedging by selling single stocks and buying index exposure. Now they have flipped the trade entirely — unwinding index protection and shorting individual names directly.
A tech long/short ratio of 1.5 — what does that signal?
Goldman data shows the U.S. information-technology sector long/short ratio fell to 1.5, the lowest since records began in 2016 and down roughly 30% from the June peak of 2.14.
The long/short ratio — total long dollar value divided by total short dollar value — is the core gauge of how bullish or bearish hedge funds are on a sector.
This means → for every $1.50 in long positions, there is $1.00 in shorts. Tech is near parity on hedge-fund books — the most pessimistic positioning in nearly a decade.
Multi-PM funds posted their worst month ever in October — how bad is the backdrop?
Goldman's monthly investor report shows multi-manager funds — so-called "pod shops," where multiple portfolio managers trade under one platform — recorded their worst monthly performance on record in October, surpassing March 2020.
Global equity net selling stood at -0.7 standard deviations; deleveraging accelerated, with long selling outpacing short covering at a ratio of 2.8 to 1.
This reflects an industry-wide deleveraging, not isolated fund decisions — losses are forcing funds into involuntary position cuts.
Which regions and sectors were hit hardest?
Asia ex-Japan long selling reached -2.74 standard deviations — the most extreme outflow on the global book. Asia-focused funds lost roughly 1.5% during the week.
Nine of eleven global sectors saw net selling, led by information technology, healthcare, and financials. Energy and real estate were the only net-bought sectors.
Europe was the sole net-bought region, but this was driven by short covering — not fresh longs. Bears were taking profit, not turning bullish.
What comes next?
The tech long/short ratio has hit a historical extreme; short positioning is heavily concentrated.
This means → if upcoming fundamentals or macro data provide a new bullish catalyst, short covering could trigger a violent squeeze rally. Without one, the current short-heavy structure will continue to weigh on individual stock performance.
In plain terms = the spring is compressed to its limit — it either snaps back hard or gets pushed further down. A middle ground is difficult to sustain.
