Brokerage firm BTIG has advised investors to leverage any short-term rebounds in semiconductor stocks to trim their positions, projecting a extended slump in the sector that could last into 2027. The warning comes right after an 11.4% weekly drop in the Philadelphia Semiconductor Index (SOX), marking its sharpest fall since April 2025, while the iShares Semiconductor ETF (SOXX) recorded 9 consecutive losing sessions despite remaining up nearly 64% in 2026.
Historical Data Points to Weak Relief Rallies
BTIG chief market technician Jonathan Krinsky detailed the bearish outlook in a Sunday research report, citing growing skepticism surrounding artificial intelligence valuations. "There are certainly more doubts creeping in about the AI complex of late. While those may prove to just be smoke, history suggests where there’s smoke there’s often fire," Krinsky noted.
Historical trends following a 10% or greater weekly loss in the SOX offer little reassurance for bulls. The index traded higher the following week only 43% of the time, yielding an average return of 1.7% but a median outcome of a 1.7% loss. Looking three weeks out, the index managed gains in 60% of historical instances. For risk management, BTIG highlighted $490 as crucial support for SOXX, warning that breaking below it could push the ETF toward its 200-day moving average near $468. The firm also noted that while the S&P 500 has dropped no more than 5% since June 1, 9 of its 11 sectors have suffered pullbacks of at least 9% from their highs.
Broadening Warnings Over AI Valuation Risks
BTIG’s assessment aligns with wider institutional concerns over artificial intelligence equity pricing. Earlier this month, Bridgewater founder Ray Dalio stated the AI bubble was approaching its limit, while Panmure Liberum’s Joachim Klement projected a potential breakdown in the AI trade around 2027 or 2028. The market shifts coincide with broader tech repositioning, as seen when Wall Street was gripped by AI stock bets losing millions while some strategists like Tom Lee called stock selloffs a buy setup.
On October 13, the International Monetary Fund (IMF) published its global financial stability report, listing an AI-driven market correction among three primary systemic risks. The IMF emphasized risks tied to leverage and circular financing arrangements, in which major tech hyperscalers provide funding to weaker AI companies in return for future revenue pledges.
Key Takeaways
- The Philadelphia Semiconductor Index (SOX) sank 11.4% in its worst weekly performance since April 2025.
- BTIG identifies $490 as critical support for the SOXX ETF, with risk of a drop to its $468 moving average.
- Industry leaders including Ray Dalio, Joachim Klement, and the IMF have flagged structural AI market risks through 2027.
Why It Matters
Semiconductor equities have served as the core engine of global market returns throughout the AI expansion, making a sector-wide slowdown a risk for broader equity benchmarks and risk assets alike. If historical patterns hold and relief rallies fail to sustain momentum, capital reallocation away from high-beta tech could tighten liquidity across broader markets. Investors will need to monitor whether key support levels like $490 hold or if leverage unwind in tech triggers broader systemic corrections.
