JPMorgan warns chip stock rally to record highs risks VaR shock
JPMorgan Chase & Co. strategists warned that a rebound in semiconductor stocks to all-time highs has been accompanied by rising volatility, raising the risk of forced deleveraging by VaR-sensitive investors.
JPMorgan warned that a chip stock rebound to record highs has brought rising volatility, raising the risk of forced selling by VaR-sensitive investors.
"The risk of market tantrums is rising as sharp swings in semiconductor stocks force some investors to cut allocations," Nikolaos Panigirtzoglou, strategist at JPMorgan Chase & Co., said.
The rally to all-time highs this week has been accompanied by higher volatility, potentially triggering so-called VaR shocks for portfolios. That is a scenario where big market moves cause investors to breach their Value-at-Risk limits, requiring them to reduce positions even if they still believe in the underlying trade.
The growing presence of VaR-sensitive investors increases the market's sensitivity to self-reinforcing, volatility-driven selling, the strategists said. A sudden deleveraging in semiconductor stocks could spill over into the broader technology sector and major equity indices, potentially reversing the recent gains.
Value-at-Risk models estimate the maximum potential loss a portfolio could face over a given time frame. When realized volatility exceeds model assumptions, investors are forced to cut exposure to stay within risk limits. This creates a feedback loop: selling begets more volatility, which triggers further selling.
The Philadelphia Stock Exchange Semiconductor Index has surged to repeated records this year, driven by artificial intelligence-related demand for chips from Nvidia Corp. and other suppliers. The rapid ascent has left the sector vulnerable to sharp reversals, according to JPMorgan.
A selloff in semiconductor stocks would likely drag down the broader technology sector, which accounts for roughly 30% of the S&P 500 Index's market capitalization. The Nasdaq 100, heavily weighted toward chipmakers and AI-related companies, would face outsized pressure. Traders are watching key support levels in the SOX index and the Cboe Volatility Index, which tends to spike during periods of forced deleveraging.
The warning comes as the U.S. 10-year Treasury yield has fluctuated on shifting expectations for Federal Reserve policy, adding another layer of uncertainty for equity investors. A simultaneous spike in bond yields and equity volatility would compound pressure on multi-asset portfolios that use VaR-based risk management.
Nvidia Corp., Advanced Micro Devices Inc. and Broadcom Inc. are among the semiconductor names with the largest weighting in major indices, making them primary candidates for forced selling if VaR limits are breached. Options market activity suggests traders are already positioning for increased volatility, with put premiums on the Semiconductor ETF rising relative to calls.
