The financial markets are currently exhibiting a historically rare split, presenting two distinctly different worlds within the U.S. stock market.
At the index level, the S&P 500 continues to advance steadily, with market volatility dropping to its lowest point since January of this year. On Thursday, the CBOE Volatility Index (VIX) stood at 15.6, a stark contrast to its peak of 35 in March, which was driven by geopolitical concerns and market turbulence.
However, individual stock trading tells a different story: price swings have been relentless, with volatility in the technology sector intensifying notably. The CBOE S&P 500 Implied Correlation Index (VIXEQ), which measures the volatility of index components weighted by market capitalization, is currently at a one-year high. The gap between this index and the VIX has reached its widest since the exchange began tracking individual stock statistics in January 2023.
Mandy Xu, Head of Derivatives Market Intelligence at CBOE, noted via email: "The most striking feature of the current market is the stability of the major indices juxtaposed with individual stock volatility nearing annual highs. Trading focus has shifted from macro risks like those in Iran to stock-specific drivers such as artificial intelligence and corporate earnings, leading to increased divergence among individual stocks and sector correlations hitting historic lows."
This disparity in volatility between individual stocks and the broader indices significantly impacts options traders, who rely on rapid price changes in options contracts to assess risk-reward and formulate trading strategies. The semiconductor sector serves as a prime example: the implied volatility of the VanEck Semiconductor ETF (SMH) is approximately 50%, close to its one-year peak and more than triple that of the S&P 500. For individual stocks like Micron Technology, implied volatility soars as high as 101%, far exceeding that of the ETF.
Consequently, options trading volume in the semiconductor sector has surged dramatically. Scott Rubner, Head of Equity and Equity Derivatives Strategy at Castle Securities, reported that the total premium volume for semiconductor options tracked by his firm is 25% higher than the historical peak in March 2024 and five times the monthly historical average.
There are currently no signs indicating a reversal in this polarized volatility pattern. Retail investors are keen on purchasing high-priced individual stock options, betting on continued price increases, a strategy that has largely proven effective so far. In index products like the SPDR S&P 500 ETF Trust (SPY), the most prevalent trade on Thursday was selling put options, essentially wagering on a further decline in the VIX. Market sentiment for the Semiconductor ETF (SMH) lies between these extremes, with put option purchases reaching record highs.
Noel Smith, Chief Investment Officer at Convex Asset Management, stated in a phone interview: "When the market experiences such a historic divergence, the pattern typically converges gradually over time. A broad market crash is unlikely until major new listings like SpaceX and Ansop complete their IPOs and are fully absorbed by the market."
