Viewpoint: US Stock Market Single Stock Dispersion at High Levels, Caution Needed on Semiconductor Sector Pullback Risk

BlockBeats News, July 1st, Mott Capital Management founder Michael Kramer stated that despite the continuous rise of the S&P 500 Index, the market's internal structure is showing significant divergence, especially as the potential risks in the tech sector are accumulating. The prominent feature of the current market is the severe divergence in individual stock performance. Taking tech stocks as an example, Meta's stock price is approaching a 52-week low, while Micron Technology and AMD have seen significant gains. This "one rises, the other falls" dispersion implies that the rise of a few stocks is masking overall index fluctuations, making the market appear more stable than it actually is. The S&P 500's stock dispersion index is currently at a high level, historically seen only at higher levels during the March 2020 pandemic crash and the "Tariff Shock" period in April 2025.

The volatility indicators also show similar signals. The Cboe Volatility Index VIX is currently around 17, in a relatively moderate range; but the VIXEQ, which measures individual stock volatility, is close to 46, at a historical high. The gap between the two has widened to the most significant level since 2015, indicating that market risk has not dissipated but has shifted from the index level to the individual stock level. Meanwhile, the three-month implied correlation index is below 10, showing weak inter-stock correlations. In the event of a sudden incident, the market may rapidly reprice risk.

Kramer believes that the sectors with the highest implied volatility will be hit the hardest, with the semiconductor industry being particularly alarming. Since the end of March 2026, both Micron and AMD stock prices have more than doubled, AI-related spending expectations continue to rise, valuations are rapidly expanding, and options trading activity is at market highs. The Cboe Semiconductor ETF volatility index is approximately double that of the Russell 2000 Index and the Nasdaq 100 Index, and more than three times that of the S&P 500 Index, showing that the risk in this sector is significantly higher than the broader market.
