Opinion: US Stock Market Faces High Individual Stock Dispersion, Semiconductor Sector Correction 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 clear differentiation, especially as the potential risks in the technology sector are accumulating. The prominent feature of the current market is the significant 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 substantial gains. This "rise in some, fall in others" dispersion implies that the rise in a few stocks is masking the overall index volatility, making the market appear more stable than it actually is. The S&P 500's stock dispersion index is currently at a high level, reaching a level higher than only seen during the March 2020 pandemic crash and the April 2025 "tariff shock."

The volatility index also shows similar signals. The Cboe Volatility Index VIX is currently around 17, in a relatively moderate range; however, 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 the market risk has not disappeared but has shifted from the index level to the individual stock level. Meanwhile, the three-month implied correlation index is below 10, showing weak interconnectedness between individual stocks. In the event of a sudden shock, the market may rapidly reprice risks.

Kramer believes that the sectors with the highest implied volatility will be the most affected, with the semiconductor industry being particularly worrisome. 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 elevated levels in the market. The Cboe Semiconductor ETF volatility index is approximately twice that of the Russell 2000 Index and the Nasdaq 100 Index, and more than three times that of the S&P 500 Index, indicating that the sector's risk is significantly higher than the broader market.
