Options Brief - 31 July 2026
Summary
On July 30, 2026, the S&P 500 index rose by 1.66% to 7,437.63, primarily driven by Microsoft, which added a record USD 450 billion in market value after reporting a 43% year-on-year growth in Azure. Despite the index's rise, the average S&P 500 member finished lower, indicating a divergence in market performance. The volatility index (VIX) fell significantly, suggesting a reduction in market anxiety.
Market Overview
The market displayed mixed signals with the VIX at 17.09 and a term structure in contango. The S&P 500's equal-weighted version fell by 0.20%, contrasting with the cap-weighted index's gains. Notably, Microsoft surged by 15.5%, while Meta Platforms saw a decline of 7.95% in the same session.
Key Drivers
The primary catalyst for the market's movement was Microsoft's strong cloud performance, which led to a rebound in semiconductor stocks, snapping a six-day losing streak for the Nasdaq. The Bank of Japan maintained its interest rate at 1.00%, following a suspected intervention in the yen.
