Goldman Sachs' TMT trading desk points out that the implied weekly volatility of US stocks this week is about 89 basis points, the lowest level in about 5 years, with its VIX index at only 0.36/10. Meanwhile, Goldman Sachs estimates that option market makers currently hold approximately $15 billion in positive Gamma hedging positions, at the 99th percentile historically. These positions tend to make market makers sell when the market rises and buy when it falls, effectively adding a shock absorber to short-term volatility. The report also estimates that 96% of S&P 500 companies have entered the stock buyback window, with announced buyback authorizations exceeding $1 trillion. Corporate buyback demand may also help absorb selling pressure in the summer's thin liquidity environment. Currently, long-term yields are still rising, and oil prices are rebounding; macroeconomic disturbances have not disappeared, but the derivatives market's pricing of short-term volatility is already very low. As long as dealer positive gamma and corporate buybacks continue to provide a buffer, short-term volatility in US stocks may continue to be suppressed; if these two layers of support weaken, the extremely low volatility itself will also increase the sensitivity to price re-amplification.
