0DTE Option Traders Dampen S&P 500 Market Volatility

Zero-day to expiration (0DTE) option traders are increasingly betting that the S&P 500 Index will remain stable, a trend that is suppressing significant market swings. According to an analysis by UBS Group AG, tactical traders have shifted toward a counter-trend delta bias.

This strategy involves traders buying calls and selling puts during market declines, while selling calls and buying puts during rallies. By effectively buying low and selling high, these traders create a stabilizing effect on the index.

This behavior continues to dampen volatility despite ongoing investor concerns regarding interest rates, geopolitical tensions, and earnings related to artificial intelligence.
