The world's largest options expiration is approaching, with a scale of approximately $23.7 billion. Historically, such large-scale expiration days often trigger significant market volatility. The price movements before and after expiration typically exhibit a one-sided trend, potentially breaking the recent wide-range oscillation and forming a clearer directional trend. These key moments often become turning points for market sentiment, and investors should closely monitor trading volume and price breakouts during the expiration period to assess whether a trend reversal may occur.
