The options expiration (OPEX) week ending May 16, 2025, is attracting significant attention from traders and market analysts due to its potential to cause notable market volatility. Approximately 34.9% of all S&P 500 (SPX) gamma is set to roll off this Friday, which could impact market sentiment and trigger unexpected price movements. Market participants are closely monitoring the FX option expiries scheduled for May 14, 15, and 16, 2025, around the 10 a.m. New York cut. Analysts and trading platforms like SpotGamma have highlighted the importance of this OPEX period, offering webinars and playbooks to help investors anticipate key stock moves and macro trends. MarketWatch and CNBC have both warned that this wave of options expirations could potentially disrupt the ongoing historic stock market rally, leading to wild trading activity on Friday. The focus remains on how options flows and macroeconomic factors will shape the market dynamics during this critical expiration event.
