Viewpoint: Trillions of Dollars in Options Set to Expire Will Trigger Two Weeks of Volatility in the US Stock Market

**U.S. Stocks Poised to Rise in H2 Amid Near-Term Technical Volatility: Analyst** NEW YORK, June 18 (Reuters) — Scott Ruben, Director of Stock and Equity Derivatives Strategy at Castle Securities, noted Wednesday that U.S. equities could face heightened volatility over the next two weeks, driven more by technical factors than underlying fundamental shifts. Ruben pointed to key catalysts for the upcoming swings: Starting June 19, the market will see the largest single-options expiration in history, paired with end-of-quarter pension portfolio rebalancing and position adjustment trades by top institutional investor groups. He labeled this window “one of the most critical technical stretches of the year,” emphasizing fund flows will carry far more weight than macro or company-specific fundamentals during this period. For investors, Ruben frames the coming volatility as a purely technical phenomenon, advising them to buy on any market dips. Once these two weeks wrap and the quarter closes, he expects the market to return to a significantly improved environment. Ruben also highlighted a notable shift in retail investor behavior: No longer just chasing high-risk assets, individual investors are increasingly targeting companies favored by institutional allocations and those that drive benchmark index performance. Compounding this, U.S. households hold a record level of cash, waiting to enter the market during a pullback. Ruben noted this cash deployment pattern typically only changes when the CBOE Volatility Index (VIX) climbs above 30; the current VIX hovers around 16, a relatively low level. Backed by multiple funding tailwinds, Ruben concluded the U.S. stock market will continue its upward trajectory through the second half of the year.
