Unusual Options Volume Spikes in UnitedHealth and Jabil

Trading data from April 17 reveals a surge in options volume for several Russell 3000 components, most notably UnitedHealth Group (UNH) and Jabil Inc (JBL). The spike in activity suggests institutional positioning or speculative bets ahead of near-term price movements, as volumes for both companies significantly eclipsed their 30-day averages. UnitedHealth Group saw 128,091 contracts trade, representing approximately 12.8 million underlying shares. This volume is 135.9% of the company's average daily trading volume of 9.4 million shares. Traders showed particular interest in the $325 strike call options expiring April 17, 2026, with 9,185 contracts changing hands. Simultaneously, Jabil Inc experienced options volume of 14,465 contracts, equivalent to 1.4 million shares. This represents 132.8% of its monthly average daily volume of 1.1 million shares. The most active contracts were the $295 strike put options expiring April 24, 2026, with 2,744 contracts traded. While high options volume can precede volatility, these movements are isolated to specific strikes and expirations. The divergent nature of the trades—bullish calls for UNH and bearish puts for JBL—indicates stock-specific sentiment rather than a broader sector trend.
