Just noticed some pretty wild options activity today across a few names. Started digging into the Russell 3000 components and spotted some interesting patterns worth flagging. Anterix (ATEX) had over 3,000 contracts trading - that's roughly 56% of the stock's typical daily volume. Most of that action was concentrated in the March 2026 $45 calls, which alone saw almost 2,900 contracts move. Pretty heavy concentration for ATEX if you ask me. Then there's UnitedHealth Group, which absolutely dominated the options board with nearly 50,000 contracts. We're talking about 5 million shares worth of activity - over half the average daily volume. The $300 calls expiring in March were the main focus there, drawing about 6,500 contracts. And LNG wasn't far behind either. Cheniere Energy saw close to 10,000 contracts with similar volume intensity - about 53% of normal daily trading. Their March $240 puts were the heavy hitters, accounting for over 2,000 contracts on their own. What's interesting is how concentrated these bets are in specific strikes and expirations. When you see this kind of clustering in options flow, it usually signals some institutional positioning or hedging activity. Worth keeping an eye on these three if you're monitoring unusual derivatives action.
