Spotted some interesting options action today across a few names worth keeping tabs on. ATEX has been drawing serious attention with nearly 3,000 option contracts trading - that's over half the stock's typical daily volume right there. The $45 call expiring in March was absolutely the focal point, pulling in almost 2,900 contracts on its own. Honestly didn't expect to see that kind of concentrated activity on ATEX.

Meanwhile, UnitedHealth is showing typical institutional-sized flow with around 50k contracts moving through. We're talking 5 million shares worth of options activity - pretty substantial compared to their normal daily volume. The $300 call for March has been the main event there, which tracks given where the stock has been trading.

LNG rounded out the notable movers with about 10k contracts, though the action there skewed defensive with heavy put volume on the $240 strike. That's the kind of hedging activity you see when people are thinking about downside protection.

All three showing that mix of call buying and put hedging that usually means traders are pricing in some volatility ahead. Nothing shocking, but definitely worth noting if you're watching these names.
