WDC options flow nets negative $40.2M after Tuesday's 6.9% drop. Three $450 call hits and a $370 December put frame the tape.
The $450 calls repeat, the premium tally leans the other way
The most interesting print in WDC today is a cluster, not a single block. Three separate hits landed on the $450 call expiring October 23, at $0.32M, $0.17M and $0.08M, for $0.57M combined. Repeated prints in one strike and expiry usually mean a single order worked in pieces, or several participants picking the same line.
The day's net premium impact is negative $40.2M, which is bearish. The eight alerts we're tracking sum to only about $1.35M, so the bulk of that skew comes from flow below our whale threshold or from size we aren't itemizing here. The $450 calls don't explain the tape. They sit on top of it.
What the put side is saying
The largest single print on the list is a $0.45M put at the $370 strike expiring December 18. That strike is roughly 10% below Tuesday's $411.04 close, after a 6.93% drop that day. It also runs past the November 5 earnings date, so it covers the event.
A put that far out of the money with that much time is a classic hedge profile. It can be a holder buying crash protection on a name with a beta above 2. It can also be an outright bearish bet. We can't separate the two without knowing whether it traded on the bid or the ask, and the alert list doesn't settle that.
The weeklies are noise, with one exception
The October 9 contracts are small. A $385 put at $0.05M, a $387.5 put at $0.02M and a $420 call at $0.05M total $0.12M. Those are short-dated lottery tickets around the $411 spot level, not positioning.
They matter for a different reason. With the stock moving 6% to 7% a session, dealers holding these weeklies carry gamma (the rate at which their hedge delta changes) that swings sharply between $385 and $420. Small premium can still force hedge flow in either direction if spot moves through that band before Friday's expiry.
Reading the setup
Calls at $450 are about 9.5% above the close. If those hits were bought, the buyer is paying for a retrace of Tuesday's drop plus a bit more inside three weeks. If they were sold against stock, the read flips to yield harvesting into any bounce. The list gives us strike, expiry and premium, not side, so we don't know which.
The cleaner read comes from the totals. Itemized put premium is $0.52M against $0.83M of calls, yet the aggregate is deeply negative. That mismatch points to put buying or call selling elsewhere in the chain, and it argues against treating the $450 cluster as a bullish signal on its own. Our [Whale Alerts dashboard](/whalealerts) shows the side and aggressor detail for each print as it lands.
What to watch
Track the $420 and $385 strikes into Friday's October 9 expiry, where dealer hedging should be most sensitive. A close back above $441.64, Monday's close, would make the $450 October 23 calls look like a real upside position. Fresh size at $370 or a lower December strike on the ask would confirm the hedge-or-bearish read on the put side.
