Unusual options volume hit nine names on September 10, with Celanese and Voya seeing call volume four to five times normal

Nine names traded materially above their own typical options volume on September 10, 2026, and the split between call-side and put-side flow is the part worth reading. On the call side, Celanese saw 10,136 contracts against a typical 1,988, a 410% jump; VOYA traded 5,005 calls versus a typical 887, up 464%; SYF 4,049 calls against 1,219, up 232%; and KHC 83,191 calls versus a typical 31,365, up 165%.

Put-side activity clustered in a different set of names. APH traded 18,401 puts against a typical 8,909, up 107%; BRZE 5,672 puts versus 2,029, up 180%; York saw 6,218 puts against 2,824, up 120%; WMB 17,029 puts versus 11,080, up 54%; and LEN 7,075 puts against 6,008, a more modest 18%.

Two framing points keep this honest. Every one of these baselines is a single name measured against its own trailing average volume, not against the market or against any historical record. None of the underlying sources uses the word record, and the spread is wide: Celanese and Voya are genuinely four to five times normal, while Lennar at 18% above average is barely a signal at all. Lumping them together as one wave of activity overstates the smaller ones considerably.

The second point is about interpretation. Volume tells you contracts changed hands, not which side initiated or why. A call-volume spike can be an opening bullish position, a covered-call overwrite, or the unwinding of an existing short, and none of these sources report open-interest changes or implied volatility, which are what would distinguish them. Read these as attention rather than direction. KHC is the useful illustration: it carries the largest absolute call volume on the list while also carrying a consensus Reduce rating, which is exactly the kind of mismatch that volume alone cannot resolve.
