In Western Digital (WDC) yesterday, it looks like an investor doubled up on a bullish play on the stock, as a Jan 44 – 36 call spread was sold on the storage-device-maker at 20 cents, 4000X. The activity probably rolls a position in Jan 44 calls (at $1.14) that was opened on 12/21 at 63.5 cents to a new larger position in 8000 Jan 46 calls for 47 cents each. The stock is up 2.4 percent since that time. The activity on 12/21 was rolling out of 2000 Jan 40 calls. So, after the two adjustments, the position in 2000 Jan 40 calls is now a new block of 8000 Jan 46s.
In Pfizer (PFE), there was significant call buying in the Jan 22.5, 25 and 26 strike calls.
