3 of the OCT 10's had been open (haven't been listed long).
Today someone bought 1,267 or them for 1.65-1.72, that is a sizable bet!
I was looking at OCT options for myself when I noticed this. Often in the fall based on Cmas electronics news and companies scaling up stocks like KLIC can get a good bump.
I see nothing else of significance in KLIC options trading today. But there are more JUL puts traded than normal at 10 & 11.
