Yesterday, GLW made one of the strongest upward pushes I have witnessed for a long time ! Couldn't find any news to support the buying power, but it was definitely there ! It pushed thru 1st and 2nd levels of resistance (13.01 and 13.16), but today it has pulled back to the 13 support number. Consider taking a bull put spread, buy the Oct 11, sell the Oct 13 for a credit of 0.28 and be prepared to either roll forward or be assigned.
Disclosure: I am long GLW.
