Corning (GLW) shares broke to 52 week highs and more than 24,000 calls traded Friday, 4X average volume, with puts also trading 2X average volume at 9,000. The largest spread was a very bullish risk reversal in February as 8,600 of the $21 calls were bought at the 30 cent offer and 3,000 of the $18 puts were sold at $1.05, looking for a strong Q4 from the LCD screen maker. January $17.50 calls were also bought in large blocks at the offer throughout the day. Corning will present at the Barclays Tech Conference on December 9th, and the bullish February action is likely in anticipation of a February 5th Investor Meeting.
