Today’s tickers: GLW, EXPE, ODP & TSO GLW  - Corning Inc. –  A massive put spread purchased on the glass maker this afternoon appears to be the work of an investor positioning for the price of the underlying stock to decline ahead of August 2011 expiration. Corning’s shares increased 0.55% this afternoon to arrive at $22.28 by 1:40pm in New York. The price of the underlying stock has climbed more than 51.6% since August 27, 2010, to touch a 52-week high of $23.43 just last Friday. The large bearish stance employed in Corning put options today is perhaps a sign that at least one player believes the next six months may not be as fruitful for GLW investors as the last six. The trader purchased 28,000 puts at the August $22 strike for a premium of $1.83 each, and sold the same number of puts at the lower August $18 strike at a premium of $0.56 apiece. Net premium required to buy the spread amounts to $1.27 per contract, thus positioning the investor to profit should Corning’s shares drop 7.0% from the current price of $22.28 to breach the effective breakeven point on the downside at $20.37 by August expiration day. Maximum potential profits of $2.73 pad the put player’s wallet in the event that shares in GLW plummet 19.2% to trade below $18.00 before the contracts expire in August. Corning’s shares last traded below $18.00 back on December 1, 2010.
