CMA – Comerica Inc. – The financial services firm’s shares declined as much as 4.8% today to touch down at an intraday low of $36.38. One options investor expecting Comerica’s shares to continue to head south ahead of October expiration purchased a plain-vanilla debit put spread. Shares are currently down 3.65% on the day to arrive at $36.82 just before 2:45 pm ET. The bearish player purchased 5,000 puts at the October $36 strike for an average premium of $2.05 per contract, and sold the same number of puts at the lower October $30 strike for an average premium of $0.50 apiece. The net cost of buying the spread amounts to $1.55 per contract. Thus, the investor responsible for initiating the transaction is poised to profit should CMA’s shares fall another 6.4% from the current price of $36.82 to trade below the effective breakeven point at $34.45 by expiration day. Maximum potential profits of $4.45 per contract pad the investor’s wallet if Comerica’s shares plummet 18.5% to slip beneath $30.00 by expiration in October. The surge in demand for options on the stock helped lift the overall reading of options implied volatility on CMA 9.1% to 34.00% this afternoon.
