McKesson Corp. Ratio Call Spread

A one-by-two ratio call spread initiated on McKesson Corp. (Ticker: MCK) on Monday looks for shares in the distributor of medical supplies to potentially push higher during the next couple of months. Shares in McKesson are trading lower in the final hour of trading, down 1.6% at $185.90 and near session lows as of 3:30 pm ET.
The largest trade on MCK today appears to be the purchase of 2,500 of the Aug 185.0 strike calls at a premium of $6.70 each against the sale of 5,000 of the Aug 190.0 strike calls for a premium of $3.80 apiece, resulting in a net credit to the trader of $0.90 per contract. Maximum potential gains available on the strategy (inclusive of the $0.90 net credit) amount to $5.90 per contract provided shares in McKesson rally 2.2% over the current price of $185.90 to settle at $190.00 at August expiration. Shares in McKesson last traded at $190.00 back on June 5th. The sale of twice as many of the 190.0 strike calls leaves the position vulnerable to losses on the upside in the event that shares in the name jump 5.0% to top an upper breakeven price of $195.90. The all-time high for MCK shares is $192.92.
