Options 'Aggressively' Target Pharma Services Co.

Traders are aggressively buying calls in Omnicare ahead of its earnings report Thursday morning.

Shares of the geriatric pharmaceutical services company are falling today along with the broader markets, but its March calls are trading higher. The buying is focused on the March 30 calls, which traded more than 5,000 contracts this morning mostly for $1.05, according to OptionMonster's tracking systems.

OCR stock is down some 5 percent in midday trading to just under $27. It has been on a roller-coaster ride since its highs over $32 in September to lows under $20 in October, but the stock has been solid recently as the company declared a quarterly cash dividend earlier this month.
