Granulocytes, specifically neutrophils, help the body fight bacterial infections. The number of granulocytes in the body usually increases when there is a serious infection. People with a lower number of granulocytes are more likely to develop bad infections more often.
Congrats on a sick trade. If the buyout happens before the options expiration, you can exercise your options for stock, purchase the stock at $28.00, and sell the shares for $40.00 and make $12.00 per share (less the price of the options). Realistically, the value of the call option will go up to $12.00+ and you can just sell the option.
Investors will buy call options when they think stock prices will increase. However, investors will buy put options when they believe that the price of the underlying stock will decrease by the time of expiration. Generally, the value of an option will not vary as greatly as the underlying stock.
