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.
Normally, you'd buy to open, hope that the price goes up, then sell to close. If you thought the stock would go down, you'd do the opposite. Sell to pen first, have the stock price go down, then buy to close. You keep the difference minus commissions. Options are different and a little more complex. In options, usually you use sell to open in conjunction with a buy to open on a different option. But you could just do what's called going naked. You sell to open and buy to close a put option if you thought the stock was going up. Or you'd sell to open and buy to close a call option if you thought the stock would decrease. This is the simple definition. Trading options takes more education, so be careful if you decide to do so. Because they are leveraged, you can lose money much, much faster with options if you don't know what you're doing.
