It means that I think FLGT will rise in the next few days and so therefore the value of the options will rise accordingly and then I can sell them for a profit. I have no intention of holding those calls until expiration or of owning the stock.
Some background: the reason to do this is that one can "invest" less than $700 to buy a call which represents 100 shares. If I outright bought shares with $700, I'd own like nine of them. Less principal, much more leverage. If the price rebounds to, say $85, which is where it was recently, then those calls will be worth $10 or $11 (meaning, $1000 or $1100), netting a gain of about 50%. Owning stock would yield a gain of about 10%. On the other hand, if the share price remains where it is or drops, then the calls will be nearly worthless.
