Equity Options

Options are possibly the most powerful of all derivatives. The purchaser of an option contract losses are limited to the premium paid. They are optional for the buyer but binding for the seller - Options convey the right, but not the obligation, to engage in a future transaction on a futures contract at a guaranteed price. Options are traded by both retail and institutional investors.
