Options are immensely powerful financial instruments. Buyers of options can hedge their portfolios, generate leveraged upside returns or simply cheaply get upside to a stock, all with limited downside. Sellers of options can generate high returns on their investments by selling both calls and puts, generating yield that is unmatched elsewhere in the world of finance. This is why options are a multi-trillion dollar market in traditional finance, with options traders often driving the movements of the stock market generally.
