What Is an Option? Calls, Puts, and the Premium
An option is the right but not the obligation to buy or sell at a fixed strike. Calls, puts, the premium, and why the buyer loss is capped.
A short animated lesson introducing options for FIN301 Derivatives students at Western Sydney University, and for anyone meeting options for the first time. An option is a contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a fixed strike price on or before expiry.
The buyer pays a premium to the writer, who takes on the matching obligation. Calls grant the right to buy, puts grant the right to sell, and the maximum loss to the buyer is capped at the premium while the writer accepts a one-sided risk. That asymmetry is what separates options from futures, where both sides face symmetric obligations.
