For a buyer of an option, what does the premium paid represent?

The premium paid for an option represents the maximum risk that the buyer of the option is willing to take. When someone buys an option, they pay this premium upfront, which is the price for acquiring the rights that the option provides. In the event that the option expires worthless, the buyer's total loss is limited to the premium paid. This characteristic makes the premium a crucial factor in understanding the risk profile of the investment.

In essence, the premium can be thought of as the cost of entering a potential investment opportunity while limiting the maximum amount that the buyer could lose. It does not reflect profit, minimum investment, or guaranteed return, which are concepts that pertain to different aspects of financial transactions and investment strategies.
