A put option is a contract that gives the buyer the right, but not the obligation, to sell a certain amount of an underlying security at a specified price within a specified time frame. A put option increases in value as the price of the underlying security decreases, and vice versa. Therefore, buying a put option can be used as a hedging strategy to protect against downside risk or loss in the value of the underlying security. In this case, Maxine is using a put option to hedge against the potential drop in the market value of Never2Tacky due to the regulatory changes. If the price of Never2Tacky falls below $95, she can exercise the put option and sell her shares at $95, limiting her loss. If the price of Never2Tacky stays above $95, she can let the put option expire and keep her shares, paying only the premium for the option. Buying a put option is not speculating, as it does not involve taking a high-risk position in anticipation of a favorable outcome. It is also not related to modern portfolio theory or passive management, which are different concepts in investment analysis.
