Explanation
A put option is a contract that gives the buyer the right, but not the obligation, to sell an underlying stock at a specified price (the strike price) within a specified time period (the expiration date). The seller of a put option is obligated to buy the stock if the buyer exercises the option. Patrick can purchase put options for the fund's existing assets, which means he can lock in a minimum selling price for his stocks in case the market value drops below the strike price. This way, he can protect against potential losses and hedge his portfolio against market risk.
