True or false: 1. For both sides of the put option, when the market price is equal to the sum of the exercise price and the option fee, the breakeven point is reached.

Error, reason: when buying a put option, the buyer's profit and loss should be the strike price-market price-premium.

That is, when breakeven, market price = execution price-royalty.

For example, the put option contract price (strike price 10 yuan), the option fee 2 yuan, and after a period of time, the spot price 8 yuan.

Since the spot price has fallen, the contract should be executed (I will fall if I buy it), whether it is a loss or not. The formula for calculating profit and loss should be: strike price-spot price-option fee.
