short position summary
Short Call Option:
When you sell a call option, you are obligated to sell the underlying asset at the strike price if the option is exercised by the buyer.
Profit: The maximum profit is the premium received from selling the call option. The profit decreases as the price of the underlying asset rises above the strike price.
Loss: Unlimited. If the price of the underlying asset rises significantly above the strike price, the losses can be substantial.
Short Put Option:
When you sell a put option, you are obligated to buy the underlying asset at the strike price if the option is exercised by the buyer.
Profit: The maximum profit is the premium received from selling the put option. The profit decreases as the price of the underlying asset falls below the strike price.
Loss: Limited to the strike price minus the premium received. If the price of the underlying asset falls to zero, the maximum loss is the strike price.
