CoStar short PUT Option Payoff at expiration

By selling CoStar's put option, the investors signal their bearish sentiment. A short position in a put option written on CoStar will generally make money when the underlying price is above the strike price. Therefore CoStar's put payoff at expiration depends on where the CoStar Stock price is relative to the put option strike price. The breakeven price of 83.75 is the critical point that divides the payoff function into two parts. Below the breakeven price, the payoff is dropping and negative (the seller makes a loss). Above the breakeven price, the payoff line is upward sloping as the option payoff increases in proportion to CoStar's price. Finally, at the strike price of 85.0, the payoff chart is constant and positive.
