What is Knock-Out Option?
A knock-out option is a derivative contract in option, which loses its entire value if the price of the underlying asset reaches up to a certain level and option contract expires worthless. In such a case, the buyer does not get payoff and option writer receives fixed payoff if the price of the underlying reaches up to a certain level. Knock-out price decides the level of options contract that the buyer or seller (writer) can hold.
Stock X trading at $200 per share investor decides to buy a call option of strike $210 at with a knock-out price is $220 at $2. In plain vanilla option call option of a strike, $210 is at $5. Buyer is bullish on the stock, but have a doubt regarding price level will cross above $220. If by the expiry of that option contract price of stock reach the level of $220 then, the option contract will expire worthless, in case it does not hit $220 then the option continues to be valid until the expiry of the contract.
- Scenario 1: The stock price of X remains below $210. In this case, the Knock-out call option buyer will face a loss of $2 and regular option buyers will face a loss of $5 since the call strike becomes out of money.
- Scenario 2: The stock price of X is above $210 but not above $220. In this case, the knock-out option buyer will have more benefit since the price paid to buy a call of $210 is $2 compared to the regular option buyers.
Assume if the stock price of X by the end of options contract period is $218, then regular option buyer will get a profit of $3 ($218-$210-$5=$3) and Knockout option buyer will receive a profit of $6 ($218-$210-$2=$6)
- Scenario 3: The stock price of X crosses the level of $220, knockout option ceases to exist while regular option trader will continue to receive profit as per price.
Assume if the stock price of X is $250 then regular call option buyer of $210 at $5 will get a profit of $35 ($250-$210-$5=$35)
