A lookback option uses the best or worst observed underlying price during the option life to determine payoff.
A lookback option is a type of exotic option that allows the holder to exercise the option at the most favorable price of the underlying asset during the life of the option. This feature significantly enhances the value of the option for the holder, as it minimizes downside risk and maximizes upside potential.
Fixed lookback options have a predetermined strike price and allow the option holder to compare this strike price with the asset’s prices over the life of the option, thereby exercising at the most beneficial comparison.
In floating lookback options, the strike price is determined retrospectively as either the minimum or maximum price of the underlying asset during the option’s life. For call options, the strike is set at the lowest price, and for put options, it is set at the highest price.
Consider a fixed lookback call option on stock XYZ with a strike price of $50. Over the term of the option, the stock prices vary. The holder will exercise the option based on the highest stock price observed, say $70, resulting in significant profit.
For a floating lookback put option, if the stock’s highest price during the option’s life is $85 and the current price is $60, the strike price would be set at $85, allowing the holder to sell at this highest price for a profit.
A company expecting volatile prices for crucial raw materials might use lookback options to hedge against unfavorable price movements, ensuring they can buy or sell at the best prices over a period.
Investors may employ lookback options to maximize returns during uncertain market conditions, strategically focusing on the security’s price fluctuations to benefit from the best possible exercise price.
