lambda - Investment & Finance Definition
The ratio of the percentage change in an option’s price to the percentage change in an underlying price. Lambda measures the change in option premiums for a percentage point change in the option’s implied volatility. If lambda is high, the value of an option is very sensitive to even small changes in volatility. A low lambda means that volatility changes have little impact on the value of an option.
