How can you determine if an option is overvalued or undervalued?

To determine if an option is overvalued or undervalued, compare its market price with its intrinsic value and time value. The intrinsic value is calculated based on the difference between the underlying asset's current price and the option's strike price, while the time value considers the remaining time until expiration and implied volatility. Additionally, you can use pricing models like the Black-Scholes model to estimate the theoretical value of the option. If the market price exceeds the calculated value, the option may be overvalued; if it is lower, it may be undervalued.
