Can an Option’s Extrinsic Value Ever Be Negative?

No, an option's extrinsic value (time value) can never be negative. By definition, the option premium must be greater than or equal to its intrinsic value.

If the extrinsic value were negative, the premium would be less than the intrinsic value, creating an immediate, risk-free arbitrage opportunity, which is impossible in an efficient market. The minimum value for extrinsic value is zero.
