Consider a European call option with a strike price of $50, expiring in 3 months. The current price of the underlying asset is $55, and the risk-free interest rate is 2% per annum. Market quotes for European call options with similar characteristics show varying premiums. An analyst uses the Black-Scholes model to derive the implied volatility of the call option based on the market price.
If the market price of the call option is observed at $7.50, what can be inferred about the implied volatility derived from the Black-Scholes model?
