Consider following listing of call option on Tesla on Yahoo! Finance (Real quotes used). Current Price $580 Strike Price: $600 Risk-free Rate: 3.1% Time to Expiration 6 months (0.5 year) Call Premium $95.06 Dividend Yield 0% 17. What is the implied volatility of above listed call option? (hint: use the excel file I have uploaded on college. Instead of solving the algebraic equation of Black-Scholes, try to manipulate around volatility number to find the volatility that results in the given call price) 18. Above procedure of trying to guess the right number by changing the parameters of an equation is called "numerical approach" of finding an answer. Using this approach, what are the implied volatilities of Tesla using following call options prices? Strike Price Call Premium 550 $119.98 650 $78.78 $64.40 800 $42.63 900 $29.97 1000 $24.44 700 19. Plot the calculated implied volatilities on strike price - implied volatility plane and draw a graph by connecting plots. Make the horizontal axis represent "Strike Price and vertical axis "Implied Volatility".
