Historical Stock PricesNote the double quotes used in the blog are the special kind that look great in text but which won’t work in formulas. That’s it. You now have the Greeks of a call option and a put option of a stock trading at $44.83. You also have the theoretical call option price as well as the put option price. Usually, many traders will calculate historical volatility based on a period of 30 days and annualize it. If then you input that historical volatility in your calculation, then, the implied volatility is implying an annualized IV calculated based on a period of 30 days.

Despite all that I do have some stock in my portfolio but mainly special situations like closed-end bond funds and MLPs which are likely (I hope) to be valued on their earnings before the market recovers as a whole. For these purposes, I think year-end 1941 is clearly the start of that bull market; the stock market closed higher virtually every year for the next 20 years.
