Anybody on this thread know where one can obtain the following data:
1) Volatility figures for various stocks so as to calculate the expected value of various options using Black Scholes or other models;

2) Historical stock prices in a format suitable for spread sheets so that one can calculate volatility based on the historical trade data directly.

Someone told me that volatility data (Beta) is available on Yahoo, but I could not find it.
