This program calculates the annualized historical volatility for one or more stocks over a user-specified number of N trading days. The program uses daily closing prices in the calculations. If not specified, the program defaults to N=20 previous trading days.

The user may supply either a single ticker symbol or a cell array of ticker symbols. Using the supplied N, the program will then calculate the historical volatility for each stock.

In order to run the program, the function 'hist_stock_data.m' must be downloaded and stored in the same directory. This function may be found in my MathWorks File Exchange.
