I have searched far and wide for a good definition of portfolio historical relative volatility. I started by looking at the standard mathematical definition of volatility and proceeded to research and analyze Beta, modified Sharpe, Sortino and Treynor ratios and the daily historical volatility that they measure for various mutual funds. After playing around with these and several other definitions from Modern and Post Modern Portfolio Theories I came to the realization that none of these measures, no matter how sophisticated and computationally intensive, gave me what I was really after.
I was talking to a friend a few days ago and he mentioned that CNN Money had just published Fortune Magazine's list of the best stock picks for 2008. He asked what my thoughts were, so I took a quick look at the list and jotted down my immediate responses, which I forwarded to him. Perhaps others could also benefit at looking at the other side of the coin for many of the Fortune list's companies. Please keep in mind that I did not do in depth research on any of these stocks and that such research would be warranted before making any actual buy and sell decisions.
