Hello Venkat,

I calculated the coefficient of variation as the standard deviation divided by the mean. As for significance...my post was written to focus on the market's discounting ability from a discounted cash flow perspective, and not from a statistical significance point of view. After all, there is only one company being evaluated, as opposed to many so the sample size is small. I was using the coefficient of variation as a "quick-and-easy" way of showing how wildly Dell's valuation fluctuates.

With smiles,

Jason
