Investor A: "Good G-d! What is that unbearable whooshing sound?"
Investor B: "That's the stock market plummeting past us."

I guess the past six days made for a useful experiment. I had previously estimated that my portfolio had a beta of 2. If the Dow Jones were to rise 1%, my stocks should rise by twice that.
