Thanks as usual to Doug Short for the great comparison of four terrible bear markets. If you can't read the key, the gray line is stocks after the 1929 crash; the red is the 1970s plunge; and the green is the collpase of the tech bubble after March 2000. The blue is now: The S&P 500 down 30 percent from its peak is better than the S&P 500 down almost 60 percent from its peak.
