How about a more useful index than the Dow, which fails to account for basic stuff like market cap? S&P 500 % drop or something would be more meaningful.
EDIT: The page in question lists it actually, S&P 500 down 4.1%.
The correlation between the indexes is pretty strong. Despite the DOW not being a statistically great thing, it's very rare it's doing something significantly different than the S&P 500.
