Great graphs from Bill Cara juxtaposing the 1974 and 1987 market collapses with the current one.

By the way, after being cut in half, the market put in a near term bottom on November 13, 1929.  It appears that the market, after being cut in half, put in a near-term bottom today, November 13, 2008.

Hopefully, that is where the similarities end.
