@LoLBeach, take a daily chart of the SPX, add a 200 day MA to it, zoom out to see a lot of days, then scroll back and look at some historical drops... Nov 1, 2000. Dec 7, 2001, May 14, 2008, etc. It's not a slam dunk, but it's real. Also look at the big picture... notice how bull markets tend to rebound up off the 200 for extended periods while bear markets tend to get rejected at the 200. We have been rejected at the 200 three times since last Oct.
