Will the Da Vinci Code be right again in calling a major market bottom? The S&P 500 fell to 666 on an intra-day basis on March 6, 2009. That devilish number marked the bottom in the previous bear market. On June 16 of this year, the S&P 500 closed at 3666, down 23.6% from its record high on January 3. That marked the bottom to date in the current bear market. The index is up 6.3% since then and down 18.7% since its January 3 peak.
