As the saying goes, hind sight is 20/20. As the SM reached another all time high and with the majority of people here posting short signals, I thought it would be good for us to revisit what happened back in 2007 when the SPX made a double top and rolled over into what is now known as the Great Recession. Were there warning signs? I found a bunch which in the daily course of swing trading would have told me to get out. With these in mind, I like to investigate the SPX chart for the same turning signals and crossovers.
