If you go to google finance and plot the S&P 500 for all known time you get a chart that goes back to 1975. I see three big humps 2000, 2007 and 2015. This is obviously not the most sophisticated analysis, but, there seems to be a pattern were the market gets over excited and then blows off steam. Maybe we are at the start of a correction. The only thing that concerns me is that those market peaks/humps were due to humans getting concerned and changing behaviour. Maybe now that most trades are just computer to computer the Algos don't "know" to be "scared" and cool it we might keep going up till some epic event corrects it. I am hoping it's a 1-2 year correction that goes down 50-60 percent. But, who knows.
