This chart was solely for a historical visual for the S&P 500. As I look at the technicals for indications for previous reversals, I do not find anything solid. However, I am well aware of the hysteria that was around for the .COM & Housing Market Crash. This leads me to believe that, even in this market today, a reversal will have to be driven by a possible variety of: quantitive tightening, insolvency of banks, trade wars, etc.
