DOCU highlights the inherent risk in this market and is yet another names that has succumbed to my 50/80 Rule, which states: Once a market leader puts in a secular top, there’s a 50 percent chance that it will decline by 80 percent—and an 80 percent chance it will decline by 50 percent.

Investors could have avoided this carnage if they adhered to my simple rule: avoid all stocks below the 200-day moving average and only buy stocks in a Stage 2 uptrend.
