Waste Management is a company that provides services which will always be in demand. This is a primary reason for the steady increase in the company's value, it generally resists market downtrends due to consistent revenue. However, it is not bulletproof. In the market crash a decade ago we saw a drop of over 50% for this stock, despite the consistent demand for its services. When you look at the Heiken Ashi chart, it is clear we are due for a red 3 month candle. The fisher is showing that the uptrend is becoming exhausted, and pretty soon long term buying will be illogical for smart money.
