All stocks go thru 4 stages, sometimes each stage can last months or even years, and it's not always easy to recognize like it is on this chart.
Stage 1: Accumulation - buyers coming in stopping the down fall, and the stock starts trading sideways. (Wait)
Stage 2: Markup - Bullish phase, where traders and institutions start buying the up trend. (Buy)
Stage 3: Distribution - where institutions and traders start taking profits - selling. (Sell)
Stage 4: Decline - shorts recognize this stage and start shorting the stock. (Avoid)
