The three-year chart reveals the riser-step pattern that has evolved over the course of the move higher. What I like about this is that the stock builds support as it climbs. If a retreat were to ensue there would be multiple ledges of support that could prevent a free fall. Make note of the support that has been provided by the 50-day moving average since January of 2013. In addition the uptrend line has remained intact as the stock has moved higher and there has been a series of higher highs and higher lows which would be interpreted as positive.
