Plug Power Inc. (PLUG) is engaged in the development of hydrogen fuel cell systems that replace conventional batteries in equipment and vehicles powered by electricity. PLUG shares have made some dramatic moves over the past 20-plus years. Let's check and see if any more drama lies ahead.
In the daily bar chart of PLUG, below, I can see that the shares have spent more time in a downtrend than the time spent in an upward trend. Rallies in March and August managed to extend above the 200-day moving average line but this current rally may actually stall at the declining 200-day line.
The trading volume shows only a slight improvement in January. The daily On-Balance-Volume (OBV) line is above the zero line but the two moving averages that comprise this indicator are on top of each other.
