Let's check the charts.
In the daily bar chart of PLUG, below, we can see that prices made a low in late December around $1 and have subsequently soared north of $2.50 -- a huge move in less than three months.
Prices are above the bottoming 200-day moving average line and the rising 50-day line. Volume has been heavy and the daily On-Balance-Volume (OBV) line strong.
The Moving Average Convergence Divergence (MACD) oscillator is bullish. This is only a snapshot of the stock so we really need to look at a weekly chart for some perspective.
In this weekly bar chart of PLUG, below, we can see that rallies in this stock have been sharp, but definitely not long sustained.
The chart reminds me a little of my latest EKG. Prices might break above the highs of late 2017 and spike higher, but the problem is likely to be that the advance could end abruptly and you will lack the discipline to sell.
In the weekly Point and Figure chart of PLUG, below, we can see an upside price target of $4.26 being projected.
That is not a guarantee.
Bottom-line strategy: I have to agree with Jim on PLUG -- more hope than reality. Go with stocks that are more reality than hope.
Hope is not an investment strategy.
