@Kaladin For an investor watch out when they go below the 200 day moving average and definitely bailout out on a death cross of the long term EMA.
on your PLS its the yellow line way below the last traded price as you can see its also above the blue EMA which is the 13 day- compare that with the KAR chart below it
From memory PLV had a death cross major sell signal at the time of the Irvine PFS debacle.
