I think I have some insight.

PYR is small and about 45% of its stock is held by retail investor. This tends to make it more volatile.

At the current time sales are comprised mainly of large purchases making Q revenue "lumpy". Q3 20 was huge, Q4 down some and Q1 flat with Q4. This is partially do to accounting and nature of sales.

As 3D powder sales, maintenance and parts rev ramp this "lumpiness" will decrease. 

As earnings become more predictable institutional investors will be attracted to the stock and volatility will decrease and stock ptice will steadily increase.

I find the most difficult part of owning successful smaller companies is holding on. Experiencing a bull market in a small co. is like riding a bull. Remember people buying the PYR stock that is being sold now are more sure of PYR success than those who sold it. Shares are moving from weak hands to stronger hands.
