PRLB had a buyable gap up in yesterday's trade after a strong earnings report but it quickly got ahead of itself. Today, it is retracing on lower volume relative to yesterday's volume spike. Given the low of the gap up day of 46.7, if you were to buy a small position here at 50, your risk would be about 6.6%, assuming you gave the stock no room to undercut yesterday's low. If you bought a position at 49, your risk would drop to 4.7%, again with no porosity. Your risk tolerance levels will determine how much you wish to buy of PRLB and at what price level, assuming you're interest in making a buy.

PRLB earnings have skyrocketed while sales have accelerated. PRLB is involved in the hot area of 3D printing area, alongside DDD and SSYS as it makes custom parts for customers who use 3D software to design products.
