Sept 30, 2014 - Cash $18m, no debt, Net Income $2m, so the company is very unlikely to go to zero. The shorts will need to cover as the stock appears to be putting in a floor.
PFIE is an oil services company which has sold off with the sector. In the summer of '14 they raised $16m at $4, and with no debt, they are well positioned to weather the storm.
Buy at $2.52 for a trade to resistance at $3.20 and re-evaluate at that time.
