Something wrong at PFIE?

PFIE has lost 25% of its value in three trading days this week, falling from $1.80 to $1.35. You’d suspect at first glance that this was due to the falling price of oil. However our other stock which is helped by high oil prices, PSIX (which makes alternate fuel engines), is up in the same three trading days from $59.80 to $63.40 (up 6%). This makes me suspicious of something specific to PFIE, and I’m glad I’m out.
