Separately, TheStreet Ratings team rates WESCO AIRCRAFT HOLDINGS INC as a Buy with a ratings score of B-. TheStreet Ratings Team has this to say about their recommendation:
"We rate WESCO AIRCRAFT HOLDINGS INC (WAIR) a BUY. This is driven by a number of strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, good cash flow from operations, growth in earnings per share and increase in net income. We feel these strengths outweigh the fact that the company has had lackluster performance in the stock itself."
