"We rate NATIONAL OILWELL VARCO INC (NOV) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, attractive valuation levels, good cash flow from operations and solid stock price performance. We feel these strengths outweigh the fact that the company has had sub par growth in net income."
