TheStreet Ratings team rates AVG TECHNOLOGIES NV as a Hold with a ratings score of C. The team has this to say about their recommendation:
"We rate AVG TECHNOLOGIES NV (AVG) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its notable return on equity, solid stock price performance and revenue growth. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, generally higher debt management risk and weak operating cash flow."
