TheStreet Ratings team rates YANDEX NV as a Hold with a ratings score of C+. TheStreet Ratings Team has this to say about their recommendation:
"We rate YANDEX NV (YNDX) 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 reasonable valuation levels, expanding profit margins and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we also find weaknesses including deteriorating net income, weak operating cash flow and a generally disappointing performance in the stock itself."
