Alastair Reid of Bereneberg earlier this week initiated coverage of Thomson Reuters Corp with a Sell rating and $37 price target under the belief it's hard for the company to "live up to high expectations."Reid acknowledged Thomson Reuters is very much a "high-quality company" with a "resilient" revenue stream from the high-end corporate market. However, the analyst believes that after a long period of a strong performance in the stock, the risks are now skewed to the downside.Ironically, the company's biggest rival, the Bloomberg terminal, is also showing signs of a shrinking user base.Source
