Guy Adami, stocks editor at OptionMonster. If you're confused about stocks in this market, don't worry -- you're in good company. Consider the case of the latest analyst ratings on Goldman Sachs ( GS). In the space of 24 hours, GS was initiated with an "outperform" rating at Oppenheimer and downgraded at Keefe Bruyette to "market perform" from "outperform." Complicating things further for Oppenheimer is that its former star analyst, Meredith Whitney, had expressed a very different view of Goldman (along with the rest of the financial sector) before she broke off to start her own advisory firm in February. For the record, Whitney did say in a CNBC interview March 10 that she might buy Goldman in the $70s, though not at $100. (Goldman is trading around $96 this afternoon, though it was in the $70s at the time of her interview.) Still, as I said yesterday on "Fast Money," Oppenheimer must find it somewhat awkward to explain to clients what appears to be an abrupt change of position on Goldman. The bottom line is that contradictory opinions by analysts on any company -- real or perceived -- are bound to proliferate in this uncertain economic climate. That's why these ratings should be used as only one set of factors in evaluating a possible trade, along with the direction of options, technical trends and any other tools that are available to you. Disclosure: The writer is long on Goldman Sachs.
