In the short run, at least, the herdbehavior of the pros makes it even harder for you to take a winning bet against the "speculative element" in a stock's price.
Analysts get close to the government entities and companies under their coverage, making analysts more sympathetic to the securities they are covering. (Not to mention making it easier to miss the forest for all the trees.) Analysts also succumb to herdbehavior, meaning they are unlikely to create a forecast or reach a conclusion that is significantly different from that of their peers.
Emotional investors behave like a herd copying and replicating the behavior of one another, fearing that they will miss out on a market uptrend or be crashed in the market downtrend.
