Our very own Dani wrote a brilliant post about the Mackay Effect as revealed in the New York Times. I thought I would weigh in with my opinion…
For those of you who underestimate the power of what Mackey did in those boards, Yahoo! Finance Groups, I just spoke to my college chum and fraternity brother (Phi Kappa Psi), David, and he told me that as a young analyst one of his daily tasks was to read the boards at Yahoo!, he was not alone, there were legions who scrutinized the Yahoo! Finance Groups very carefully, looking for market indicators.
He told me that he kept track and could see these little, small, conversations either precede changes in the stock market or catalyze the selling off or buying of stocks.
There is a high concentration of influencers in these spaces and while “having fun” is fine and good, the ramifications are real, especially if “his identity was not as well hidden as he may have hoped” because that means that he was in fact revealing insider info to those people who are running Wall Street.
Seriously!
