Forecasts made by investment banks such as Goldman Sachs, JP Morgan and Barclays Capital are only marginally better than flipping a coin, and if you hold on to their “hot picks” longer than a few months you will almost certainly lose money, according to new research. Intertrader, a spread betting firm, examined stock predictions from so-called (and highly paid) gurus at 16 investment banks, tracked them over the following 12 months and compared them to the returns on just putting your money into a savings account or a stock market index such as the S&P 500 on Wall Street. “Investment banks’ recommendations are only marginally better than a coin flip,” says Intertrader. “The banks we looked at only managed to predict the correct direction their hot picks would go 55% of the time. And that is actually the kindest we could be – holding their predictions for longer just meant worsening results.” Investors who bought and sold an investment bank recommendation within 30 days on average made a gain of just 0.8%. If they held it for 90 days, it moved to a loss of 1.48%, while over a year the average loss from buying an investment bank recommendation was 4.79%. “We found that if you put the money you would have invested in a 3% high-interest bank account instead, your returns would generally be higher,” says Intertrader, which has created a Gurudex index that analyses investment banks. The firm says the findings serve as a reminder of Warren Buffett’s words of advice on the value of stock market forecasters: “We have long felt that the only value of stock forecasters is to make fortune-tellers look good. Even now, Charlie [Munger] and I continue to believe that short-term market forecasts are poison and should be kept locked up in a safe place, away from children and also from grownups who behave in the market like children.”
