Predictions are hard................

 

This data is fairly well known. The problem, though, is that trading activity generates revenue for the brokerage industry, so it has an interest in keeping investors engaged with the market. That’s why brokerage analysts are on TV every day, offering their forecasts for individual stocks, for the overall market and for the broader economy. To be sure, this makes for interesting television. The problem, though, is that it’s been shown to carry almost no value. According to research by Joachim Klement, the accuracy of Wall Street prognosticators is approximately zero.
