   Stock analysts have a success rate of 47% or lower for directional predictions. That's worse than a coin flip. All AI has to do is product fair 50/50 results and it can beat analysts. But you can do it too for the price of a quarter.

      I don't think analyzing just the directional correctness is enough. Magnitudes shouldn't just be ignored. A trader can still make money even if more than half of their trades were wrong directionally, and can still lose money (or even go bankrupt) even if more than half of their trades were correct directionally.
