Barry Ritholtz haas a great piece on Bloomberg.com about how active management is failing to keep up, much less beat passive management. I’ve often wondered having spent about 20 years trying to produce as much alpha as possible in a short amount of time (AKA trading) if there is less alpha to be created now that everyone has instantaneous access to the same information.
There was a time when having a Bloomberg terminal presented opportunities to make very easy profits just by receiving news before other traders, but since Regulation FD and Yahoo Finance those opportunities no longer exist.
Internet has leveled the playing field: How much information that once was the province of a select few is now in the hands of all?It was a huge game-changer when Yahoo message boards begin to fill up with posts from people doing legwork on individual companies. When someone reported that XYZ Tech’s employee parking lots were filled with cars 24/7 — including weekends — anyone paying attention understood that business was booming and that sales were going to beat investor expectations. For the few who grasped that, this was a period of large trading profits.This advantage exists only when a small number of people know what a large number of people are going to find out too late to act on. When everyone knows, the advantage disappears.
