Define value. Should capital markets work? Should people be allowed to dynamically allocate capital to the most attractive companies? The argument tends to be that making a decision about buying and selling in microseconds is not providing value, but generally everyone agrees that it should be possible at some level (by minute? by hour? by day?). There are a bunch of arguments here but broadly speaking I don't see how they change the underlying game. Make good decisions on where to allocate capital, make money as the market price caches up with your prediction.
