The market is random and unpredictable when it's random and unpredictable. And it's the opposite when it's the opposite. There will always be a small segment of traders who will do well. Doesn't mean that they are the Oracle of Delphi. It just means that, in a large enough sampling, the probability of those people existing is not zero. There is nothing in HFT that supports an argument of predictability unless you are another HFT possibly. Insider trading is a crime specifically because it removes the randomness of the market so I'm not sure why that's listed. And if there were, as you say, general predictable events then that does nothing to support the idea that Bridgewater has any special access to those.
