Sure -- Jump, Tower, HRT, Citadel all have similar results. Why do you not believe such results are possible? Do you think it's impossible for a firm to have statistically positive edge for sustained periods of time?

I assume you're referring to these guys: http://www.bloomberg.com/news/articles/2014-07-23/don-t-tell-anybody-about-this-story-on-hft-power-jump-trading http://www.bloomberg.com/news/articles/2014-07-23/don-t-tell...

  Of course, I think they're the only trading firm named Jump. Is there something particular in that article you wanted to point out?

    The article speaks for itself ... and anyway your examples are all HFTs. Of course, having an edge for a long time is possible, even essential. The entire argument here is about having a legitimate edge.

      Please be more specific, the article doesn't appear to say anything other than that Jump has no interest in talking about themselves to outsiders (and why should they? They have no customers, they have no reason to publicize themselves). I don't see anything negative in the article. My examples are HFTs because those are the firms that make the largest number of bets per day, so they have the highest chance of having a day end up being positive (law of large numbers). That's why all the top HFT firms have ~100% positive days. Do you believe that no HFT firms have a legitimate positive edge? If so, do you have any proof that e.g. Jump/Tower/HRT have an "illegitimate" edge?

        I usually like a good heated discussion on the interwebs as much as anyone, but when you say: "I don't see anything negative in the article", I realize that I'm wasting my time and I'm already bored.

        I don't see how our discussion is heated. I'm merely asking for specific examples, because reading an article about how quiet and media-averse a particular HFT firm is doesn't ring any bells in my head.
