Quote from rufus_4000:
Two comments. One, I disagree HFT is only practicable for IB desks and "hedge funds", sure it takes a certain lvl of capital investment (as you say, "Fire power") and fixed cost platform building to play in the HFT game, but it is not all that high, really. We are not talking about 100M or more, there are quite a few firms who are quite successful in HFT with 1-10M of capital. Let's face it, if you are doing 1000s of trades a day, the amt of capital you can allocate to each trade can not be gigantic by definition.
As a tangent, I do believe the media is overblowing how profitable HFT can be, and it is not just a matter of "us" (for disclosure, I run a HFT outfit) not wanting other ppl to crowd our space, it is just that the amount of capital we can deploy is really very limited. Which, of cos, makes what misha did all that more impressive. So since the capital is limited *and* the startup fixed cost is not all that high, I truly believe HFT is something that smaller firms can compete in (I certainly believe so! since this is exactly what I do on a daily basis). And frankly, what my firm is doing, is not all that "special", I have joked that our "secret sauce" can fit on a single page recipe card, and still have room left over for the baked brownie recipe. It is just how the HFT systems "model" the market, that's all.
I am going to use an overused example here, RenTech Medallion, which, by some estimates, is only about 6-7B in size. Why won't he open up Medallion to other investors, and charge a SAC like 4/50 fee? It is because the strategies have size limitations. And from RenTech launching the RIEF and RIFF, it is not that Simons thinks "he made enough", he is definitely greedy and wants more.
Second comment I will reply to nitro's comment.

You should ask the CEO of a certain HFT boutique from the Netherlands HOW profitable their "outfit" IS...
