HFTs came into their own over the past decade or so -- during a time of falling interest rates, unprecedented growth, and notable lack of regulation in financial markets.
One of these things is not like the other. I'd be entirely unsurprised to see most HFTs turn out like Lehman Brothers, Enron, or AIG. They all lasted more than a decade or so. But their gains were fraudulent and they failed spectacularly.
Occam's razor is all I'm saying: What's the simplest answer to the question, why aren't large HFTs with high overheads being eaten alive as technology decentralizes access to trading? Wouldn't we expect types like Burry -- self-driven, confident financial geniuses -- to be equally decentralized? Wouldn't we expect returns to become equally decentralized?
Fraud is the simplest answer. Maybe that comes in the form of market coercion, regulatory capture, negligence, or any other plain old market manipulation. Look back at Enron: The Smartest Guys in the Room. It's all much too similar for my tastes. Time will tell.
This is absurd reasoning. It's like saying Apple has such large profit margins on their iPhones that they must be either cooking their books or in cahoots with someone somewhere. It's just a phone! How hard is it for a competitor to make a comparable phone?! They've had 15 years to copy them!
> I honestly can't name any investment firm with double digit returns YoY for more than a decade or two that doesn't have bodies in the closet.
It's clear you have literally zero idea what HFT actually does, yet you don't hesitate to call them frauds. HFT firms do not "invest" like traditional investment firms or hedge funds. They provide liquidity and sometimes take liquidity but only tend to hold those positions for seconds or minutes. At the end of every day, most HFT firms have zero position (some might hold some spreads or hedged positions overnight but those are generally less risky).
> why aren't large HFTs with high overheads being eaten alive as technology decentralizes access to trading?
HFT firms don't compete against each other on pure "technology", but more so on mathematical models or what you could call intelligence. Intelligence is not simply arbitraged away over time, although it does happen to some extent. My comment earlier discusses some of this [0]. Technology has little to do with their success. By the same reasoning, why hasn't Apple's margins been eaten over time?
> Fraud is the simplest answer.
The ancient Greeks thought that Zeus was the simplest answer for lightning, but clearly we know that not to be the case.
> Time will tell.
We do not need time. We already know. That you personally don't know doesn't change the fact that nothing illegal or wrong is going on.
Enron straight up lied to regulators, many of their employees were also plain negligent. HFTs will probably find their own flavor of fraud given a few more years, if they haven't already.
This is what psychics call a "cold reading" - a statement that is bound to be true eventually! At some point in the future HFTs will "find" (?) something approximating fraud. That almost can't not be true. But I don't see how it relates to your statement that Jane Street's reported profits are fraudulent.

Point me to three funds that have maintained greater than 20% YoY profits for more than 20 years. I would be floored if you could do it. Apple, arguably the best and most profitable business in the world, manages between 20-30% YoY profit. They're the largest contributor to world financial markets rather than operating only on derivatives. I can not imagine a world in which the largest trading firms can outperform that without fraud of some kind. In my mind, it's like gravity. Little rocks rotate around bigger rocks.
