I work for a quant firm. I am not speculating, but speaking authoritatively - the effects I've stated exist, the specific examples I've given can be captured by retail, and they can deliver outsized returns. It seems mind boggling

There are plenty of known effects that are relatively simple to automate Holding overnight risk yields superior risk-adjusted returns. Buying end of month and dumping few days into new month. There are dozens of such effects These have mech

A lot of these are mostly well-meaning but have backfired. The only way an international business is going to consider investing in French workers, for example, is with relatively low salaries to offset the inability to fire them. It's

Insider trading in stocks are prohibited but not for the reason most people think. It has nothing to do with someone having an unfair advantage in an informational sense, and everything to do with fiduciary responsibility. The CEO and execu

When you are negotiating payment for any good and service, you care only what the end cost is to you. It doesn't matter how you decide to slice it - "this share you pay, this share I pay" at the end of the day it will be seen

Also it just changes the nature of the game. There's no incentive to interact with the batch until the absolute last microsecond. It will still be dominated by latency-sensitive participants, just in a manner where the difference betwe

I'd argue that it doesn't happen more because it's (relatively) easy to bring labor onshore. But yes, if that path doesn't exist, I don't think that global companies are going to start hiring American, they're

This seems virtually impossible to enforce. It's trivial to restructure hiring a developer to write software, as licensing software from a foreign development firm, or any number of other workarounds. This is not just a hypothetical, t

The assumption that companies won't offshore is doing a lot of heavy lifting. Companies already do a lot of offshoring - you think any rational actor in this space that was hiring H1Bs isn't going to simply relocate them to more f

How valid is this premise in an increasingly global world? Most of the companies that are paying salaries could (and already do!) have offices in other jurisdictions where they could hire the same talent. Better to bring this talent onshore

No, but if you gave these people extra $ to pay attention to you - on average, they would.

It's not a great video. It's basically outrage bait for people who don't understand economics, by someone who also doesn't understand economics but uses words that sound like an economist uses them.

The more retail traders, the more money that institutional traders can make! Institutional traders love the uninformed flow. It's no fun trading purely against other algorithms (and also not nearly as profitable)

Faster transaction times result in tighter spreads, as HFT firms compete each other on the price-time priority queue. HFT firms compete against each other on time, and while yes, that's a zero sum game, the end-result to the broader ma

It's kind of an open secret, but retail traders hopping onto meme stocks like DPZ and TSLA is, counterintuitively to an outsider, actually very profitable for HFTs and market makers. A good example might be - imagine you are a car deal

This looks to be a really cool project. A lot of existing profilers all seem to have different sets of limitations. The last cool profiler I looked at was Google orbit, but it's probably tangential to this project given the breadth of

Cool stuff! Do you have a public branch you're working off of? I'd love to follow the progress as I wasn't aware that qemu user emulation for BSD was even a thing. I didn't get a chance to peruse beyond briefly skimming

Yep! I have a patch to qemu based on one that never made it to master upstream. It’s a sub module in the repo

Hey, thanks for the insight - I didn’t realize this was a thing for some Nokia envs already - pretty cool! re: x86 make and shell, it probably won’t work well here because once a process tree goes to x86 land, qemu cannot see it and it can’
