Whats the over / under on someone entering the inverse of what WSB does?
Pump in 2020, dump in 2021.
By a similar argument to https://danluu.com/sounds-easy/ , no one will beat Jane Street in a weekend. Jane Street's hiring standards exceeds FAANG's. This is a hiring/branding strategy. Good luck to them.
They have high hiring standard, but I suspect their 100s of smart engineers can't compete with the rest of the world.

Mathematical analysis of financial markets is more celebrated when applied to relative valuation of different assets, rather than prediction of the market. Black-scholes, for example, applied calculus with an underlying no-arbitrage assumption to create a thriving market in option pricing, by giving traders a mechanism to reduce risk and thereby reduce bid offer spreads. Same in fixed income, mortgage, and credit mar…
> relative valuation of different assets, rather than prediction of the market But isn't prediction an inherent part of valuation?
I'm sorry, if you could build a model to predict markets, why will you post in to Kaggle to get $40k in prize instead of applying this model to your own broker account?
This would be much more interesting if the features weren't anonymized. At this point this is just a widest/deepest neural net competition on some unknown bunch of features.

I actually give it 48 hours before the top 3 equals what Jane Street can do in-house on this exact same dataset. A week before the reasonable plateau is reached, and a month or so before the absolute most information is squeezed out.
I expect in a constrained environment, someone on Kaggle will beat Jane Street's solution.
I never heard of Jane street. I visited the website and saw a bunch of people crammed into an open office like chickens in a breeding factory. That is not attractive to me. Competitions like this just seem to me like a cheap way to outsource problem solving without having to pay anyone. Like bringing someone in for an interview, letting them solve your problem, and then telling them they are not a good fit while prof…
Knowing what/who Jane Street is massively changes perspective on this. They are definitely not a random shitty company that outsources their core business to some challenge. They are quite known if only for the fact they practically adopted OCaml, which is quite impressive considering their size. I highly recommend checking out some of their talks on youtube like this one: https://www.youtube.com/watch?v=gXdMFxGdako
>First place: $40,000 I'm not familiar with this area so I'm probably missing something obvious. If you have a model that outperforms the market, why on Earth would you give it away for 40k rather than use it yourself and make millions?

Do they actually produce something valuable for society, or is it just the trading profit they are after?
