It does seem odd. Almost everyone who they hire (in these roles) can code. If you are just hiring traders, why not hire guys who can...you know...trade? Rather than some random person from MIT. The precise competitive advantage of JS is their tech.
I will say this another way...back in the early 2000s, investment banks used to hire people to do index arbs, the strat was literally press sell/buy button on Excel that will execute basket cash trades against an index, call our broker up on the floor and sell/buy futures...that was it. The strong implication is that JS is hiring people to do that kind of thing...investment banks stopped hiring these guys by the mid-2000s. The idea of the "maverick trader" who is just very creative doesn't really exist...almost all of those people who do that at hedge funds spent decades at investment banks where they had access to flow...and most of those people never graduated to hedge funds in the 2000s and just became execution traders. Again, JS is hiring these people out of college...that is weird. That is exceptionally weird. No hedge fund does this. No investment bank does this. No-one does this. A few trading houses do this (not many, Optiver is the only one left afaik...there used to be more, most went bust) but it is counter to the image that JS presents. As someone who knows a little about trading, this struck me immediately as extremely odd. Looking at their job listings...yes, it is odd (they have a job listing for traders: it says you should know how to program in at least one language).
Okay, the guy from Wintermute (who presumably knows something about trading) said he assumed they were doing something clever and was shocked when they failed. Also, they did a YouTube video which explained what some of the stuff they were doing was, that wasn't exactly surprising but I think people assumed (reasonably) they had more edge than they did (the reason they didn't was because they were cheating, nothing else).
Right, I think the current view is: they probably went bust in June/July (or whenever the earlier crash was), and some of the numbers they told other people about how much they made may have been fictional (I have read that they were losing money before they went bust but other people have said, again the Wintermute CEO, that they assumed FTX were making money because of what they were seeing in markets...again though, they were doing things that were obviously illegal so they were clearly making money from other things after Japan).
