Renaissance said that they put on hedge positions at the wrong time in hindsight...so they lost money on their core positions in March and lost money again as they added the hedge position in March.
not likely given that the public funds lost money on their hedge positions after March 2020...besides, how do you prove that they ripped off their public fund clients given the vastly different trade duration between Medallion and the public funds? Lots of investment firms have different strategies that saw diverged performances in 2020. In the case of Bluecrest, they were using similar strategies, and they misrepresented to clients how the actual money was managed, so it was easier to catch them...
This is entirely hypothetical. Imagine you're a public fund and you have a high-freq private fund in house. You buy XYZ hours before your public fund allocates in XYZ. Are you an nontheist? Prove that God doesn't exist.
I don't waste time on stupid semantics. if you accuse someone of illegal activity (i don't know how you can "hypothetically" accuse someone of something, but you're better at semantics than me), you gotta have at least one piece of evidence. are you the Alex Jones of ET?
Sure, they never saw a vol-line that wasn't a short. Same as PIMCO. Shorting 15% (20D) index puts. Real brainstorm over there.
