The Medallion is a short term daytrading/swing trading quant fund. The public fund is long term position trading/investing. That tells me their models are only good with short term signals not long term ones.
Medallion = mean reversion trades public funds = trend following trades Trend followers got whipsawed in 2020. Mean reversion did really well. It's not a matter of models being good or not.
Medallion might have taken advantage of the public funds as they entered/exited positions, but hard to reconcile the big discrepancy in 2020 performance between the two with this nefarious explanation. Most of the difference in performance is probably attributable to the difference in strategies.
The public funds are absolutely Medallion's liquidity provider. Biggest scandal in the history of the industry.
Did public funds exit 4/2020? Most of the down move came from overnight futures, so I wonder who is actually selling.
