It is nicely written post, but I do not think that person is continuously making such return just by day-trading. It is unbelievable story of 1270%. It can be accidental one time or few times possible like GME use DeepF…Value !
For the best return, so far, Jim Simon Medallion fund alone made big strides of 80% YOY returns and that is credible. They have 300 employees share holders work on the fund, now running secret algorithm even employees do not know what it does until reports are published !
