Who is making money at MM in 2020

With most MM platforms handily outperforming the market and other HFS posting double digit returns in 1H 2020, I’m curious where the bulk of the profits are coming from.

There was an FT article that reported that Citadel Global Equities (their original stock picking unit) was down 6% YTD and their Fixed Income unit up 9% YTD. Other chatter is that quant generally has been a laggard so far this year at MM.

Anyone please share if you know sub strategy level performance. From the sound of it majority of profits have been coming from stock picking units
