TGS is famously secretive. They went prop in the early 90s; no external investors. You won't find their returns anywhere.

The only public data available (that I know of) is related to their charitable giving.

No public data in recent years but if you dig a little deeper you can find bits and pieces here and there about their past. Not sure what name they trade under these days because I can't even find a 13-F.
