Continuing the speculation, they could be just "picking" the stocks after the fact when the returns are already known, iff there is no external record of their positions and transactions

There is an external record, 13F filings. Every quarter funds above a certain AUM have to disclose to the public their top long equity holdings. I’ve personally analyzed these holdings at my old quant job, they definately trade.
