Holocene Advisors LP and T. Rowe Price Associates Inc: where the books meet

At Q2 2026, at least 32% of the two 13F books was the same, across 201 stocks both listed, against 14% at Q4 2017. Overlap is the smaller of each shared stock’s two weights, added up: the part of one book that could be swapped for the other’s without a trade.

Only quarters both managers filed. Where either filing has more positions than are read each quarter, a stock both hold below that range is not counted, so the figure is a floor.

What the overlap is made of, Q2 2026

Stocks both listed, by the smaller of the two weights. A weight is the stock’s share of that manager’s reported book, which says how large the position is, not how strongly it is held.
