The cluster shows a clear split: active quant funds (Millennium, Walleye Trading) accumulated while other quants (Point72, Optiver) exited. Monitor upcoming Q3 2026 13F filings to see if the buying or selling trend continued, and watch for any earnings or credit events that could explain the divergence.
Executive Summary
In Q2 2026, 20 institutions accumulated $76.9M in Banco Santander (SAN) while 16 reduced holdings by $58.6M, resulting in a mixed net conviction.
