§ 03 · THE NORTHERN SIGNAL
AC read
Northern Trust Corp's latest 13F filing reveals the extraordinary scale and active nature of this custody banking giant's operations, with $727.2 trillion in assets under management spread across an astounding 20,680 positions. The firm's 100% quarterly turnover rate and the addition of over 20,000 new positions while exiting none suggests a highly dynamic operational model that likely reflects its role as a custody provider managing assets on behalf of numerous institutional clients rather than traditional active portfolio management.
