35 firms show reported AUM changes in September 18–20 observations

The observation window from September 18 to September 20, 2026, includes 35 firms with verified differences in reported regulatory assets under management. These observations track shifts in Form ADV filings. They reflect reported figures at specific moments and do not establish the timing or cause of underlying asset movements.

ADP Strategic Plan Services, LLC posted $32.4 billion in regulatory AUM in its September 18, 2026 filing. This follows a reported $23.8 billion from its July 10, 2026, submission. The $8.6 billion difference marks one of the largest reported changes in the current dataset.

Research Affiliates recorded $32.2 billion in regulatory AUM as of its September 18, 2026, filing. This reflects a $4.4 billion increase over the $27.8 billion reported in the firm's previous March 26, 2026, filing. Both amounts are taken directly from regulatory disclosures.

Sharpe Advisors, LLC reported $1.2 billion in regulatory AUM following a September 17, 2026, filing. Its previous May 19, 2026, report listed its regulatory AUM as zero. A zero value in a prior filing serves as the baseline for this comparison and is not an indicator of the firm's initial report.

Summa Corp. reported regulatory AUM of $1.6 billion in its September 17, 2026, filing. The amount represents a growth of nearly $999.3 million compared to the $587.2 million reported on May 4, 2026. This comparison highlights the distinction between filing dates and the observation period.

LVM Capital Management Ltd. reported $1.6 billion in regulatory AUM, an increase from its $1.3 billion figure previously on record. Additionally, Family Office Investment Advisory LLC reported $220 million in regulatory AUM, rising from a previously reported zero.

These observations represent simple comparisons of reported regulatory AUM. The dollar differences are not intended to measure investment performance, client flows, or internal transfers. Because a percentage change is mathematically undefined when the previous reported amount is zero, those instances are noted without a percentage figure.
