Hedge Fund Highlights
AQR Capital Management, founded by Cliff Asness, sharply increased its Equifax position last quarter, boosting its stake by roughly 956% to about $84M value. The size of the increase suggests the firm may be responding to valuation or factor signals rather than making a broad directional bet.
Adage Capital Partners, led by Robert Atchinson and Phillip Gross, raised its Equifax holdings by about 20%, bringing the position to roughly $29M value. The move may reflect continued interest in Equifax’s data and analytics platform following recent share price volatility.
Dimensional Fund Advisors, founded by David Booth, increased its stake by nearly 20%, now holding approximately $212M value of Equifax shares. Given Dimensional’s systematic approach, the increase appears tied to portfolio construction factors rather than short term sentiment.
Olstein Capital Management, run by Robert Olstein, lifted its Equifax position by roughly 20% to about $5M value. While smaller in absolute terms, the increase still stands out as incremental conviction during a choppy period for the stock.

What the Ownership & Insider Trade Data Tell Us
Equifax’s ownership remains anchored by large passive institutions, helping support long term stability. At the same time, hedge fund and active manager positioning appears mixed, pointing to differing views on valuation following recent stock volatility.
Insider activity appears cautious, with selling outweighing buying, though the overall impact on ownership is limited. Some trades look incremental and timing related, though that cannot be confirmed. For investors, the combined picture suggests Equifax continues to command institutional support, but both insiders and active managers appear selective as the company works through earnings growth expectations and execution across its data and analytics businesses.
