1. Portfolio Overview

Capstone Capital LLC presents a highly concentrated, passively managed portfolio with a distinct preference for Dimensional Fund Advisors (DFA) strategies. As of the reporting date of December 31, 2025, the total portfolio value stands at approximately $153.91 million, representing a growth of 13.0% from the previous quarter's $136.25 million. The portfolio is compact, comprising only 20 holdings, which indicates a focus on core exposure rather than broad stock picking...

The most defining characteristic of this portfolio is its heavy allocation to ETFs, which account for 97.4% of the total assets ($149.97M). The strategy appears to be a "core and satellite" approach, though the "core" is overwhelmingly dominant. The firm utilizes a small selection of individual equities to complement the primary ETF holdings, but these serve as minor satellites (less than 3% combined). The portfolio’s growth this quarter was driven by a combination of market appreciation and a significant inflow of capital, evidenced by the initiation of several new positions totaling over $12 million.
