Karafilis Investments Corporation

Karafilis Investments Corporation provides discretionary portfolio management to individuals (including many high‑net‑worth clients), trusts, estates, and corporations, applying investment supervisory services across its client accounts. The firm reports managing about $17.3 million in client assets across a small number of active accounts and requires clients to maintain custody at the firm’s chosen custodian.

The adviser follows a diversification, low‑cost, long‑term approach grounded in Modern Portfolio Theory and asset allocation, building primarily with Dimensional Fund Advisors’ enhanced‑index mutual funds. Karafilis emphasizes multifactor, science‑based portfolio engineering (using DFA’s five‑factor model) to define risk exposures, set portfolio “style,” and limit turnover.

Compared with many peers, the firm is unusually small and long‑standing, operating as a family‑owned corporation with a concentrated advisory team and a philosophy that portfolios generally do not deviate from their established framework. It also requires custody at Charles Schwab and explicitly cites factors such as margin interest rates, prime‑broker/trade‑away arrangements, and Schwab’s institutional services when selecting a broker—practices that align with permitting borrowing or margin activity in managed accounts.
