About
N.R. Brayton CFA is a Massachusetts‑registered investment adviser that provides discretionary portfolio management and non‑discretionary investment advice to individuals, families, IRAs and personal or family trusts. As of December 31, 2025 the firm reported about $96.8 million in assets under management across a small number of clients and manages diversified portfolios made up mainly of publicly traded securities and cash.
The firm’s investment approach is bottom‑up and long‑term, emphasizing valuation, low turnover and tax‑aware decision making; mutual funds and ETFs are used only occasionally to gain rapid or niche exposure. Portfolios are generally long‑only but the adviser discloses occasional use of long put options for downside hedging and a preference for investment‑grade fixed income held to maturity when appropriate.
What is noteworthy for a firm of this type is a regulatory disclosure: the firm consented to an order by the Massachusetts Securities Division dated April 30, 2018 related to custody of a family trust and a $5,000 assessment, and subsequently retained Wolf & Co. to perform annual surprise independent custody audits (with Form ADV‑E filings). The firm also concentrates custodial relationships at a single institutional custodian and explicitly discloses the use of derivatives in separately managed accounts, practices that are uncommon among independent peers.
