About

ConvexBeta provides discretionary and non‑discretionary portfolio management for individual investors, trusts, IRAs, and small businesses, delivering equity, fixed‑income, and blended strategies. The firm emphasizes tax‑efficient investment counsel and coordinates with clients’ tax, accounting, and estate‑planning advisors when developing plans.

The firm uses an active, tax‑aware investment process that combines top‑down strategic allocation with bottom‑up security selection, quantitative screening, tax‑loss harvesting, option collars, and the use of low‑cost ETFs and individual securities to manage costs and tax consequences. Portfolios are customized through an Investment Policy Statement created via an interview approach and are monitored and rebalanced using industry software; clients may also opt into a stock‑lending yield enhancement program through the firm’s custodian.

Noteworthy for a boutique advisor, ConvexBeta is a very small, concentrated practice (two advisors, roughly ten client relationships and modest AUM) that nonetheless draws on senior management experience at institutional and public‑sector levels, including oversight of municipal and public‑agency portfolios and roles at bank‑affiliated asset managers. That institutional background, combined with the firm’s willingness to work with trusts, small businesses, and to coordinate with other professional advisers, distinguishes its client service mix from many peers of similar size.
