About
Cornerstone Asset Advisors Inc. provides discretionary asset management and financial planning to individuals (including high‑net‑worth clients), trusts, estates, charitable organizations and business entities. The firm typically works with a small client base and generally requires an account minimum of around $1 million while offering ongoing portfolio management and tailored financial plans.
The firm’s investment process blends fundamental and technical analysis to establish asset allocation, select securities, and implement trading decisions under discretionary authority with periodic monitoring and rebalancing. In addition to standard long‑ and short‑term strategies, Cornerstone may employ derivatives in separately managed accounts—specifically option writing and spreading strategies—which is uncommon among independent, solo‑advisor firms.
As a single‑advisor practice managing a concentrated pool of client assets, Cornerstone emphasizes advisor‑led reviews conducted at least quarterly. The firm uses institutional custody and trading services provided by a major custodian and does not routinely vote client proxies, instead leaving proxy voting to clients while offering recommendations if assistance is requested.

We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor's Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and referrals are provided by FinanceHQ LLC ("FHQ"), a wholly-owned subsidiary of Warmer and an SEC-registered investment adviser. We may be compensated by participating advisors. You pay no fee to use our matching service, and advisor fees are not increased because of a referral. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
