About
Diamant Asset Management provides discretionary investment advisory and portfolio management to individuals, high‑net‑worth families, trusts, estates, and retirement plans, offering tailored asset allocation and ongoing portfolio oversight across equity and income-oriented accounts. The firm manages individual accounts directly, selecting securities, implementing strategy through mutual funds, ETFs and individual bonds or stocks, and monitoring portfolios against client objectives.
The firm follows a long‑term, buy‑and‑hold investment approach driven primarily by fundamental analysis, with technical charting used for confirmation and third‑party research from providers such as Argus and Bloomberg. Portfolios are constructed with distinct equity and fixed‑income segments (with cash grouped into the fixed‑income allocation), tax impacts considered in security selection, and an emphasis on capital preservation rather than frequent trading or leverage.
Diamant is a small, family‑owned advisor with three senior portfolio managers overseeing about $211 million for roughly 59 client relationships, and it intentionally limits the number of sizable accounts to preserve continuity of senior attention. The firm is deemed to have custody for certain trustee relationships and operates under a single‑platform relationship that supplies brokerage, custody, administrative and research services—arrangements that concentrate supervisory functions within a compact staff and that clients may want to consider when evaluating potential conflicts and operational structure.

Not sure where to start?
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 introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
