Is Cambridge Investment Research a Fiduciary? What Its Own Form CRS Says (2026)

Guides › Financial Advisor Fees

Updated September 18, 2026. Quick answer: Yes, on every account. Cambridge Investment Research’s advisory service is run by Cambridge Investment Research Advisors, Inc., which is registered with the SEC as an investment adviser and is not a broker-dealer, so the Investment Advisers Act of 1940 requires it to act as your fiduciary there. A separate firm in the same corporate family, Cambridge Investment Research, Inc. (CRD 39543), is an active FINRA member broker-dealer that the Advisers Act fiduciary standard does not cover. Its own Form CRS states: “When we act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours.”

How it’s registered

From Form CRS (Client Relationship Summary) (June 2020): “Cambridge Investment Research Advisors, Inc. (“CIRA”) is registered with the Securities and Exchange Commission (“SEC”) as an investment adviser.”

Cambridge Investment Research Advisors, Inc. is registered with the SEC only as an investment adviser and its own current Form CRS discloses no commissions for its advisory services. A separately registered affiliate, Cambridge Investment Research, Inc., is the broker-dealer in the family and files its own, different Form CRS.

The standard of conduct, in its own words

“When we act as your investment adviser, we have to act in your best interest and not put our interest ahead of yours.”

On commissions: “You will pay a fee for our services based upon the type of service you receive. This can include asset-based fees, fixed fees, hourly fees, set-up fees and program fees.”

What this means for what you pay

Fiduciary status is one input, not the whole picture. Cambridge Investment Research discloses a published fee that runs up to $11,250 a year on a $500,000 account (the published maximum, which the firm says is negotiable); see the full dollar breakdown from Cambridge Investment Research’s own fee disclosure before deciding whether the standard of conduct here changes your answer.

If the answer above changes your mind about staying, read the general mechanics of switching financial advisors, or use a dated termination letter once you decide.
