Nathan Downs: Cambridge Advisor Faced $50K Complaint

A recent, denied investor complaint against Boise, Idaho financial advisor Nathan Downs (CRD# 5833891) alleged that his conduct resulted in five-figure damages. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Cambridge Investment Research. He is also registered as an investment advisor with Duncan Financial Planning.

Mr. Downs’s BrokerCheck report discloses one investor complaint. Filed in June 2026, it alleged that as a representative of Cambridge Investment Research, he recommended an unsuitable investment in Greenbacker Renewable Energy. The complaint alleged damages of $50,000 and was denied by the firm.

In a statement included with the complaint’s disclosure, Mr. Downs offered his response to the allegations. “The investment was understood to be an illiquid private investment with risks that were fully disclosed in the offering documents, including the potential for loss of principal, limited liquidity, and the possibility that the redemption program could be modified or suspended,” he wrote in part. “Subsequent to the client’s investment, Greenbacker changed its redemption program, significantly limiting investors’ ability to redeem shares. Additionally, the investment has declined in value due to the fund’s performance and changes in the energy and regulatory landscape. These developments occurred after the investment was made and were not known or reasonably foreseeable at the time.” He also wrote that the customer reviewed the offering documents and acknowledged the risks, ultimately purchasing the investment voluntarily.

According to the Financial Industry Regulatory Authority, Nathan Downs holds 15 years of securities industry experience. Based in Boise, Idaho, he has been registered as a broker and an investment advisor with Cambridge Investment Research since 2011. He has also been registered as an investment advisor with Duncan Financial Planning since 2020. His credentials include the passage of three securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Representative Examination, or Series 7; and the Uniform Combined State Law Examination, or Series 66. He holds 28 state licenses. (Information current as of August 1, 2026.)
