A CRPC® is meeting with a new retirement planning client.
The advisor recommends a specific managed mutual fund that aligns with the client's risk tolerance.
However, a nearly identical, lower-cost index fund (ETF) exists that would also meet the client's objectives.
The managed fund pays the advisor's firm a 12b-1 fee, while the ETF does not.
Under the fiduciary duty of loyalty, what is the primary ethical issue in this situation?
