I have been seeing a lot of LinkedIn endorsements of late. An “endorsement”, similar to a “recommendation” is considered a testimonial. The SEC Advertising Rule prohibits an investment adviser from using any advertisement that refers to any testimonial concerning the investment adviser or any advice, analysis, report, or other service rendered by the investment adviser.
Therefore, it is recommended that you say “no” to any endorsements or recommendations on LinkedIn.
Also, now would be a good time to update your Compliance Manual to include these prohibitions.
