He's not the only voice in finance pushing for more attention to ETFs. Charles Schwab's study noting the favor independent advisors show towards ETFs is only slightly disingenuous. Schwab is one of the most popular platforms for independent RIAs, so throwing them a bone is good marketing. It also helps that this release is timed with the rollout of Schwab's ETF-selection tool. Gotta hand it to Uncle Charlie.
Full disclosure: No position in SCHW at this time.
