Call me old-fashioned, but I’m a firm believer in everyone playing their roles within the ETF space. As I mentioned in my previous blog, when ETF issuers get involved in other areas of the business — whether it’s trading or indexing — investors will likely find their interests come secondary in business decisions. Simply put, self-indexing allows for ETF issuers to make compromises that may not fall in line with best practices within the index space.
