Jennifer Piorko Mitchell Office of the Corporate Secretary FINRA 1735 K Street, NW Washington, DC 20006-1506 To Whom It May Concern, Hi there. I’m Dave Nadig, Financial Futurist for ETF Trends and ETF Database. For most of the last 25 years, my job has been to help asset managers understand investors and help investors understand the products that asset managers build. Since 1993, I’ve been in and around the regulatory framework for ETFs – arguably the most egalitarian financial product ever created.
