WisdomTree launched in 2006. They now offer 78 ETFs with AUM totaling $39B. I first learned of them through Jeremy Schwartz, whom I met briefly thanks to Wesley Gray at one of AlphaArchitect’s Democratizing Quant conferences and again at #MFTF last year. Jeremy’s title is Executive Vice President, Global Head of Research. I’ve always found him thoughtful, down-to-earth and very approachable. He’s a Wharton grad, which is probably one reason the firm maintains a close relationship with famed Professor Jeremy Siegel.
