Andrew Chanin, the 30-year-old founder of New York–based PureFunds, watched two of his first three ETFs fail before reaching Earth orbit. They liquidated because they couldn’t gather enough assets to cover expenses. A third fund barely made it aloft; it still has just $3.6 million in assets.
Chanin kept at it. In November, he launched the PureFunds ISE Cyber Security ETF (Symbol: HACK). By July, HACK had attracted $1.4 billion—one of the fastest ascents in ETF history. (On Aug. 25, after two days of turmoil in the market, it had $1.2 billion.)
