The Tuttle Capital Short Innovation (SARK) was created less than 3 months ago, but in that time it’s amassed an impressive $234 million, according to data from Bloomberg detailed in an article in Financial Advisors. The young ETF has one goal: exploit the weakness in Cathie Wood’s flagship ARKK ETF by using swap contracts to short the fund. Driven by the stampede out of the kind of high-growth companies with unsure profit outlooks that are favored by Wood, SARK has posted positive inflows for 10 days straight.

Investors have proved to be very loyal to ARK, even as its outperformance of the S&P 500 dissolves, but SARK’s sustained rally might suggest that investors are starting to bet against Wood, looking for a lower-profile ETF to back. And SARK is up 22% this year while ARKK has dropped 20%. Even on the days when ARKK posts positive returns, SARK has notched inflows, noted the CEO of Tuttle Capital Management LLC, Matthew Tuttle, who believes the inflows will continue regardless of how ARKK performs in the future, he told Financial Advisors in an email. Investors view the fledgling ETF as a hedging tool, he said, and not simply as a device to take advantage of the downward spiral of the high-risk equities that Wood adores.
