For those bearish on Ark Invest’s innovation-driven stock picks, there might soon be a new ETF that allows investors to bet against them.

Tuttle Capital Management, a small fund company with 10 ETFs and $228m under management, has filed to launch the Short ARKK ETF under the ticker SARK. The fund would seek to track the inverse performance of the $23bn Ark Innovation ETF through swaps contracts, according to a filing with the Securities and Exchange Commission.
