Betting against Jim Cramer just became a lot easier with the launch of a new ETF that shorts the TV host's stock picks

The Inverse Cramer ETF is an actively managed portfolio that carries an equally-weighted 20-50 names, Tuttle told Bloomberg, with the product having an expense ratio of 1.2%. Essentially, Tuttle and a few colleagues track the stocks by watching Cramer's on-air CNBC appearances and routinely sift through his social media.

"If [Cramer] specifically says either buy, buy, buy a stock, then we're gonna go short that stock at the next practical moment," Tuttle told Bloomberg's Trillions podcast, referring to the product's investment strategy. "If he tells you he hates a stock or sell, sell, sell or something like that, then we're gonna go long that name again at the next kind of practical entry point."
