A levered product is not a buy and hold ETF, it is a short-term hedge for a sophisticated trader. Leveraged funds are associated with a well known phenomenon of leveraged-induced decay. To illustrate this phenomenon the US Natural Gas Fund was up 15% between April 2016 and April 2017, but it’s triple velocity product was down 12%. This principle applies to all triple velocity products. So unless you are a sophisticated day trader that requires these huge daily swings Triple Velocity products should be avoided like the plague.
