The VelocityShares Daily 2x VIX Short-Term ETN (TVIXF) is a leveraged exchange-traded note that seeks to provide investors with twice the daily return of the S&P 500 VIX Short-Term Futures Index. This fund is designed for investors looking to capitalize on short-term market volatility and may be suitable for those with a high risk tolerance. However, it is important to note that leveraged funds like TVIXF carry a higher level of risk and may not be suitable for all investors.
