VelocityShares Daily Inverse VIX Medium-Term ETN (ZIVZF) is an exchange-traded note issued by Credit Suisse AG that provides inverse exposure to the S&P 500 VIX Mid-Term Futures Index, seeking daily investment results of -0.5 times the performance of the index, which tracks a portfolio of VIX futures contracts with weighted average tenors of five months; it offers investors a tool for hedging volatility risk or speculating on declining market volatility over medium-term horizons. The ETN does not hold physical assets but is an unsecured debt obligation backed by the full faith and credit of Credit Suisse AG, with principal protection at maturity subject to the issuer's creditworthiness; it features automatic acceleration upon certain events like issuer default or delisting, quarterly redemption options for authorized participants, and early redemption at the investor's discretion after a specified period. Primarily targeted at sophisticated investors, traders, and institutions in the derivatives and volatility trading segments, ZIVZF operates globally on the OTC Markets with trading accessible through major U.S. brokerages. Launched in 2011 and headquartered in Zurich, Switzerland, as a product of Credit Suisse AG (now part of UBS Group following the 2023 acquisition), it experienced a significant issuer transition in 2023 when Credit Suisse was acquired by UBS Group AG, integrating its structured products into the larger entity's operations; no new product launches or major strategic shifts have been announced in the last 1-2 years, though ongoing market dynamics in volatility products continue to influence liquidity and pricing.
