This ETN was delisted after the close on April 12, 2018, and now trades over-the-counter on the pink sheets. As a result, shareholders should anticipate ultra-wide spreads, minimal trading volumes, and prices well above or below NAVs. JJU tracks an index of aluminum futures that rolls into every other contract. Contracts are tracked starting two months from maturity and held until shortly before expiration. That differs from our segment benchmark, which follows a front-month strategy. JJU is the cheaper of the two ETPs tracking aluminum futures (JJU`s pricier sibling, FOIL, uses an algorithm to select the contract least affected by contango). However, with a near complete lack of investor interest, JJU will be very expensive to trade, raising all-in costs. Furthermore, there is a serious risk of closure (ETNs rarely close outright, but may be de-listed by the issuer). JJU is an unsecured liability of the issuer, Barclays.
