ProShares Launches Two New Inverse Treasury ETFs

ProShares, a premier provider of alternative exchange traded funds (ETFs), today announced the launch of two new ETFs that provide inverse exposure to the U.S. Treasury market.

The ProShares UltraShort 3-7 Year Treasury (NYSE: TBZ) is the first ETF in the United States to provide inverse exposure to the 3-7 year segment of the U.S. Treasury market. TBZ seeks to provide -2x the daily performance of the Barclays Capital U.S. 3-7 Year Treasury Bond Index, before fees and expenses. The ProShares Short 7-10 Year Treasury (NYSE: TBX) seeks to provide -1x the daily performance of the Barclays Capital U.S. 7-10 Year Treasury Bond Index, before fees and expenses. Both ETFs list on NYSE Arca today.

“Our lineup of inverse bond ETFs has been extremely popular, garnering more than $7 billion of assets since launching less than three years ago,” said Michael L. Sapir, Chairman and CEO of ProShare Advisors LLC, ProShares' investment advisor. “We are pleased to add two additional ETFs to the set of tools available to investors concerned about a possible pullback in bonds.”

TBZ and TBX bring ProShares’ lineup of inverse bond ETFs to eight. Six of the eight ETFs are benchmarked to a Treasury bond index. One is benchmarked to a high yield bond index (NYSE: SJB) and one to an investment grade bond index (NYSE: IGS). SJB and IGS both launched in the past two weeks.

Leveraged and inverse ProShares and ProFunds seek returns that are multiples or inverse multiples (e.g., 2x, -2x) of the return of an index or other benchmark (target) for a single day. Due to the compounding of daily returns, leveraged and inverse ProShares’ and ProFunds’ returns over periods other than one day will likely differ in amount and possibly direction from the target return for the same period. Investors should monitor their holdings consistent with their strategies, as frequently as daily, and rebalance if necessary. A rebalancing strategy involves transaction costs and may have tax consequences.

Disclosure:

Investing involves risk, including the possible loss of principal. ProShares and ProFunds are non-diversified and entail certain risks, including risk associated with the use of derivatives (swap agreements, futures contracts and similar instruments), imperfect benchmark correlation, leverage and market price variance, all of which can increase volatility and decrease performance. Bond values will fall when interest rates rise. High yield bonds may involve greater levels of interest rate, credit, liquidity and valuation risk than for higher-rated instruments. Short and UltraShort ProShares and ProFunds should lose money when their benchmarks or indexes rise. See the prospectus for a more complete description of risks. There is no guarantee any ProShares ETF or ProFund will achieve its investment objective.
