BETH is designed to provide managed exposure to the two most well-known digital assets, bitcoin and ether. It does so by investing in USD cash-settled, front-month CME bitcoin and ether futures contracts while also considering back-month contracts. The fund utilizes a market cap-weighted strategy and allocates its assets to both the cryptocurrencies in proportion to their market capitalization. Investments are made through a Cayman Islands subsidiary, capped at 25% at each quarter end. Other securities, including reverse purchase agreements may also be utilized in certain circumstances to maintain the funds desired level of exposure to assets. The bitcoin and ether future contracts are rolled each month, as they near expiration, and are cash settled based upon the CME CF Bitcoin-Dollar Reference Rate and CME CF Ether-Dollar Reference Rate, respectively. Prior to Sept. 27, 2024, the fund name was Proshares Bitcoin & Ether Market Cap Weighted Strategy ETF.
