FVC is a momentum-based sector rotation ETF with a few twists. Its fund-of-funds structure pulls from a pool of First Trust sector and industry ETFs, both U.S. and global in scope. (Non-sector funds with significant sector overweights are also in bounds.) As such, the underlying ETFs use multi-factor stock selection and weighting, driven by growth and value factors. The ETFs themselves are selected by price momentum: The Dorsey Wright relative strength model picks the 5 ETFs with the strongest momentum and equally weights them. However, the momentum model also considers a cash index, and if a third of the ETFs in the universe start to fare worse than cash, the fund allocates to T-bills. The cash allocation can vary from 0 to 95%, although it caps any single move at the fortnightly rebalance to 33%.
