JQUA selects and ranks the companies the 1000 largest publicly traded US companies on three quality metrics: profitability, quality of earnings, and solvency. These are combined into a quality factor, which determines which securities will be included in the index and their weights. Companies are market cap-weighted using a proprietary optimization methodology that aims to match the sector weights of the Russell 1000 Index. JQUA does not constrain sector or industry exposure, so investors could experience significant portfolio tilts towards one sector or another depending on the market environment. Holdings include common stock, REITs, and preferreds. The underlying index undergoes quarterly review.
