YFYA tactically invests in other ETFs and single securities. The underlying ETFs invest in a core mix of investment-grade debt securities, government bonds, corporate bonds, preferred stock, and equity securities. The funds adviser evaluates the macroeconomic environment and market conditions to allocate among various asset classes, selecting ETFs that align with investment objectives and strategies. It employs dynamic rebalancing, adjusting allocations based on interest rate movements and market outlooks, potentially favoring short-term bonds with rising rates or longer-duration bonds with stabilizing rates. Underlying ETFs may also invest in fixed income and equity-related derivatives for hedging and return enhancement. The Strategy A ETF maintains effective duration of around one year and aims to remain fully invested, though some ETFs might concentrate assets in specific sectors or securities, retaining liquidity for redemption needs.
