Economic Growth: Strong economic growth might increase inflation expectations and lead to higher interest rates, which could negatively affect bond prices.

Fund Flows: Large redemptions from UNVB.DU may force the fund to sell assets, potentially depressing the price, while significant inflows can increase demand.

Liquidity of Underlying Bonds: Difficulty trading the underlying bonds held by UNVB.DU can create price volatility and widen the bid-ask spread.
