Underlying Asset Performance: 00768B.TWO tracks a specific bond index. The performance of the bonds within that index directly impacts the ETF's price. Higher bond prices lead to a higher ETF price, and vice versa. Interest Rate Changes: Bond prices are inversely related to interest rates. Rising interest rates generally cause bond prices, and consequently the ETF price, to fall. Conversely, falling rates usually boost bond prices and the ETF. Credit Risk: The creditworthiness of the bond issuers within the index matters. Downgrades or perceived increased risk of default can lower bond prices and affect the ETF's value. Market Supply and Demand: General investor sentiment and trading activity surrounding the ETF also play a role. High demand can push the price above its net asset value (NAV), while heavy selling pressure can drive it below NAV. Expense Ratio: The ETF's expense ratio, which covers management and operational costs, indirectly impacts the price by reducing the overall return to investors.
