[Interest Rate Changes]: When interest rates rise, bond yields tend to increase, causing bond prices to fall. Conversely, falling interest rates typically lead to higher bond prices.

[Credit Quality Changes]: Downgrades in the credit ratings of bonds held by the ETF can decrease their value, lowering the ETF's price. Upgrades can have the opposite effect.

[Maturity & Duration]: Longer-term bonds are generally more sensitive to interest rate changes than shorter-term bonds. ETFs holding longer-maturity bonds will experience greater price fluctuations.

[Supply & Demand]: Increased demand for the ZSB.TO ETF can drive its price up, while increased supply or selling pressure can push the price down.

[Inflation Expectations]: Rising inflation expectations can lead to higher interest rates, negatively impacting bond prices within the ETF. Lower inflation expectations can have the opposite effect.

[Market Sentiment]: Overall market sentiment and risk appetite can influence investor demand for bond ETFs. During periods of uncertainty, investors may seek the safety of bonds, increasing demand.

[Underlying Bond Market Liquidity]: The liquidity of the underlying bond market can affect the ETF's ability to track its index accurately. Illiquid markets may lead to wider spreads and price discrepancies.

[ETF Management Fees]: While fees don't directly impact the market price, higher expense ratios can reduce the overall return on investment compared to similar, lower-cost ETFs.
