Underlying Index Performance: WSRI.TO tracks an index. The price largely reflects changes in the value of the index's constituent securities.

Supply and Demand: Higher demand tends to increase the price, while increased selling pressure can lower it.

Interest Rates: Rising interest rates can make bonds less attractive, potentially decreasing demand for bond ETFs like WSRI.TO.

Inflation: High inflation can erode the real value of fixed income, leading to price declines.

Credit Risk: Perceived increases in the credit risk of the underlying bond issuers can negatively impact the ETF's price.

Market Sentiment: General investor optimism or pessimism can influence the overall demand for ETFs, including WSRI.TO.

Liquidity: The ETF's own liquidity in the market affects its pricing, as wide bid-ask spreads can create price inefficiencies.

Management Fees & Expenses: While these are deducted from the fund's net asset value, they indirectly influence the ETF's performance and price over time.

Currency Fluctuations: Changes in currency exchange rates, particularly if the underlying bonds are denominated in a foreign currency, can affect the ETF's price.

Geopolitical Events: Major global events can trigger volatility and impact investor sentiment, leading to price swings in the ETF.

Economic Data Releases: Economic indicators (e.g., GDP growth, unemployment) can influence interest rate expectations and impact bond prices.

Central Bank Policies: Actions by central banks, such as changes to monetary policy or quantitative easing, can significantly affect bond yields and ETF prices.
