Interest Rate Expectations: Expectations of future interest rate hikes by the Bank of Canada can pressure CDLB.TO's price downwards, as investors anticipate higher yields on newly issued bonds.

Inflation: Higher inflation erodes the real value of fixed-income investments, potentially leading to lower demand for CDLB.TO and subsequently decreasing its price.

Market Sentiment: Overall investor risk appetite and sentiment towards fixed-income assets can influence demand for CDLB.TO, impacting its price positively or negatively.

Liquidity: Changes in the ETF's trading volume and liquidity can affect its price. Lower liquidity might lead to wider bid-ask spreads and potentially greater price volatility.

Fund Flows: Large inflows into CDLB.TO can push its price upwards, while significant outflows can exert downward pressure.

Economic Growth: Stronger economic growth may lead to expectations of higher interest rates, which can negatively affect CDLB.TO's price, as investors shift towards riskier assets.

Global Events: Geopolitical events and global economic conditions can influence investor sentiment and risk aversion, impacting demand for fixed-income assets like CDLB.TO.
