QQQT-B.TO is a Canadian-listed ETF designed to track the NASDAQ 100 index. **Underlying Index Performance:** The primary driver is the performance of the NASDAQ 100. Upward movements in the index generally translate to higher prices for the ETF and vice versa. **Currency Fluctuations:** As the underlying assets are primarily US-based stocks, fluctuations in the CAD/USD exchange rate will impact the ETF's price. A stronger Canadian dollar reduces the value of the US-based holdings when converted back to CAD. **Supply and Demand:** Market forces influence the ETF's price. Higher demand can lead to price increases, while increased selling pressure can cause a price decrease. **Management Fees and Expenses:** While generally small, the ETF's management expense ratio (MER) and other operating expenses slightly reduce the overall return and affect the price over time. **Investor Sentiment:** General market sentiment towards technology stocks and growth stocks can affect investor demand for QQQT-B.TO, influencing its price.
