Underlying Index Performance: FLXK.F tracks a specific index, so the price movements of its underlying assets directly impact the ETF's value. If the index goes up, the ETF price tends to rise, and vice versa. Supply and Demand: Basic economic principles apply. Higher demand pushes the price up, while increased selling pressure can lower it. Net Asset Value (NAV): The NAV represents the total value of the ETF's holdings minus liabilities, divided by the number of outstanding shares. Deviations between the ETF's price and its NAV can create arbitrage opportunities. Expense Ratio: The ETF's expense ratio, which covers operating costs, indirectly impacts its price. Higher fees can slightly reduce returns over time, compared to a lower-cost ETF tracking the same index.
