Supply and Demand: Market forces of supply and demand for the ETF units directly impact its price. Higher demand pushes prices up, while increased selling pressure drives them down.

NAV (Net Asset Value): The ETF's NAV, calculated based on the market value of its holdings, acts as a theoretical fair value and influences its trading price.
