Underlying Index Performance: The ETF’s price closely tracks the performance of the Ibovespa Index. Upward index movement typically raises the ETF's price, and vice versa.

Supply and Demand: Market demand for the ETF influences its price. Higher demand can push the price above the net asset value, while increased selling pressure can lower it.

Expense Ratio: Although not directly impacting daily price fluctuations, a higher expense ratio can erode returns over time, making it comparatively less attractive to investors.

Market Sentiment: Overall investor confidence and market conditions affect demand for Brazilian assets. Positive sentiment can increase investment, raising ETF price.

Currency Fluctuations: Changes in the Brazilian Real (BRL) against other currencies impact the ETF's value, especially for international investors. Real appreciation raises price.

Dividend Payments: Dividends paid out by the underlying stocks influence the ETF's total return, and can affect short-term investor interest around dividend distribution dates.
