Exchange rates: The exchange rate between the Brazilian Real and other currencies, particularly the US dollar, influences the price, as the ETF's underlying assets might be denominated in other currencies.

Benchmark index performance: The performance of the index IFRA11.SA tracks directly impacts its price. Positive index returns generally lead to price increases and vice versa.

Fund management fees: The expenses associated with managing the ETF directly affect its returns. Higher fees reduce the overall profitability, potentially impacting its price negatively.

Supply and demand: Like any asset, the forces of supply and demand affect the ETF's market price. High demand and limited supply can cause price increases.
