Underlying Asset Performance: The primary driver is the performance of the Brazilian small-cap companies included in the index tracked by the ETF. Positive performance leads to higher ETF prices, and negative performance causes prices to fall.

Supply and Demand: Market dynamics, including buying and selling pressure, influence the ETF's price. High demand generally increases the price, while high selling pressure lowers it.

Investor Sentiment: Overall market sentiment towards Brazilian small-cap stocks affects demand. Positive sentiment attracts investors, driving up the price, and negative sentiment leads to selling pressure.

Exchange Rate Fluctuations: Since the underlying assets are Brazilian companies traded in BRL, exchange rate fluctuations between the BRL and other currencies can impact the ETF's price, especially for foreign investors.

Management Fees and Expenses: The ETF's expense ratio and other operational costs can slightly affect its price over time. Higher expenses can lead to lower returns and potentially a lower price compared to similar ETFs.

Dividend Distributions: Dividend payouts from the underlying stocks can influence the ETF's price. The ETF's price may slightly decrease when dividends are distributed, as the ETF's asset value is reduced.

Economic Conditions: Broader economic factors in Brazil, such as GDP growth, inflation, interest rates, and political stability, can affect the performance of Brazilian small-cap companies and, consequently, the ETF's price.
