Underlying Index Performance: The primary driver is the performance of the S&P/BMV IPC index, which VMEX19.MX tracks. Upward or downward movements in the index directly influence the ETF's price.

Supply and Demand: General market sentiment and investor demand for Mexican equities influence the ETF's price. High demand can push the price up, while increased selling pressure can lower it.

Foreign Exchange Rates: Fluctuations in the MXN/USD exchange rate affect the ETF's value for international investors. A stronger MXN can increase the value for USD-based investors, and vice-versa.

Management Fees and Expenses: The ETF's expense ratio reduces returns. Higher expenses can slightly dampen the ETF's overall performance and price appreciation.

Dividend Payments: Dividends paid by companies within the S&P/BMV IPC index are reflected in the ETF's price. Dividend distributions may cause a slight price decrease on the ex-dividend date.

Economic Conditions in Mexico: Factors like GDP growth, inflation, interest rates, and political stability in Mexico influence investor confidence and, consequently, the performance of Mexican stocks and the ETF.

Global Market Conditions: Global economic events, trade policies, and international investor sentiment can impact emerging markets like Mexico, affecting the ETF's price.

Tracking Error: The ETF aims to mirror the S&P/BMV IPC index, but slight deviations (tracking error) can occur due to factors like fund expenses, cash drag, and sampling techniques, impacting the ETF's performance relative to the index.

Arbitrage: Market makers can arbitrage price discrepancies between the ETF and its underlying assets, which keeps the ETF price aligned with the net asset value of the holdings.
