Underlying Index Performance: VTEI.US tracks the FTSE Global Infrastructure Index ex US. Therefore, the price is primarily dictated by the performance of the companies within that index, which are global infrastructure companies excluding those domiciled in the United States.

Currency Fluctuations: Since the index includes international stocks, fluctuations in currency exchange rates can impact the ETF's price. A stronger US dollar may decrease the value of holdings in other currencies when converted back to USD, and vice versa.

Interest Rate Changes: Infrastructure companies are often sensitive to interest rate changes due to their capital-intensive nature. Rising rates can increase borrowing costs and potentially decrease profitability, affecting stock prices and thus the ETF's price.

Economic Growth: General economic conditions in the countries where the underlying infrastructure companies operate can influence their profitability and, consequently, the ETF's price. Stronger economic growth typically benefits infrastructure demand.

Inflation: Infrastructure assets can sometimes act as a hedge against inflation. Higher inflation can lead to increased prices for infrastructure services and potentially higher revenue for the companies held by the ETF, positively impacting its price.

Supply and Demand: As with any ETF, the market forces of supply and demand can cause the market price of VTEI.US to deviate slightly from its net asset value (NAV). High demand can push the price above NAV, and high supply can pull it below.
