Sector Concentration Risk: The ETF is concentrated in the transportation sector, making it susceptible to adverse economic or regulatory developments that specifically impact transportation companies, rather than being diversified across many sectors.

Economic Sensitivity Risk: Transportation companies are highly cyclical and sensitive to the overall health of the economy, as demand for freight and passenger travel often fluctuates with economic growth or contraction.

Fuel Price Volatility Risk: A significant operating expense for many transportation companies (airlines, trucking, railroads) is fuel. Volatile or rising fuel prices can directly impact their profitability and operating margins.
