Economic Conditions: Broad economic factors like GDP growth, inflation, and interest rates influence investor sentiment and corporate earnings, impacting the ETF's holdings.

Sector Performance: The ETF tracks renewable energy and clean technology companies. The performance of these sectors directly affects the ETF's price.

Company Performance: The individual performance of companies within the ETF's portfolio is a key driver. Good results can increase the overall ETF value, while poor performance decreases it.

Market Sentiment: Investor attitudes towards renewable energy and clean tech influence demand for the ETF. Positive sentiment drives price up, negative sentiment drives it down.

Policy & Regulation: Government policies, subsidies, and regulations related to renewable energy affect the profitability and growth prospects of companies in the ETF.

Technology Advancements: Innovations and improvements in renewable energy technologies influence market perception and investor interest.

Currency Fluctuations: Since IWTR.US may hold international companies, currency exchange rates impact the value of those holdings when converted back to USD.

Energy Prices: The relative prices of fossil fuels versus renewable energy sources can influence investor interest and the profitability of renewable energy companies.

Competitor Performance: The performance of similar ETFs in the renewable energy sector can affect investor flows and thus the price of IWTR.US.
