Interest Rates: WTEXX's yield, and therefore its price, is heavily influenced by prevailing interest rates. When rates rise, WTEXX's yield becomes less attractive compared to newer, higher-yielding money market funds, potentially causing its price to slightly decrease.

Credit Quality: The creditworthiness of the securities held within WTEXX's portfolio (e.g., government bonds, commercial paper) impacts its price. Downgrades in the credit rating of these holdings could lead to a decrease in the fund's value.

Economic Conditions: Broader economic factors such as inflation, economic growth, and unemployment can indirectly affect WTEXX's price by influencing interest rate expectations and the overall stability of the financial markets.

Fund Management: The fund manager's investment decisions, including the selection of securities and the duration of the portfolio, can influence WTEXX's performance and thus its price, relative to other money market funds.

Supply and Demand: General market demand for safe-haven assets like money market funds can drive up the price of WTEXX, while a decrease in demand can have the opposite effect.
