Fund Performance: A strong track record of consistent returns, especially when exceeding benchmarks, attracts investors and increases demand, thus pushing the price up.

Interest Rate Changes: Money market funds invest in short-term debt securities. Rising interest rates generally increase the yield on these securities, making the fund more attractive and potentially increasing its price.

Credit Quality of Holdings: The creditworthiness of the underlying debt instruments significantly impacts the fund's perceived safety. Higher quality holdings tend to support a higher price.

Overall Market Conditions: General economic sentiment and market stability can influence investor confidence in money market funds. Turbulence may drive investors to seek the relative safety of these funds, increasing demand.

Fund Size & Liquidity: A larger, more liquid fund can attract more investors as it suggests easier entry and exit.
