Fund valuation means that the fund manager calculates the net asset value of each share of the fund by valuing securities, currencies and other assets in the fund's investment portfolio. Changes in a Fund's valuation are caused by fluctuations in asset prices and changes in holdings in the Fund's portfolio. Changes in fund valuations directly affect the trading price of fund shares, and will also affect the fund's subscription and redemption rules and the operation of the asset management plan.

Changes in fund valuations are caused by many factors, including macroeconomics, political situation, market supply and demand, etc., and show different trends at different time intervals. Fund investors should choose appropriate fund products based on their own risk preferences and asset allocation needs. At the same time, they should pay attention to changes and factors in fund valuations and adjust their investment strategies in a timely manner.

The government, industry regulatory agencies and relevant organizations should strengthen market supervision to ensure the fairness, accuracy and transparency of fund valuations. At the same time, investors should also increase their risk awareness, understand how fund products operate, avoid blindly following trends, and guard against investment risks. In this way, the fund market can develop healthily and stably and truly serve the development of social economy and the appreciation of people's wealth.
