What is the difference between NAV and market value in investment analysis?

The Net Asset Value (NAV) represents the value of a mutual fund's assets minus its liabilities, calculated at the end of each trading day. Market value, on the other hand, is the current price at which an asset can be bought or sold in the market. In investment analysis, NAV is used to assess the fund's performance, while market value reflects the real-time value of the investment.
