Net Asset Value (NAV) – It represents the value of one share of the fund just like the price quote for a stock. NAV is calculated by taking the total value of the fund’s investments, subtracting its expenses, and dividing by the number of shares in the fund. Unlike a stock quote, NAV is calculated once a day after the market closes at 4 PM ET.
