When constructing an investment portfolio, you'll probably include a variety of stocks and bonds among the securities you purchase. Because ETFs are traded on the exchange, there is always an ask price (buyers get this price) and a bid price (sellers get this price).
One fund could include tens, hundreds, or even thousands of individual stocks or bonds in a single fund. Exchange-traded funds (ETFs), index mutual funds and actively managed mutual funds can provide broad, diversified exposure to an asset class or region or a specific market niche, without having to buy scores of individual securities.
The fund will only buy the stocks that make up the index the fund will be tracking in the proportion they are represented in the index. A bond index or stock index is tracked by most ETFs. Mutual funds, however, can only be purchased or sold at the end of the trading day after the market closes and their price is based on Net Asset Value (NAV) - the value of fund assets minus liabilities divided by the number of shares.

Unlike mutual funds, however, ETF shares are traded on a national stock exchange and at market prices that may or may not be the same as the net asset value (NAV”) of the shares, that is, the value of the ETF's assets minus its liabilities divided by the number of shares outstanding.
A fund's investment strategy, as stated in its prospectus, determines the mix of securities the fund manager chooses to purchase and hold. Emerging market stocks or high-yield bonds are less efficient markets where deep research and a proven strategy can likely pay off.
You can invest broadly (for example, a total market fund ) or narrowly (for example, a high-dividend stock fund or a sector fund )—or anywhere in between. The price of the fund is not determined until end of business day , when net asset value (NAV) is determined.
