Part 4/8:
Investors should be aware that index funds are priced only once a day after the market closes, based on the total value of the fund's assets minus expenses. This means that if an order is placed during market hours, it will not be executed until the net asset value is determined at the end of the day. Despite this lack of real-time trading, index funds are highly favored for their low costs, low effort, and solid long-term performance.
