Mutual Funds ## What Is a Mutual Fund? A mutual fund pools money from many investors to purchase a diversified portfolio of securities — stocks, bonds, or a mix — managed by a professional portfolio manager.

They continuously issue new shares when investors buy in and redeem (cancel) shares when investors sell. There is no fixed share count — the fund expands and contracts with investor demand. Net Asset Value (NAV) is the per-share price at which you buy or redeem shares: > NAV = (Total Assets − Total Liabilities) ÷ Shares OutstandingExample: A fund holds $50 million in securities, has $500,000 in liabilities, and 5,000,000 shares outstanding. > NAV = ($50,000,000 − $500,000) ÷ 5,000,000 = $49,500,000 ÷ 5,000,000 = $9.90 per share NAV is calculated once per day after the market closes at 4:00 PM ET. All buy and sell orders placed during the day execute at that end-of-day NAV — known as forward pricing. There is no intraday trading. --- ## Closed-End Funds Closed-end funds issue a fixed number of shares through an IPO and then trade on a stock exchange (NYSE, NASDAQ) just like any equity security.
