Close-end funds generally issue shares to the
public just once, when they are created via an initial public
offering. These shares are then listed for trading on a stock
exchange. Investors, who dont wish any longer to invest in the
funds, cannot sell their shares back to the funds. Instead, they
must sell their shares to another investor in the market as the
price they may receive may be hugely different from its net
asset value. It may be at a premium to net asset value (higher
than the net asset value) or more commonly at a lesser to net
asset value (lower than the net asset value). A professional
investment manager will oversee the portfolio, in buying or
selling securities whichever is appropriate.
