Closed-end funds (CEFs), around since 1893, function much like pooled mutual funds but differ in that they have a fixed number of shares trading on public exchanges after their IPO. 

Unlike mutual funds, which create or redeem shares daily to match investor flows, CEFs trade like stocks, meaning their prices can swing above or below the fund’s actual net asset value (NAV). This market pricing dynamic allows investors to potentially buy a dollar’s worth of assets for 90 cents, creating attractive opportunities to purchase CEFs at discounts. 

In addition, CEFs can use leverage to amplify returns, which often translates to higher distribution yields than traditional funds. However, investors should generally avoid paying a premium above NAV, just as they wouldn’t pay $1.10 for a dollar. 

Finsum: CEFs trading at reasonable discounts with strong yields may offer a compelling addition to income-seeking portfolios, combining discounted asset value with robust payouts.
