Open-End Fund

Fund structure that issues and redeems shares on demand, usually at net asset value rather than through exchange trading.

On this page

An open-end fund is a fund structure that issues and redeems shares on demand, usually at net asset value rather than through ordinary exchange trading.

It matters because this structure explains how many mutual funds work in practice: investors transact with the fund itself, and pricing is typically tied to end-of-day NAV rather than intraday market supply and demand.

How It Works

An open-end fund generally:

  • creates new shares when investors buy in
  • redeems shares when investors cash out
  • prices transactions based on net asset value
  • keeps capital flows inside the fund vehicle rather than relying on secondary-market share trading

Why It Matters

The structure affects liquidity, pricing, taxation, and investor behavior. It also helps explain why traditional mutual funds feel different from ETFs and closed-end funds.

  • Mutual Fund: A common example of an open-end fund structure.
  • Net Asset Value: Standard pricing basis for many open-end fund transactions.
  • Closed-End Fund: Contrasting structure with fixed shares traded in the market.
