Investment Fund

What is an Investment Fund?

An investment fund is a pool of capital belonging to numerous investors that is used to invest in securities like stocks, bonds, and other assets. Each investor in the fund retains ownership and control over a certain number of shares in proportion to the amount they invested.


Investment funds allow investors to hand over control over tasks such as portfolio allocation and liquidity management to a professional in exchange for a fee.

How Do Investment Funds Work?

Investment funds raise money from many investors and use it to build a portfolio of financial instruments aligned with the fund’s strategy and objectives. These investments are selected and managed by seasoned professionals.

When you invest in a fund, you buy shares or units that represent ownership in the fund’s holdings. The value of the shares will fluctuate based on the performance of the investments that make up the fund’s portfolio.

As an investor, you do not have direct control over which assets the fund buys or sells.

The fund manager oversees the portfolio, conducting analysis and research to decide which investments to include and in what quantities. They determine when to buy or sell based on the fund’s goals. The manager’s investment decisions aim to produce returns for investors while adhering to the fund’s risk parameters.

In exchange for this professional management, funds charge fees and expenses that are deducted from its total assets. These include management fees paid to the advisor as well as operational and transaction costs.

The fees reduce the fund´s net returns but provide convenient access to skilled investment management.

Types of Investment Funds

5 Types of Investment Funds

Below are the five most common types of investment funds:

  1. Mutual Funds: They allow investors to pool money in a fund that purchases a diverse portfolio of stocks, bonds, and other securities. They offer built-in diversification and professional management. Mutual funds sell and redeem shares directly with investors daily based on their net asset value (NAV).
  2. Exchange-Traded Funds (ETFs): ETFs are investment funds that trade intraday on stock exchanges like individual securities. ETFs track underlying indexes but trade at market prices which may deviate from their net asset value (NAV) at times. They offer diversified exposure to markets and often have lower costs than mutual funds.
  3. Hedge Funds: Hedge funds are privately organized investment funds open only to accredited high-net-worth investors. They implement flexible investment strategies aimed at generating outsized returns through techniques like short selling, leverage, and derivatives trading. Hedge funds charge much higher fees and are less regulated than traditional funds.
  4. Private Equity Funds (PE): These funds raise money from investors to acquire publicly traded companies to optimize their operations and, ultimately, raise their market value. Once the company has been restructured and its value has expanded, it exits the investment at a profit.
  5. Venture Capital Funds: VC funds pour money into early-stage businesses – a.k.a. startups – that have created promising products, services, and business models. They take significant risks but tend to invest small amounts into a large number of different ventures to diversify their portfolios. Many of these investments will fail, but a handful will deliver outstanding returns that should make up for those that did not perform as expected.

In addition, there are industry-specific funds like real estate funds, commodity funds, and emerging market funds.

Funds can also be actively managed if the manager makes tactical bets or passively managed if they are designed to perform in the same way as a certain benchmark like the S&P 500 or Nasdaq 100 index.

Benefits of Investment Funds

Investment funds provide several advantages for investors, including these:

Advantages Description
Diversification Funds invest in a basket of securities to reduce risk and volatility versus owning just a few assets.
Professional Management Fund managers have the expertise to research and select investments as well as actively manage the portfolio in response to changes in market conditions.
Cost Efficiency Aggregating assets into a fund allows cost savings through economies of scale in trading, research, and management.
Convenience A pool of capital gives funds more advantageous access to the markets and various asset classes that may otherwise be inaccessible for individuals unless they have a high net worth.
Liquidity Open-end mutual funds process purchases and redemptions daily so investors can enter and exit holdings with ease. Meanwhile, the shares of ETFs can be easily sold as if they were regular stock.
Transparency Funds publicly disclose key details about their operations, including a full list of their holdings, historical returns, fees, and investment strategy.
Regulation Securities regulators oversee funds to protect investors through requirements like regular reporting and independent audits.


Risks and Drawbacks of Fund Investing

Investment funds also come with some potential downsides:

Downsides Description
Market Risk Funds with exposure to stocks and certain high-risk securities are still vulnerable to market volatility and may generate sizable losses.
Manager Underperformance An actively managed fund may fail to beat its benchmark index after fees are deducted.
High Costs Fund-specific expenses like management fees can reduce total returns compared to passive index investing.
Lack of Control Investors cannot influence the decision of the fund’s manager in any way.
Less Liquidity Some funds, like hedge funds and private equity funds, may impose lock-up periods or redemption restrictions.
Tax Inefficiency Investors may incur capital gains taxes as the fund buys and sells the holdings that make up the portfolio. A high portfolio turnover rate may hurt the fund’s return.
