What Is a Mutual Fund?

A mutual fund is a fund that pools money from different investors to invest the money in securities such as bonds, stocks, and short-term debts.

When you invest in a mutual fund, the fund invests your money into stocks and other similar investments.

The return on your investment will come from the profit the fund realizes from investing in these securities.

Investing in a mutual fund offers some key benefits, which include:

  • Diversification
  • Low-Cost
  • Liquidity

Mutual funds reserve some outstanding features that make investors buy into them:

  • Diversification

A perfect adage to stress this point is, “Don’t put all your eggs in one basket.”  The span of a mutual fund's investment is usually comprehensive.

They invest in a large number of companies and industries across sectors.

This is a smart way to mitigate the risk involved in investment.

If one company fails, another company can cover those losses.

  • Low-Cost Investments

A good investment aims to “spend less to make more.”

Every investor should seek the lowest-cost fund that meets their investment needs.

  • Liquidity

One of the many benefits you reap when you invest in a mutual fund is liquidity.

The liquidity of an investment means the ability to convert it to tangible money easily.

Mutual funds allow investors to redeem their shares quickly and at any time.
