Index Investing Explained

Index investing strategy is the trading technique of using index funds to build a portfolio. It’s a passive investment strategy that helps investors build wealth with less expense. Index funds can be mutual funds or (ETFs). They are built by financial firms to mimic a specific financial index. The fund one buys will hold the shares of stocks from companies in that particular index.

While there are financial indexes all over the world, here are a few popular that anyone can easily find index funds for:

  • S&P 500
  • Dow Jones Industrial Average
  • Nasdaq Composite
  • The Wilshire 5000
  • S&P Mid-Cap 400

Methods

Investing in index funds is incredibly easy. Moreover, an investor can choose to invest in either active or passive index investing depending on their convenience, knowledge, and time allocation.An investor can invest in index funds in two ways: through index mutual funds or ETFs.

The primary differences are:

Mutual funds – A company pools together investors’ money to purchase assets with a mutual fund. Mutual funds are bought directly from the fund and not publicly traded on the stock market. Every investor has part ownership of the fund in the share.

Mutual funds require active fund management, which means the fund’s creators are looking to beat the market. Actively managed funds have higher fees than their passive counterparts. Mutual funds offer immense diversification, liquidity and cost-effectiveness.

Exchange-traded funds– An exchange-traded fund is a bundle of assets that one can publicly trade in the stock market. ETFs are generally lower cost and more straightforward to access than mutual funds. They require passive management only and offer better liquidity than mutual funds. They are also comparatively cheaper.

A person can create both ETFs and Mutual Funds to copy a financial index. Once a person decides to invest, they can research indexes to choose the one most appealing to them.

To invest in an index fund, one can open up a brokerage account. Or, for mutual funds, one may be able to create an account directly through the company with the fund they are interested in.

Checklist

Before investing in any instrument or security, it is important to understand the applications. Below is a checklist that would help the investor choose the right ETF or mutual fund to commence their index investing strategy.

  • Account minimum – Some brokerage companies will expect an investor to have a minimum amount of money invested with them. If a person already has a brokerage account, they don’t need to worry about this.
  • Investment minimum – Some mutual funds may require to invest thousands, while some ETFs may require less than $100. The amount of money one has to invest can play a massive role in generating returns.
  • Expense ratios – The expense ratio is the amount of money that one pays to the fund managers. This fee is typically around 0.2%. Be wary of fees with high expense ratios.
  • Trading costs – Some brokerages charge a brokerage fee every time a person buys or sells an asset. If this fee is high, especially compared to the amount one is investing – one needs to find a different brokerage. It is possible to find fee-free options.
  • Retirement accounts – If someone is looking to purchase index funds for their retirement savings strategy, it is best to contact their employer’s HR department to see if such investments are available through 401k.

Examples

Let us understand the concept of passive index investing in depth with the help of a couple of examples.

Example #1

Rachel works at a successful IT company as a team head. Her schedule is naturally jam-packed. Therefore, to ensure her hard-earned salary is put to better use, she decided to invest in S&P 500 passive index investing.

In the long-run her money multiples as the economy grows. Moreover, she did not have to spend extra time on choosing the right stocks or even checking the overall balance in her portfolio. The index’s growth helped her multiply her money in exchange for a minimal fee.

Example #2

The S&P 500 is a stock market index that holds the top 500 companies in the U.S. It calculates the companies market capitalization in its index and gives a snapshot of the United States’ financial health. 

The S&P 500 is a list of companies, not a company that you directly invest in. However, one can invest in an index fund that holds all of the companies’ shares in this index. These funds are meant to match the S&P 500’s gains.

According to SPIVA, the S&P 500 has outperformed over 77% of other large-cap funds over the past five years. Since it began, the S&P 500 has returned an average of about 10% annually. 

There are multiple S&P 500 index funds. A person can choose one based on past performance, fees, and minimum investment amounts required.
