Measuring Investment Performance: Understanding Market Indices

New trustees for multiemployer benefit plans can be overwhelmed by the investment knowledge that must be quickly acquired to function effectively in their new roles. This series provides in-depth information about plan investments to assist new trustees in their fiduciary duty of managing plan assets.

Understanding market indices is essential for properly evaluating your plan’s investments and investment strategy. There are a number of indices you can reference, and understanding their underlying frameworks will help you select the correct index for benchmarking investment performance.

An index is a collection of securities (tradable assets) grouped together by a common characteristic (such as size of security or location of security – i.e. , developing markets) and measured for risk and return. Some of the more common indices, with which you may be familiar, are the National Association of Securities Dealers Automated Quotations System (NASDAQ), Dow Jones Industrial Average (DOW), and Standard & Poor’s 500 (S&P 500). However, these indices are just a few of the variety of choices.

An index is often used to measure performance by benchmarking investments’ rate of return. When selecting an index against which to measure performance, it is important to find the index with a pool of underlying securities that most closely matches the underlying investments.

Before we take an in-depth look at a few of the more common indices, let’s define some helpful terms:

Large Cap/Mid Cap/Small Cap: These terms refer to the size of the companies measured in an index, and while the thresholds change over time, here are the basic guidelines:

Large Capital: Many indices measure what is termed large capital companies. This refers to companies that have a market capitalization value (the total value of the issued shares of a company) of over $10 billion. You’ll often see the shortened term “large cap.”

Middle Capital: These are companies with market capitalization between $2 and $10 billion. More commonly referred to as “mid cap.”

Small Capital: While the definition may vary among brokerages, this generally refers to a company with a market capitalization between $300 million and $2 billion. As with the other two terms, it is most often shortened to “small cap.”

Some indices only measure companies of a certain size. For example, the Russell 1000 only measures large cap companies.

Price-to-Book Ratio: This ratio, also known as the price-equity ratio, compares a stock’s market value to its book value. This is often used to gauge a stock’s relative value. A company trading at a low book price is often thought to be undervalued, but the low price could be an indicator of an issue with the company.

Weighting: Most indices are market-cap weight, so the stocks with the largest value have a larger influence on the index. Some, such as the Dow Jones, are price weighted, where each stock influences the index in proportion to its price per share.

Here is an overview of a few of the more common indices you can use when benchmarking your investments’ performance:
