We’ve received a few questions over the last several weeks on the differences between major US indices. The answer to, “how’s the market doing?”, can sometimes depend on the index used. According to the Index Industry Association, there are over 3.3 million indices compiled by 14 different companies. The Financial Times found that on a worldwide basis there are over 70 times more stock indices than there are individual stocks. In our client question of the month we will examine the differences between the three most widely referenced US indices, the S&P 500, the Dow Jones Industrial Average (Dow), and the Russell 3000.

Let’s get into the details on the history, structure, methodology, and differences between each index.

History and Structure
S&P 500: The origin of the S&P 500 goes back to 1923, when Standard & Poor’s introduced a series of indices that included 233 companies and covered 26 industries. The S&P 500 in its current form was introduced in 1957. The S&P 500 is the only stock market benchmark serving as an economic indicator in The Conference Board Leading Economic Index.

The S&P 500 is widely regarded as the best single gauge of large-cap US equities. Over $6.5 trillion in active funds and $3.4 trillion in passive funds utilize the S&P 500 as a benchmark. The index covers approximately 80% of the investable US equity market. Source: S&P Dow Jones Indices.

The Dow: Charles Dow founded the Dow Jones Industrial Average on May 26, 1896. The Dow was initially comprised of 12 stocks (versus 30 today), including a leather maker, a steel provider, and a sugar producer. According to S&P Dow Jones Indices, the Dow rose to prominence during the stock market crash of 1929 when investors began monitoring the index as a representation for the overall market.

The Dow is a price-weighted index of 30 US blue-chip companies. The index covers approximately 25% of the investable US equity market. The index provides suitable sector representation except for the transportation industry and utilities sector. Source: S&P Dow Jones Indices.

Russell 3000: The Russell US indices were created in 1984 by the Frank Russell Company with the goal of providing accurate representation of the investable US equity market. The Russell indices are designed to provide performance benchmarks for active strategies, as the underlying basis for passive investment products, and as a proxy for US equities in asset allocation decisions.

The Russell 3000 is designed to gauge the entire US stock market. Over $6 trillion in active funds and $1 trillion in passive funds utilize a Russell index as a benchmark. The Russell 3000 index covers approximately 98% of the investable US equity market. Covering the entire US market would require purchasing several thousand small or potentially illiquid companies. Source: FTSE Russell.

How are index weights calculated?
Dow Jones Industrial Average: Price Weighted
In a price-weighted index, the weight of each security is determined by its share price. A stock with a higher share price will have a greater weight and more impact on the index performance than a lower price one. To start, a price weighted index assumes that each security is held in the same quantity. Next, an adjustable divisor accounts for actions that impact the shares outstanding, including, price adjustments, special dividends, stock splits, rights offerings, additions, and/or deletions.

S&P 500 and Russell 3000: Float Adjusted Market Cap Weighted
In a float adjusted market cap index, the weight of each security is determined by its market capitalization (= share price X public shares outstanding). Larger market cap stocks will have a greater weight and more impact on the index performance than smaller ones. Float-adjusted means that the total shares outstanding for each security only includes those that are held by the public and are available for trading. Restricted shares or strategic holdings are not included.

What are the differences between each index?
The difference between each index is probably best illustrated with the following chart. Note that the S&P 500 and Russell 3000 are similar while the Dow Jones Industrial Average is unique. We believe it is important to understand the differences across methodology, holdings, market caps, sectors, and returns when answering the “how’s the market doing?” question or using an index as a benchmark. We will usually reference the S&P as a proxy for the US market since it is the most well-known index, but we prefer the Russell 3000 as a benchmark since it covers most of the investable market by including mid and small cap stocks. At Winthrop Wealth Management, our US equity portfolios most closely resemble the Russell 3000 due to the potential return and diversification benefits of investing in mid and small cap stocks.

As a quick side note, we notice that references to the Dow mostly occur during periods of market volatility. The price of the Dow is much larger than either the S&P 500 or Russell 3000. As of month end, the price of the Dow was at 26,917, the S&P 500 at 2,977, and the Russell 3000 at 1,743. Note that the price of the index is used to calculate performance and does not reflect the value or total market capitalization of the underlying holdings. While the Dow has the highest price of the three indices, it covers the least amount of the investable US market. We will use the following market drop in August as an example:

Anecdotally, we received several more questions referencing the decline in the Dow even though each index was down about -3%. Why? Moves in the Dow just sound more dramatic. The Wall Street Journal headline of “Dow Sheds 800 in Biggest Drop of Year” sounds more severe than “S&P Drops 86” or “Russell 3000 Declines 50”. Keep in mind that financial newspapers or televisions stations get paid for readers and viewers, not necessarily for providing sound investment advice. While we monitor the Dow as one of several indices, we notice that others usually bring it up only in reference to large price swings.
