What Exactly Is the Dow Jones US Completion Total Stock Market Index?
In simple terms, the Dow Jones US Completion Total Stock Market Index is designed to measure the performance of the entire US stock market. It aims to be as comprehensive as possible, including virtually all investable US equities, from the mega-cap companies like Apple and Microsoft to small-cap firms and everything in between.
The name itself provides key clues:
- Dow Jones: It is part of the extensive family of indices calculated and maintained by S&P Dow Jones Indices, one of the world's leading providers of financial market indices. The index is designed to "complete" the picture provided by large-cap indices like the S&P 500. * Completion: This is the most important word. Consider this: * US: It is limited to companies incorporated in the United States and listed on US exchanges. If the S&P 500 is the body of a giant, the Completion Index represents the arms, legs, and everything else that makes up the whole person.
- Total Stock Market: It seeks to represent the "total" market, meaning it has a very broad base and high diversification.
Essentially, if you wanted a single investment that mirrored the entire US stock market's movement, this index is the closest proxy available.
How Is the Index Constructed? The Selection Criteria
The methodology behind the Dow Jones US Completion Total Stock Market Index is systematic and rules-based, ensuring objectivity and transparency. Its construction can be broken down into several key steps:
- Universe Selection: The starting point is the entire universe of US-listed stocks. This includes companies on the New York Stock Exchange (NYSE) and the Nasdaq.
- Inclusion Criteria: To be included, a stock must meet specific liquidity and market capitalization requirements. This ensures the index only includes stocks that are reasonably easy to buy and sell without significantly impacting the price. Unlike the S&P 500, which has a strict earnings requirement, the Completion Index is more focused on market size and liquidity.
- Market Capitalization Coverage: The index is designed to include approximately 99.5% of the US equity market's total market capitalization. This is its defining feature. It doesn't just sample the market; it tries to capture almost all of it.
- Weighting Method: The index uses a market-capitalization weighting methodology. So in practice, larger companies have a greater influence on the index's performance than smaller ones. Take this: a 1% move in Apple's stock will have a much larger impact on the index than a 1% move in a small-cap biotech company. This reflects how a typical investor's portfolio would be weighted if they owned the entire market.
Why Does This Index Matter? The Investor's Perspective
For individual investors and financial professionals, the Dow Jones US Completion Total Stock Market Index is an indispensable tool for several reasons:
- The Ultimate Benchmark for Broad Exposure: Many investment funds, particularly index funds and ETFs (Exchange-Traded Funds), use this index as their benchmark. If you invest in a fund that aims to "beat the market," the manager's performance is often measured against the return of the Dow Jones US Completion Total Stock Market Index. Beating this index is considered a significant achievement because it's so difficult to outperform a measure of nearly everything.
- A Foundation for Asset Allocation: For investors building a diversified portfolio, this index represents the "US stocks" allocation in its purest form. It provides a baseline to understand how much of a portfolio should be dedicated to US equities based on their long-term goals and risk tolerance.
- Analyzing Market Health: Because it covers the entire market, movements in this index can be a more reliable indicator of overall economic health than a narrow index. A rising index suggests broad-based corporate growth, while a declining one can signal widespread economic concerns, even if the mega-cap stocks are holding up.
- Accessing Small and Mid-Cap Growth: While large-cap stocks get most of the attention, historical data shows that small and mid-cap companies have often provided higher long-term returns than their larger counterparts (though with higher volatility). By tracking the Completion Index, investors can see the contribution of these often-overlooked segments of the market.

Potential Drawbacks to Keep in Mind
- Inherent Volatility from Small‑Cap Inclusion – While the index smooths away single‑stock risk, the smaller‑cap constituents can introduce more price swings than a large‑cap‑only benchmark.
- Higher Turnover – Because the index is rebalanced as market caps shift, funds tracking it may experience more frequent buying and selling, which can generate modest tax implications in taxable accounts.
- Diluted Alpha Opportunities – The broad nature of the index makes it harder for active managers to outperform significantly without taking on additional risk.
Practical Ways to Use the Completion Index in Your Strategy
- Core‑Satellite Approach – Allocate a large portion of your equity exposure (e.g., 60‑80 %) to a total‑market ETF that tracks the Completion Index. Then layer in “satellite” positions—such as sector ETFs, international funds, or thematic strategies—to add specific tilts or active bets.
- Retirement Accounts – For 401(k) or IRA accounts, choose a target‑date fund whose glide‑path relies on a total‑market index fund. This gives you instant diversification without having to build the portfolio yourself.
- Tax‑Efficient Wrapping – In a taxable brokerage, consider holding the Completion Index ETF inside an IRA or 401(k) to shelter the higher turnover from annual capital‑gain distributions.
