The CRSP US Total Market Index is a market-capitalisation-weighted index that represents the performance of the US stock market, including both US domestic and international companies listed on major US stock exchanges. The Center for Research in Security Prices (CRSP) at the University of Chicago maintains the index. It is considered to be one of the most comprehensive benchmarks for the US equity market and is considered to represent the overall health of the US stock market. The index is often used as a benchmark by investors to measure their performance.
The index includes large-cap, mid-cap, small-cap, and micro-cap stocks. The index is also adjusted for changes in the market capitalisation of its constituents, ensuring that it remains representative of the market as a whole.
As of 2023, the CRSP US Total Market Index included approximately 4,000 stocks. However, the number of stocks in the index can change over time as companies enter or exit the market or are added or removed from the index for other reasons. The CRSP at the University of Chicago, which maintains the index, regularly updates its composition and methodology to ensure it remains representative of the US equity market.
Significance of CRSP US Total Market Index
The CRSP US Total Market Index is important to investors for several reasons. Firstly, investors widely use it as a benchmark to measure their performance. This is because the index represents the performance of the entire US equity market, which is a key factor in assessing the performance of any investment portfolio.
Secondly, the CRSP US Total Market Index is a valuable tool for analysing trends in the US equity market. By examining the index’s performance over time, investors can identify long-term trends and cyclical patterns in the market.
Finally, the CRSP US Total Market Index is a valuable indicator of the overall health of the US economy. As the US equity market is closely tied to the performance of the broader economy, changes in the index can be an early indicator of economic trends.
Calculation used in CRSP US Total Market Index
The CRSP US Total Market Index is calculated using a market-capitalisation-weighted methodology. This means that the index is weighted based on the total market capitalisation of each of its constituent stocks. The market capitalisation of a stock is calculated by multiplying its current share price by the total number of shares outstanding.
The formula for calculating the CRSP US Total Market Index is as follows:
Total Market Index = (Total Market Capitalization of All Stocks in Index) / (Base Market Capitalization)
The base market capitalisation is a fixed number that is set at a specific date in the past. It ensures that the index remains representative of the overall market, even as the market capitalisation of its constituent stocks changes over time.
Criteria of a company to enter CRSP US Total Market Index
- Be a US company listed on the NYSE, NASDAQ, or AMEX exchanges, or have an ADR listed on these exchanges.

- Meet minimum liquidity requirements, including trading volume and the number of shareholders.
- Have positive earnings in the most recent fiscal year or over the past four quarters.
- Meet certain other eligibility criteria related to corporate governance and financial reporting.
After a company meets these eligibility criteria, it can be added to the CRSP US Total Market Index per the index’s rules and methodology. The index is rebalanced periodically to ensure its composition represents the US equity market.

Pros and cons of the CRSP US Total Market Index
Some of the potential pros and cons of investing in the S&P 500 index include the following:
- Comprehensive coverage: The CRSP US Total Market Index covers nearly 100% of the US equity market. This provides investors with a comprehensive view of the US stock market and can help to reduce concentration risk.
- Diversification: The index includes a broad range of companies across various sectors and industries, which helps to spread out investment risk. This can be particularly beneficial for investors looking to build a diversified portfolio.
- Transparency: The methodology used to construct the index is transparent, which makes it easier for investors to understand how the index is constructed and how it is likely to perform under different market conditions.
- Low costs: The CRSP US Total Market Index is typically used as the underlying benchmark for low-cost index funds and exchange-traded funds (ETFs), which can help investors to keep their investment costs low.
- Market-capitalisation weighting: The index is weighted by market capitalisation, which means that larger companies significantly impact the index’s performance. This can lead to a concentration of risk in the largest companies, which may not be suitable for all investors.
- Very limited international exposure: The index only includes companies listed on major US stock exchanges, which means that it provides minimal exposure to non-US markets and economies.
Advantages and disadvantages of CRSP US Total Market Index compared to the S&P 500
- More comprehensive: The CRSP US Total Market Index is designed to track the performance of the entire US stock market, while the S&P 500 only includes the largest 500 companies. This means that the CRSP index may provide a more comprehensive picture of the overall market, including mid-cap and small-cap companies not included in the S&P 500.
- Diversification: Because the CRSP US Total Market Index includes a wider range of companies, it may provide greater diversification benefits for investors than the S&P 500.
- Low expense ratios: Many CRSP US Total Market Index funds and ETFs have lower expense ratios than S&P 500 funds and ETFs.
- Higher volatility: Because the CRSP US Total Market Index includes mid-cap and small-cap companies, it may be more volatile than the S&P 500, composed primarily of large-cap stocks.
- Less visibility: The S&P 500 is widely recognised and closely followed by investors, analysts, and the media. This can make it easier to gain insights towards making investment decisions. The CRSP US Total Market Index is less well-known and receives lesser attention from investors and analysts.
History of CRSP US Total Market Index
The CRSP US Total Market Index has a rich history dating back to the 1960s when the University of Chicago’s Center for Research in Security Prices (CRSP) began compiling data on the US stock market.
In 1964, CRSP launched the CRSP Stock Database, which contained historical data on all US stocks listed on the NYSE, AMEX, and NASDAQ exchanges. This database became the foundation for the CRSP US Total Market Index, launched in 1992 as a comprehensive measure of the US equity market. Over the years, the index has become one of the most widely used benchmarks for the US equity market.
