Some of the components, like 3M, have been part of the index since 1976, while others, like Amazon, were added more recently in 2024. The index weighting of each component varies, with some companies like Goldman Sachs holding a significant 8.84% weight.

The Dow Jones Index is made up of 30 companies, each representing a different industry. These companies are carefully selected to provide a snapshot of the overall market.

The oldest company on the list is Procter & Gamble, which has been a part of the Dow since 1932. This company has been around for over 190 years, making it a true American institution.

Here's a list of the companies that make up the Dow, grouped by industry:

The Dow has averaged a 5.3% return compounded annually for the 20th century, a remarkable feat that has been called "a wonderful century" by Warren Buffett.

Home Depot is a Dow component with a 6.09% weighting, which translates to roughly 2,354 Dow points based on a closing share price of over $357 on February 2. This makes it the fourth-highest weighting in the Dow Jones Industrial Average.

The company's operating model is a key factor in its success, as it tends to benefit regardless of the U.S. housing market's performance. If the economy is booming and home prices are rising, Home Depot sees gains from contractors and its enterprise-facing segments. Conversely, if mortgage rates are increasing and there's uncertainty in the housing market, Home Depot benefits from homeowners upgrading or renovating their existing homes.

The DJIA has been criticized for being an inaccurate representation of overall market performance due to its limited scope of only 30 stocks.

Ric Edelman and others argue that the DJIA is surpassed by more comprehensive indices like the S&P 500 Index or the Russell 3000 Index.

A key issue with the DJIA is its price-weighted index, which gives higher-priced stocks more influence over the average than their lower-priced counterparts.

This means that a $1 increase in a lower-priced stock can be negated by a $1 decrease in a much higher-priced stock, even though the lower-priced stock experienced a larger percentage change.

For example, during September–October 2008, AIG's stock price collapse from $22.76 to $1.35 contributed to a roughly 3,000-point drop in the index.

Goldman Sachs and UnitedHealth Group are among the highest-priced stocks in the average, giving them the greatest influence on it.

On the other hand, Cisco Systems and Coca-Cola are among the lowest-priced stocks in the average, having the least sway in the price movement.

Critics recommend the market-capitalization weighted S&P 500 Index or the Wilshire 5000, which includes most publicly listed U.S. stocks, as better indicators of the U.S. stock market.

Microsoft's success is a blend of old and new, with Azure being a dominant force in cloud infrastructure services. It's also making aggressive investments in artificial intelligence through OpenAI.

The company's legacy segments, such as Windows, are still important and generate high-margin cash flow. This cash flow fuels investments in new initiatives and earnings-accretive acquisitions.
