One of the most important concepts new investors in the stock market need to learn has to do with sectors and industries.  I want to take a few moments to walk you through the definition of these concepts, explain what they are in practical terms, and show you how they fit into one of America's largest stock market indices, the S&P 500.  Though it will only take a brief amount of your time, you'll be glad you learned the difference once and for all.

What Is the Difference Between a Sector and an Industry?

The general economy and stock market are organized into two tiers. The highest tier, a sector, is a broad grouping of companies that have similar economic characteristics. There are currently 10 major sectors that most investors use when breaking down the corporations and other issuers of securities such as stocks and bonds.

Sectors, in turn, are broken down into sub-categories known as industries. This allows a closer grouping of similar businesses. For example, both Walmart, the discount retail chain, and Tiffany & Company, the luxury jeweler, are included in the consumer discretionary sector. However, they are sorted into different industries.

What Are the Advantages of Paying Attention to Sectors and Industries?

Examining sectors and industries allows you compare one business to its closest competitors. You may think a certain stock is a good purchase, but until you research its rivals, you won't know for sure. 

Looking at sectors and industries also helps you become familiar how businesses interact with another. For example, if you believe that energy prices are going to decline, you might find transportation stocks appealing, because you believe one of the biggest cost inputs—gasoline and jet fuel—is about to plummet. When combined with disciplined, long-term, tax-efficient, low-turnover, highly passive investing, this knowledge can be a ticket to building wealth.

It's also now possible to invest in an entire sector or industry with one purchase. Rather than buy shares of every company in a given industry or sector, you can get exposure to all of them in a single investment. With exchange traded funds (ETFs) smaller investors can often buy a diversified basket of an entire grouping, often with little to no commission and expense ratios that are typically less than 0.50% to 1.00%. These ETFs are similar to mutual funds but trade like stocks, and allow an investor to get exposure to a wide range of investments in a sector or industry without needing to research individual stocks.


Many financial advisors recommend that investors try to maintain a portfolio that offers good exposure to all of these industries and sectors. 

For now, let's dive into the sector and industry breakdown of the United States stock market as a whole. I'm going to use the S&P 500 index as a proxy for the stock market. As of the most recent stock market close on February 26th, 2016, the total value of all stocks in the S&P 500 index came to $17.87 trillion.
