The first famous index: When was the Dow Jones created?Įquity indexes are hypothetical portfolios of stocks built to tell a story of how shares moved throughout a trading day. The Dow is a great place to start that education. So, as you grow as an investor, it’s worthwhile to understand how any index you follow is built. More on that below with one key point: Weighting is central to the way indexes are built and the value they have.
Weighting determines the influence of shares in any portfolio by using factors like price and market capitalization. All stock indexes-any investment index, really-has one consistent mathematical process known as weighting. A stock index is a hypothetical portfolio of shares organized by various industries, company sizes, or other factors. Indexes are a way to measure the performance of a group of assets in a particular way.
Today, many investors believe this group of major indexes-and thousands of subindexes that measure categories of investments large and small across the investment world-can provide a better view of what’s happening across particular industries, businesses of a certain size, and the economy as a whole. Today’s primary market indexes are the Dow, S&P 500® index (SPX), Nasdaq Composite® ($COMP), and Russell 2000® (RUT). With all respect to inventor Charles Dow-founder of Dow Jones & Co and The Wall Street Journal-there’s a reason the $DJI has become a big fish in a bigger pond of major indexes that offer the biggest picture on the markets.Ī stock market index measures the performance of a collection of stocks. A global institution for nearly 130 years, the Dow is still considered a top barometer of what’s going on in the broader economy.īut it’s clearly not the only one anymore. Even today, the one we probably notice the most involves the closing number of the Dow Jones Industrial Average ® ($DJI). So much of what most people initially understand about investing comes from the business headlines we see and hear every day. Why indexes rebalance and what to watch for Learn how the Dow is weighted differently from the S&P 500 The S&P 500 and Dow Industrial Average have a lot to offer, but thinking beyond their pre-packaged forms could just make the difference between retiring, and retiring well.Ĭomments provided are informational only, not individual investment advice or recommendations.Since 1896, the Dow Jones Industrial Average has been a bellwether, but that doesn’t mean it’s the broadest market indicator This would be a terrible time to just blow off that idea and be complacent. They are different, even though they perform similarly much of the time. Think Carefullyīeyond S&P 500 and Dow performance is a bigger question: what type of reward and risk can you take on, now and in the future? That is a personal decision, but hopefully an informed one.

It forces you to invest the way the index is allocated, not the way you or a professional investor would likely arrange your stock positions. However, this is a big part of the problem with S&P 500 Index investing. When you set out to invest in stocks, I don’t think most of us think about weighting our stock positions the way either index does. Neither index has what I would call a very applicable weighting system for investors.
