What Is the S&P 500?

The S&P 500, short for the Standard & Poor’s 500, is a stock market index gauges the performance of 500 large companies listed on U.S. stock exchanges. It is considered a leading indicator of the overall U.S. equity market.

Imagine we’re chilling, and I ask you, “What’s the temperature outside?” You check your phone, and you tell me, right? That’s because your phone checks a thermometer representative of your general area.

Now, apply that concept to the U.S. stock market, which, my friends, is the S&P 500. It’s like the thermometer of the U.S. stock market. But instead of checking the temperature, it’s checking the performance of 500 of the biggest, most stable companies listed on the stock exchanges.

These companies are from all sectors of the economy – we got tech giants, big pharmaceuticals, energy behemoths, all the heavy hitters. The S&P 500 takes all these companies and makes an average of a ‘financial temperature’.

Now, you might ask, why 500 companies? Why not 100 or 1000? The 500 companies that comprise the S&P 500 cover about 80% of the U.S. equity market by capitalization. That means it’s giving you a pretty accurate reading of how the market’s doing.

When people say, “The market is up today,” they usually talk about this bad boy. It’s a benchmark, a reference point for investors to compare their returns against. If you’re beating the S&P 500, you’re doing well.

But remember, even though the S&P 500 has these big, stable companies, it can still go up and down. It reflects the market and the economy; we all know how unpredictable those can be. So as always, invest wisely and do your homework before you put your money in. Just because it’s got a cool name like S&P 500 doesn’t mean it’s a sure thing.
