Do you get confused about investing in the stock market, even if you want to stick to a simple strategy like passively buying an S&P 500 index fund? There are various factors to consider, like the equal weight index.

The S&P 500, or Standard & Poor’s 500, is an index representing the performance of 500 large companies listed on U.S. stock exchanges.

It’s considered an indicator of the U.S. economy and a benchmark for many investors. I’ve been investing in the index for years, and it’s the perfect way to get exposure to the stock market.

However, some people tend to make a simple strategy like a complex one.

That’s because there’s more than one way to invest in this index.

  1. The market-cap-weighted S&P 500 (which is the default for ETFs like VUSA or VOO)
  2. The equal weight S&P 500 (which is what some people recommend)

In this article, we’ll dive into what the S&P 500 is, how the market-cap-weighted index works, and what the equal weight index entails.
