Here’s a primer on how S&P 500 funds work, and whether they might work for you

For those would-be investors wanting to jump into the stock market but wondering which stock to buy, legendary investor Warren Buffett has a suggestion: Try buying 500 stocks instead.

Here’s an intro to how S&P 500 funds work, and whether one might be a good fit for your portfolio.

Today, 505 stocks constitute the index, since some of the 500 companies have more than one class of shares.
