intro: While many people who have invested in the stock market or have mutual funds have seen a boost in their net worth this year, they have likely not seen anywhere near the bump these five people received.

The record-setting year gave us all-time highs for the major stock indices. The S&P and Dow Jones industrial average are on track for the biggest annual gains since the late '90s, while the Nasdaq reached highs not seen since 2000. Companies like Facebook, Google, Tesla and Priceline were top performers, to name only a handful.

Here's how some of the richest people in the country fared at the end of the year, compared with the start of 2013:
