Investors who can find tomorrow's big winners today can grow even modest investment portfolios into life-changing wealth. The Motley Fool Stock Advisor service has delivered winning investment ideas to its subscribers since 2002, and its track record of more than tripling the return of the broad-based S&P 500 stock market index has given subscribers a huge advantage over their peers. Now, you can get access to this award-winning service at a discounted price of as little as just $99 a year. Below, we'll give you a special discount to get in on Motley Fool Stock Advisor, but first, let's take a look at why the service is worth every penny.

Discovering the market's most lucrative stock picks

Becoming a successful investor requires getting an edge on the rest of the investing community, and one way to prosper with your investing is to look for stocks that have the potential to produce high long-term returns. Unlike most investors with timeframes of months or even days, having a long-term mindset will let you pay attention to the underlying business supporting the stock rather than the stock price itself. That in turn can help you pick up much larger returns than the tiny wins that short-term traders try to eke out.

What Motley Fool Stock Advisor does is to focus on finding stocks that have the best chance of outperforming the broader stock market over the next three to five years. The service looks for stocks in a diverse set of industries that have strong management teams, strategic vision, and an underappreciated story among most investors. Stock Advisor also follows a disciplined, unemotional approach and makes sure to keep track of its results to remain accountable to its subscribers. Most importantly, the service incorporates the Foolish ideal of keeping investing entertaining and fun as well as profitable.

Winning Motley Fool stock picks -- at a discount!

When you look at the track record that Motley Fool Stock Advisor has put together, you'll see how these philosophies can produce strong returns. The service was ranked No. 3 in industry analyst Mark Hulbert's five-year rankings of more than 200 investment-advisory services, according to The Wall Street Journal.

One of the keys to the service's success has been picking great stocks and never settling for anything less than earth-shattering long-term returns. Buying (NASDAQ:AMZN) in 2002 has given Stock Advisor members returns of almost 5,000%, even as many investors who have owned Amazon over the years have contented themselves with far smaller gains. Similarly, many investors sold out of early Stock Advisor pick Marvel Entertainment when Disney (NYSE:DIS) bought the company for $4 billion seven years ago, but much of Stock Advisor's roughly 4,750% return has come after the buyout, as members took full advantage of the House of Mouse's growth opportunities and subsequent acquisitions.
