3 Stocks That Could Double Your Money

Just about any investor can double their money if they pick well-run companies -- or even a basket of companies -- and wait. An investment strategy as simple as buying an S&P 500 index fund and reinvesting the dividends has been a money-doubling bet over the past five years. Or, had you purchased shares of Amazon.com 18 months ago, you would be sitting on a double as well. If you have patience, doubling your money can be relatively easy.

Doubling your money in a relatively short time is much tougher. It typically involves investing in younger, less established companies that have lots of growth potential but could give a lot of ground if a few things don't swing their way. There are, though, some stocks that look like they have a double in them over a relatively short time frame, and three of our investing contributors think Spark Therapeutics (NASDAQ: ONCE), Tractor Supply (NASDAQ: TSCO), and American Tower (NYSE: AMT) fit the bill.
