These 'Black Sheep' Stocks Beat The Market 4-to-1

You may or may not have heard of renowned money manager Joel Greenblatt.

Over an illustrious career spanning more than twenty years, the Gotham Capital hedge fund manager racked up annualized returns of 40%, eclipsing the success of even his mentor, Warren Buffett.

Investors who were on board with Greenblatt for his entire tenure at Gotham would have seen a $10,000 investment balloon to more than $8 million, earning 800 times their initial stake.

His remarkable track record didn't happen by sheer luck, but rather through his focus on investing in a unique group of companies that shared one commonality.

Industry leaders like American Express, Liberty Media, Allstate, Expedia and Kraft Foods all carry this trait. And they each helped Greenblatt and fellow investors make millions...

These companies are just a few of a long list of spin-offs that all once belonged to larger parent companies. And they all flourished after leaving the nest.

Take spin-off biopharmaceutical maker AbbVie (NASDAQ: ABBV) for example. Since officially leaving its parent company, Abbott Laboratories, in January 2013, ABBV has risen more than 65%... beating the market by roughly 30%.

Here's another example. Just over two years ago, ConocoPhillips separated its upstream oil and gas production from its downstream refining operations to create two distinct companies. Shares of Phillips 66 (NYSE: PSX) were distributed to investors of ConocoPhillips and have since gone on to nearly triple in value, a healthy increase of 180%, compared to a return of just 45.4% for the S&P.

The success or these spin-offs aren't just isolated incidents. In fact, this phenomenon has been tested numerous times over the years with compelling results. One of the most famous studies was conducted by consulting firm McKinsey in 1999. McKinsey reviewed 168 restructurings over a 10-year period and found that shares of spin-offs produced annualized gains of 27% in the 24 months following separation, versus a 17% gain for the S&P 500.

That performance could have turned a $10,000 investment into more than $109,000 over 10 years against just $48,000 in a S&P 500 index fund. And that's taking the good with the bad -- without any effort made to identify the best-positioned spin-offs offering the most potential.

Skeptics might say that the results are skewed by a handful of big winners. But the facts say otherwise. A Lehman Brothers study between 2003 and 2006 found that two-thirds of all spin-offs went on to outperform the market. And since 2003, Bloomberg's Spin-Off Index has beaten the market 4-to-1.
