Shocking Prediction: Why BP Could Be The Best Major Oil Stock To Own Right Now

I don't know about you, but when the stock market has had a virtually uninterrupted five year bull run I start to get a little nervous.

It is indisputable that stocks are much more richly valued today than they were five years ago. The S&P 500 itself is up 160% from the March 2009 low. There haven't been many times in history that the entire market has almost tripled in five years.

And while valuations don't necessarily matter in the short term, over the long term they most certainly do.

I'm not running around shouting that the "sky is falling," or anything like that, but I do believe that the easy returns have been made and it is time to start being more careful.

So how do we start being more careful? For me it means being a lot more picky about what stocks get into my portfolio. Making a mistake near a market top can be a lot more costly than making a mistake in a bull market.

To help me focus on only the very best ideas I like to troll through the portfolios of some of the world's greatest investors.

The way I figure it, if I focus on stocks that make it through the screening process of the finest investors in the world, then I've added another layer of extremely competent due diligence.

Yes it is true, even the great investors make mistakes. But they don't make many of them, so using a great investor portfolio as my starting point will definitely reduce my own error rate.

In the most recent quarterly filings I noticed one stock pick made by David Einhorn, of Greenlight Capital fame, that I thought deserved more attention.

Einhorn is one of the world's best hedge fund managers. He started Greenlight Capital with just $900,000 in 1996 and through exceptional stock picking has turned it into a $7 billion juggernaut.

More importantly to me, he runs a very concentrated portfolio and if an idea has made it through his screening process, I believe it is well worth consideration as an investment.

If it is good enough for Einhorn, perhaps it should be good enough for me.

Inexpensive, Fat Dividend and a Potential Catalyst

Of course everyone is familiar with BP (NYSE: BP). This is the company that was responsible for blowing out the Macondo deepwater well in 2010.

I remember the late spring of 2010 quite clearly. For weeks the entire world watched as the out of control Macondo well poured nasty black oil into the Gulf of Mexico.

CNN even kept a live feed of the well in the corner of its telecast at all times.

As a result of the disaster BP's shares cratered. More than three years later they still haven't fully recovered.
