Warren Buffett's 5 Favorite Stocks

It might be the most controversial statement I've ever told investors...

In fact, you're likely to shrug me off at first, as what I'm about to tell you goes against everything you've been taught about wealth management.

But if you want to become wealthy in the stock market, then it might be the single most important thing you'll hear.
 
I think diversification actually hurts your returns.
 
I'm not saying you should have a portfolio of just two or three holdings. That's never a good idea. If one of those stocks heads south, then your entire portfolio would suffer.
 
But at the same time, I'm not at all concerned with having a portfolio of dozens of holdings that represent every sector of the market. After all, it's impossible to outperform the market if your portfolio is the market.
 
Think of it this way: Which do you think would average higher on a test... an entire class full of students, or a handful of the smartest students as picked by the teacher? The answer is obvious... and it's the same with your portfolio.
 
What may surprise you is that I'm not alone in thinking this way.
 
Warren Buffett's Berkshire Hathaway (NYSE: BRK-B) holds just 34 publicly-traded U.S. stocks. That's a lot for an individual investor, but for a company with billions at its disposal, it's surprisingly few. On top of that, Berkshire's top five holdings make up 75% of its portfolio.
