Here's One Warren Buffett Investing Strategy to Avoid

It's no secret that many investors regard Warren Buffett as one of the greatest investors of his time, and he's rightly earned that title.

While investors who've mirrored Berkshire's portfolio have fared well, its strategy is one you should be cautious of following -- mainly because of how top-heavy its portfolio is.

In Berkshire's most recent 13F filing, it was revealed that its top five holdings accounted for over three-quarters of its stock portfolio.
