The Biggest Risk to Warren Buffett's Portfolio

Few things have stood the test of time as well as Warren Buffett's investing prowess. Beginning with around $10,000 in seed capital in the mid-1950s, Berkshire Hathaway (NYSE: BRK.A)(NYSE: BRK.B) CEO Warren Buffett has seen his net worth climb to nearly $90 billion as of this past weekend. Had he not donated tens of billions of dollars over the years, there's a very real chance he'd have surpassed Amazon CEO Jeff Bezos as the richest man in the world.

In addition to creating wealth for himself, Buffett has also done a bang-up job for his shareholders. More than $400 billion in value has been created for Berkshire shareholders, even though Buffett's company doesn't pay a dividend.

Buffett's simplistic buy-and-hold ethos, coupled with his focus on just a few sectors of the market, is what's allowed him to be so wildly successful over the years.
