Warren Buffett's Mentor Said Luck Drives Wealth: Should You Worry?

Buffett's mentor believed luck was the real wealth driver. That raises a brutal question about your portfolio strategy.

Here's the uncomfortable truth Wall Street doesn't want you sitting with: the guy who taught Warren Buffett — arguably the greatest investor alive — believed that luck, not skill, was the engine behind most great fortunes. That's not some fringe take. That's the intellectual foundation of one of investing's most respected minds.

Your savings deserve a strategy built on evidence, not a story built on survivorship bias. The best investors know the difference between a process and a result. Don't confuse the two with your retirement on the line. Continue reading at MarketWatch.com
