Bill Nygren’s Devil’s Advocate Rule: How to Avoid Costly Investing Mistakes

During his recent interview with the RWH Podcast, Bill Nygren dismisses the notion that value investing is obsolete, despite its decade-long underperformance. “The idea that value would be out of favor for a decade is something that was never something we envisioned back in the eighties or nineties,” he admits.

Yet he sees opportunity in today’s extremes: “We’ve never seen such issue-specific or industry-specific concentration in the S&P500. It’s effectively become a mega cap, a concentrated mega cap growth fund.”

His counterargument is rooted in capitalism’s inevitabilities: “High returns will draw competition and it will force companies and industries back to fair levels of pricing.”

Nygren’s framework is simple but rigorous: “We want a large discount to underlying business value… We want the combination of dividend income and expected per share value growth to at least match what we expect for the S&P500… [And] we want exceptional management.”

He emphasizes alignment: “Exceptional largely means that they are aligned with outside shareholders in having a goal of maximizing intermediate to long-term per share business value.”

To combat overconfidence, Nygren borrows from Michael Steinhardt’s playbook: “We’ve intentionally tried to avoid [groupthink] by doing team-oriented decision-making.”

Every new idea faces a “devil’s advocate review,” where analysts must defend against critiques. “We want the path of least resistance to be our mistakes exit the portfolio rather than mistakes linger,” he explains.

When fundamentals diverge from expectations, Harris shifts coverage to fresh eyes: “The initial analyst is probably too anchored on their original forecast… [and] has probably lost their voice.”

Nygren warns against extrapolating recent growth trends: “To believe that growth investing is going to succeed at the expense of value investing for the next decade, you have to believe that [outperformance] continues.”

He calls this “a bet against capitalism,” noting that even giants face gravity: “We’re starting at a level where we’ve never seen such… concentration.”

Reflecting on his longevity, Nygren credits teamwork: “This isn’t a job to do as a one-person operation. Even Warren Buffett needed help.” His advice to investors? Stay patient, stay skeptical, and trust the process: “If you’re going to stay successful at this business next year, you have to be smarter than you were this year.”
