If there’s one industry that attracts an unusual number of snake oil salesmen, it’s probably this one.
Spending some time around markets eventually reveals the economist who knows what’s coming next, the fundie who has discovered a secret that somehow remains hidden from every other investor on the planet.
In most professions, expertise can be observed directly. We assume the surgeon knows more about surgery than we do and the pilot knows more about flying. Investing is different. It may be one of the few areas where a healthy dose of scepticism is necessary to succeed.
However, I do believe there are a handful of exceptions to this.
For me, Warren Buffett is one of them. But it’s not just due to his extraordinary track record.
It’s that he occupies a peculiar position in this industry. As one of the most successful practitioners of the game, he has spent decades telling people not to play it the same way he does.
Most financial figures are sellers of some description, whether it’s a newsletter, a new fund or at the very least, a world view. And before throwing stones from a glass house, I should acknowledge the irony here. My career exists within this very realm.
The point isn’t that selling ideas is inherently bad. It’s that authority is often derived from the ability to persuade people that you know something most don’t.
Buffett's authority stems from almost the opposite impulse.
How many Michelin-starred chefs would tell people they could make the same dish at home, for a fraction of the cost? There's an almost self-negating quality to Buffett's credibility.
Below are some of my favourite takes from him.
"By periodically investing in an index fund, for example, the know-nothing investor can actually outperform most investment professionals."
Coming from one of history's most successful active investors, the statement borders on paradox.
In 2008 Buffett famously made a $1 million bet that an S&P 500 index fund would outperform most investment professional’s picks over a 10-year period. And indeed, he was right. Ted Seides, co-founder of Protégé Partners, accepted the challenge and handpicked five hedge funds he believed would outperform the S&P 500 over this period. The performance gap was certainly something.

This exercise wasn't intended to be an obituary for active management. Rather, it was an exercise in humility for an industry that has long projected an image of delivering superior returns through complex strategies, demanding higher fees.
“The goal of the non-professional should not be to pick winners – neither he nor his ‘helpers’ can do that – but should rather be to own a cross-section of businesses that in aggregate are bound to do well. A low-cost S&P 500 index fund will achieve this goal.”
I believe the ‘helpers’ he refers to here are “those who profit from giving advice or effecting transactions”. I imagine many readers have successfully invested in individual companies for decades and have the results to show for it.
But no matter your persuasion, the ability to consistently identify winning stocks over decades is extremely difficult, even with professional help. The argument is ultimately about probability rather than possibility.
“The most important quality for an investor is temperament, not intellect.”
Buffett's point challenges the common perception that investing is primarily an intellectual exercise. It also echoes Peter Lynch's observation that the most important organ in investing is the stomach, not the brain.
Lacking a 'superior' intellect is not the barrier many make it out to be. Long-term success is often determined more by the ability to remain disciplined and stick to a sensible process through periods of uncertainty.
Every generation produces its own collection of gurus, visionaries and occasionally outright charlatans. However, the promise of exceptionalism always gives way to the decidedly unglamorous virtue of common sense.
