Many readers will know Warren Buffett as one of the world’s top investors. The Oracle of Omaha strikes us as sharp, witty and don’t forget he has a photographic memory. Many people buy a stock just because Buffett bought the very same stock. But fewer people realise that this blind, unquestioning faith in heroes once got him into a spot of bother… way back in 1950. At the time, Buffett idolised Ben Graham and David Dodd, the founding fathers of value investing. He had memorised their textbook, Securities Analysis, and later admitted, ‘I knew the book even better than Dodd.’

Warren was still a student at Columbia, networking to improve his job prospects. Through a chance encounter, he found himself having lunch with a man called Lou Green, one of Ben Graham’s business associates. They bounced investment ideas.

Lou Green asked, ‘Why did you buy Marshall-Wells?’

I looked at brokers’ price targets and made one of two conclusions:

  • If a stock was trading at a discount - i.e. below the broker's target - I assumed brokers were optimistic and bullish. I saw a buying opportunity;
  • If a stock was trading at a premium - i.e. above the broker's target - I assumed brokers were pessimistic and bearish. I saw a selling opportunity.

Everything seemed clear and actionable. I absorbed broker targets with the same level of trust as someone following…
