History is littered with the remains of proclaimed, but unfulfilled, new eras. Exhibit 6 shows the long-run history for the Graham and Dodd P/E for the U.S. market. Over this time, we have witnessed some quite remarkable, and quite appalling, things – the deaths of empires, the births of nations, waves of globalization, periods of deregulation, periods of re-regulation, World Wars, revolutions, plagues, and huge technological and medical advances – and yet one thing has remained true throughout history: none of these events mattered from the perspective of value!
As Ben Graham wrote, “Let me conclude with one of my favourite clichés – the French saying: ‘The more it changes the more it’s the same thing.’ I have always thought this motto applied to the stock market better than anywhere else. Now the really important part of this proverb is the phrase ‘the more it changes.’ The economic world has changed radically and it will change even more. Most people think now that the essential nature of the stock market has been undergoing a corresponding change. But if my cliché is sound – and a cliché’s only excuse, I suppose, is that it is sound – then the stock market will continue to be essentially what it always was in the past – a place where a big bull market is inevitably followed by a big bear market. In other words, a place where today’s free lunches are paid for doubly tomorrow. In the light of experience, I think the present level of the stock market is an extremely dangerous one.”
I simply couldn’t have put it any better!
