Jeremy Grantham

Grantham was born in Ware, Hertfordshire[6] and grew up in Doncaster.[7] He studied Economics at the University of Sheffield. In 1966 he completed an MBA at Harvard Business School.[8]

Grantham's investment philosophy can be summarised by his commonly used phrase "reversion to the mean." Essentially, he believes that all asset classes and markets will revert to mean historical levels from highs and lows. His firm seeks to understand historical changes in markets and predict results for seven years into the future. When there is deviation from historical means (averages), the firm may take an investment position based on a return to the mean. The firm allocates assets based on internal predictions of market direction.[9]

Grantham has built much of his investing reputation over his long career by claiming to identify speculative market "bubbles" as they were unfolding. Grantham claims to have mostly avoided investing in Japanese equities and real estate in the late eighties, as well as technology stocks during the Internet bubble in the late nineties.

In GMO's April 2010 Quarterly Letter Grantham spoke to the tendency for all bubbles to revert to the mean saying:

For the record, I wrote an article for Fortune published in September 2007 that referred to three "near certainties": profit margins would come down, the housing market would break, and the risk-premium all over the world would widen, each with severe consequences. You can perhaps only have that degree of confidence if you have been to the history books as much as we have and looked at every bubble and every bust. We have found that there are no exceptions. We are up to 34 completed bubbles. Every single one of them has broken all the way back to the trend that existed prior to the bubble forming, which is a very tough standard. So it's simply illogical to give up the really high probabilities involved at the asset class level. All the data errors that frighten us all at the individual stock level are washed away at these great aggregations. It's simply more reliable, higher-quality data.[10]

In his Fall 2008 GMO letter, Grantham commented on his evaluation of the underlying causes of the then-ongoing world credit crisis

To avoid the development of crises, you need a plentiful supply of foresight, imagination, and competence. A few quarters ago I likened our financial system to an elaborate suspension bridge, hopefully built with some good, old-fashioned Victorian over-engineering. Well, it wasn't over-engineered! It was built to do just one under favorable conditions. Now with hurricanes blowing, the Corps of Engineers, as it were, are working around the clock to prop up a suspiciously jerry-built edifice. When a crisis occurs, you need competence and courage to deal with it. The bitterest disappointment of this crisis has been how completely the build-up of the bubbles in asset prices and risk-taking was rationalized and ignored by the authorities, especially the formerly esteemed Chairman of the Fed. ...[11]

I ask myself, 'Why is it that several dozen people saw this crisis coming for years?' I described it as being like watching a train wreck in very slow motion. It seemed so inevitable and so merciless, and yet the bosses of Merrill Lynch and Citi and even U.S. Treasury Secretary Hank Paulson and Fed chairman Ben Bernanke – none of them seemed to see it coming.

I have a theory that people who find themselves running major-league companies are real organization-management types who focus on what they are doing this quarter or this annual budget. They are somewhat impatient, and focused on the present. Seeing these things requires more people with a historical perspective who are more thoughtful and more right-brained – but we end up with an army of left-brained immediate doers.

So it's more or less guaranteed that every time we get an outlying, obscure event that has never happened before in history, they are always going to miss it. And the three or four-dozen-odd characters screaming about it are always going to be ignored. . . .

So we kept putting organization people – people who can influence and persuade and cajole – into top jobs that once-in-a-blue-moon take great creativity and historical insight. But they don't have those skills.[11]

Grantham focused on the issue of personal traits and leadership in trying to explain how we reached the current economic crisis.

Grantham has repeatedly stated his opinion that the rising cost of energy – the most fundamental commodity – between 2002 and 2008 has falsely inflated economic growth and GDP figures worldwide and that we have been in a "carbon bubble" for approximately the last 250 years in which energy was very cheap. He believes that this bubble is coming to an end. He has stated his opposition to the Keystone Pipeline on the basis of the ruinous environmental consequences that its construction will bring to Alberta and to the entire planet due to the contribution that burning the extracted oil would make to climate change.[2][12]

Grantham is known to be a strong advocate for investments in the timber industry that also relies on trees for biomass/biofuel (wood chips).[13][14][15][16] The potential conflict of interest with Grantham's philanthropic engagement for the "beyond coal" campaign of the Sierra Club[17] was criticized in Jeff Gibbs' documentary Planet of the Humans.[18]

Grantham, together with his wife Hannelore, established the Grantham Foundation For the Protection of the Environment in 1997. Substantial commitments have been made to Imperial College London, the London School of Economics and the University of Sheffield, to establish the Grantham Institute - Climate Change and Environment, the Grantham Research Institute on Climate Change and the Environment and the Grantham Centre for Sustainable Futures, respectively, which will enable the institutions to build on their extensive expertise in climate change research.[19] The 2011 tax filing for the Grantham Foundation for the Protection of the Environment shows the Foundation donated $1 million to both the Sierra Club and to Nature Conservancy, and $2 million to the Environmental Defense Fund that year. The Foundation has also provided support to Greenpeace, the WWF, Rare and the Smithsonian. From 2006 to 2012, The Grantham Foundation for Protection of the Environment funded a $75,000 prize for environmental reporting. The prize was administered by the University of Rhode Island's Metcalf Institute for Marine & Environmental Reporting.[7][20]

In August 2019, he dedicated 98% (approximately $1 billion) of his personal wealth to fight climate change. Grantham believes that investing in green technologies, is a profitable investment on the long run, claiming that decarbonizing the economy will be an investing bonanza for those who know it’s coming.[21]

Grantham was appointed Commander of the Order of the British Empire (CBE) in the 2016 Birthday Honours for philanthropic service to climate change research.[22]
