Reversion To The Mean
Jeremy Grantham is the co-founder and chief investment strategist of Grantham, Mayo, & van Otterloo, more commonly known as GMO. He is best known for his quarterly newsletters and for popularizing the ‘reversion to the mean’ concept in investing. He has also predicted key turning points in market indices and was listed by Bloomberg Magazine as one of the 50 most influential people in global finance.
Mean reversion, as employed by GMO, is similar to value investing. The difference is that where conventional value investors use company-specific fundamental data to assess valuations, GMO uses history as a guide.
Grantham and the GMO team spend a lot of time analyzing stock market valuations and bubbles throughout history. They use long-term valuation trends to calculate what they believe to be the fair value of an asset. They then invest in assets that have moved a long way below fair value.
Grantham believes strongly that history repeats itself and that every bubble eventually bursts. He used his knowledge of bubbles to predict the dotcom bubble in 2000 and the housing bubble in 2007. He also managed to get his clients out of Japanese equities when they peaked in the late 1980s.
The nature of Grantham’s approach is that GMO tends to underperform during bull markets and then outperform when markets correct. Unsurprisingly, over the past few years, the firm’s funds have underperformed many of their peers. As a result, the firm’s clients have reportedly withdrawn $40 billion since 2014.
