Stocktake: Stock markets are ignoring rising risks, says Grantham

Investor expectations are ‘achievable but optimistic’ – GMO founder, veteran investor

"One of the most impressive mismatches in history." That's how GMO founder and veteran investor Jeremy Grantham describes the current market in his latest quarterly letter, warning the current US market valuation is in the top 10 per cent of its history even as the US economy is in its worst 10 per cent, "perhaps even the worst 1 per cent".

GMO has reduced its net equity exposure from 55 to to 25 per cent, near levels it hit during the global financial crisis. Now, bulls could point out that Grantham and GMO have been too cautious for most of the last decade. Still, it’s hard to argue stocks aren’t richly valued. The S&P 500 trades on 21.5 times expected earnings for the next year, according to FactSet, the highest level in 18 years.

Goldman Sachs says stocks can justify today’s levels if earnings rebound strongly in 2021, although they look substantially overvalued if earnings disappoint. Investor expectations are “achievable but optimistic”, says Goldman, but even meeting these high expectations would “validate” current prices rather than push them substantially higher.

There is, then, little room for error, despite the investment landscape being dotted with obvious “medical, economic and political risks”.


GMO is often criticised for being too bearish, but the overall valuation picture would seem to confirm this is, as Grantham puts it, a time for “caution and patience”.
