One of the most famous of this group, Jeremy Grantham, penned a note on March 10 entitled “Reinvesting When Terrified” that encouraged investors to buy, suggesting stocks were 30% undervalued.
Since then, the market has roared ahead, without stopping for a correction of 10% or more. Standard & Poor’s 500-share index ended last week at 1026.13, up nearly 52% from its 12½-year low on March 9 and its highest close since Oct. 6. The Dow Jones Industrial Average is at 9505.96, up 45% since its March low.
Now, the chairman of Boston asset-management firm GMO and his colleagues say the S&P 500 has zoomed right past what they consider fair value of about 880, based on earnings estimates and historical price-to-earnings ratios.
Mr. Grantham sees “seven lean years” of a sluggish market ahead, to atone for what the firm believes was a long era of overpriced stocks, according to his newsletter.
