The FT's David Keohane's Shorter Jeremy Grantham

From Mr Keohane's Twitter feed:

Grantham's latest: "A range of 9 to 18 months from today and a price rise to around 3,400 to 3,700 on the S&P 500 would show the same 60% gain over 21 months as the least of the other classic bubble events." https://t.co/iu6cXIHRxW
