Jeremy Grantham, who is credited with calling the 2000 and 2008 downturns, has warned investors to be prepared for the possibility of a near-term "melt-up" that would likely set the stage for a burst bubble and a stock-market meltdown, MarketWatch reports.

In a 13-page note that he emphasised reflected "a very personal view," the value investor and co-founder and chief investment strategist of Boston-based asset manager GMO compared the present market setup with the run-up to past bubbles, including the 2000 tech boom and the precursor to the 1929 crash.
