MonitorIrrational financial markets disprove wisdom of crowds
Investors panic and sell shares over events like the US recovery and the slowing Chinese economy that should be welcomed, not feared

Anyone who still believes in the wisdom of crowds should take a look at what has been going on in the financial markets.
A market, after all, is made up of a crowd of investors, and its price fluctuations represent swings in the aggregate sentiment of that crowd.

But although prices impart this information with great efficiency, what the information tells us is that often the aggregate behaviour of a crowd of investors is not rational, let alone wise.
Just consider what has been happening recently in Asia's financial markets. Yesterday, Hong Kong's benchmark Hang Seng Index dropped by 2.2 per cent, bringing its cumulative fall over the past four weeks to 11 per cent.
It is not just Hong Kong's market that has taken a hammering. Mainland stock markets are down. too. And in Southeast Asia, share prices, bond markets and currencies have all fallen steeply.
