Lesson in how to be rational investors

A video of Song Hongbing being surrounded and attacked by some members of the audience as he gave a speech in Taiyuan, capital of Shanxi province, has gone viral on the Internet in recent days.

Members of the audience rushed to push and even hit Song, the author of the once-bestseller Currency Wars as they blamed him for their losses, which they claim was the result of induced investment in a non-ferrous metals investment exchange in Kunming, capital of Southwest China's Yunnan province.

The angry investors said that they invested in the exchange because Song supported investing in what was called the world's largest rare metals exchange when it was set up in 2011. In July, the exchange published a notice which showed it had a liquidity crisis.
