Lai See | Was it a leak or a plant that moved the Shanghai Index?

Those of you who read the column by my colleague George Chen yesterday will have learnt of the conversation that occurred between Cheng Dinghua, an award-winning strategist at Essence Securities, and Xu Xiang, a fund manager at Zexi Investment, which ended up on the internet.
Investors were apparently shocked to learn that their private views differed markedly from what they were saying in public. Privately the two felt the Shanghai stock market would decline, whereas in public they were saying that Xi Jinping's new leadership was a buying opportunity and stocks would rise.
This conversation was supposedly leaked by a salesman, and the Shanghai stock exchange, which is largely driven by retail investors, has slipped back.
There is nothing new in this sort of thing. Internal e-mails from US investment banks several years ago described subprime mortgages as "crap", but they were nevertheless sold to clients with a more elegant description.
But the Shanghai conversation has attracted considerable online chatter. Some of this has been rather cynical and suggested that the conversation was not so much a leak as a plant, to enable those that did not get into the market earlier, to have another go.
What an absurd suggestion.
