The Chinese stock markets have experienced significant turmoil in recent weeks, with the Shanghai Composite Index – the country’s major reference – falling by 32% since June 12. But this fall was preceded by an equally sharp rise of 150% over the previous nine months. In the 20 years since I have been working in finance, I’ve never seen anything like this. So what is going on with the Chinese stock market?
There are several reasons for this unusual behaviour: firstly, when I teach stock market investment to my Chinese students, I always remind them that the Shanghai stock exchange should be thought of more as a casino, rather than as a proper stock market. In normal stock markets, share prices are – or, at least, should be – linked to the economic performance of the underlying companies. Not so in China, where the popularity of the stock market directly correlated with the fall in casino popularity.

In China, given the low credibility of the financial statements published by listed companies, investors need to rely on other tools to predict share price performance. These tools include a heavy reliance on technical analysis and charts – a method that tends to predict future share price based purely on the company’s past performance, with no regards to its fundamentals. Even the name of the company is often neglected; all that matters is the historic price performance.
While this technique is also used in Western markets, my experience in China is that it is the predominant method for investment. Hence the disconnect between a share’s price movements and economic fundamentals.
