A raging bull is on the loose in China's stock market, which has just opened its doors to the world, but prospective New Zealand investors may want to approach the mega-rally with caution.
The Shanghai Composite, the mainland's largest stock index, rose 23 per cent in the 12 trading days to market close on Monday.
And it has risen more than 40 per cent since July 21, making the 8.25 per cent New Zealand's NZX 50 Index has gained over the same period look modest.
Chinese retail investors opened 370,000 new trading accounts in the last week of November and the rally has catapulted China's sharemarket ahead of Japan's to become the world's second-biggest, by value, behind the United States, according to the Economist.
Converging factors are driving what Chinese media have dubbed the "super-bull".
