The Year of the Snake is considered one of the less auspicious in the 12-year Chinese zodiac cycle. And 2013 is the year of the Black Water Snake, which comes around once every 60 years and is seen as the least fortuitous. How China's stock markets turn out after years of poor performance remains to be seen but the snake is providing banks and asset managers with plenty of food for thought. Many of them have been gazing into the crystal ball to see what 2013 may hold for Chinese markets.
