The Shanghai Composite has had a rough week, down 13.32% -- its 8th worst weekly decline in the past 25 years.
Any reasons this could be happening? Below looks at the Shanghai index over the past 20 years.
Over the past 52 weeks, the Shanghai has been up more than 130%. That huge gain was only surpassed by the rally into the 2007 top. The index met dual resistance this week, one of which came at the top of a 20-year channel and a resistance line drawn off key lows in 2006 and 2009.
Could this weakness spill over into markets in Europe and the States? This could be important as markets in Germany, London and France are breaking key support lines.
