World Markets Weekend Update: The Worst Week Of 2015

 | May 03, 2015 12:43AM ET

Six of the eight indexes on our world watch list traded lower this week, with China's Shanghai Composite as the top performer for the third consecutive week, gaining 1.89% in holiday shortened week. Hong Kong's Hang Seng was the other index to post a gain, albeit a modest 0.26%. The S&P 500 was the best performing loser, down only 0.44%. The losses for the other five index ranged from -1.20% for the FTSE 100 to -4.18% for France's CAC 40. The -1.34% weekly average of the eight is the worst collective performance of 2015.

The Shanghai Composite looks to be in bubble mode, up 95% from its interim trough in late October.

Here is an overlay of the eight for a sense of their comparative performance so far in 2015.
