Only two of the eight indexes on my world market watch, list posted a weekly gain. The top performing Shanghai Composite rose 2.04%, with Hong Kong's Hang Seng as a distant second at 0.46%. The losses of the other six indexes ranged from -1.05% to -2.84%, with the average of the eight at -1.10%, the worst since the -1.21% at the end of January.

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

Here is a table of the 2015 data performance, sorted from high to low, along with the interim highs for the eight indexes. Seven of eight indexes are in the green, with Germany's DAXK up over 20%. At the bottom of the list, India's SENSEX is fractionally in the red, the US's S&P 500 is up a tiny 0.10%.

A Closer Look at the Last Four Weeks

The tables below provide a concise overview of performance comparisons over the past four weeks (through year's end) for these eight major indexes. I've also included the average for each week so that we can evaluate the performance of a specific index relative to the overall mean and better understand weekly volatility. The colors for each index name help us visualize the comparative performance over time.

The chart below illustrates the comparative performance of World Markets since March 9, 2009. The start date is arbitrary: The S&P 500, CAC 40 and BSE SENSEX hit their lows on March 9th, the Nikkei 225 on March 10th, the DAX on March 6th, the FTSE on March 3rd, the Shanghai Composite on November 4, 2008, and the Hang Seng even earlier on October 27, 2008. However, by aligning on the same day and measuring the percent change, we get a better sense of the relative performance than if we align the lows.

A Longer Look Back

Here is the same chart starting from the turn of 21st century. The relative over-performance of the emerging markets (Shanghai, Mumbai SENSEX and Hang Seng) up to their 2007 peaks is evident, and the SENSEX remains by far the top performer. The Shanghai, in contrast, formed a perfect Eiffel Tower from late 2006 to late 2009.
