As an exercise in understanding market volatility, we recently introduced the dispersion-correlation map to see how volatility manifests in dispersion and correlation. We saw very high levels of correlation at the beginning of January for both the S&P 500 and S&P Europe 350; the S&P Pan Asia BMI also sat at above average correlation then. We’ve often said that high correlations indicate fragile markets, as indicated by the sharp declines that took place in the following month for all three indices.
Following the results of the June 23rd Brexit referendum, volatility spiked around the globe. In the U.S., correlation is almost as high as it was at the beginning of the year, and dispersion is slightly higher. Similar readings can be seen in Pan Asia where correlation is high but dispersion is below average. The situation in Europe is different. As of the end of June, dispersion for the S&P Europe 350 was well above average, as was index correlation.
Paradoxically, wider dispersion in the S&P Europe 350 also means that there are more places to hide. Current European dispersion levels reflect considerable room to add (or subtract!) value by stock or sector selection.
Heightened correlations make for fragile markets. Investors in the U.S., Europe, and Asia should prepare for the possibility of a rough ride.
