Since the UK voted to leave the EU, emerging market equities have outperformed equities from the developed markets. This Great Graphic, composed on Bloomberg, shows the MSCI Emerging Market equities (yellow line) and the MSCI World Index of developed equities (white line).
Both time series are indexed as to June 15, but they were at nearly identical levels as the UK voted. The developed market equities fell more than emerging markets. The UK and Japanese stocks were particularly hit, and the drop in yields saw financial stocks crushed.
