The authors offer this explanation of the "the journey from hubris to humiliation" that emerging market equities have undergone:
Back in late 2010, when Sepp Blatter announced that Russia & Qatar would follow Brazil as hosts of the FIFA World Cup, both China & India were on course for >10% GDP growth, EM spreads were significantly lower, and the market cap of EM ($3.7 trillion on December 1st 2010) was twice the market cap of US banks, and exceeded the combined market cap of US tech & health care. Today, the market cap of EM equities is the same, while the combined market cap of US tech, health care and banks is over $10 trillion.
