They consider also a simple alternative portfolio similarly constructed from equal-capitalization weight deltas. If the delta for a country is positive (negative), the position in that country’s index is long (short), such that the overall portfolio is neutral. Using quarterly GDP measurements, monthly earnings-to-price ratio and dividend yield data and monthly dollar-denominated total stock index returns for 23 emerging markets spanning 1995-2008, they find that: (more…)
