(Bloomberg) -- Emerging-market stocks have set a new swath of record highs this week, driven by optimism over additional U.S. stimulus and a dovish Federal Reserve. The rally’s gaining momentum even as some technical indicators are showing a pullback is overdue.The MSCI Emerging Markets Index has now gained more than 9% this year, extending a rebound from its low during the coronavirus sell-off in March to a heady 88%. Goldman Sachs Group Inc., UBS Global Wealth Management and Wells Fargo Investment Institute all added to the positive chorus this week, releasing bullish calls on developing-nation equities.“With vaccine roll outs combined with fiscal stimulus and loose monetary policy, global growth should improve and benefit emerging-market economies relatively better,” said Joshua Crabb, a senior money manager in Hong Kong at Robeco, which oversees $186 billion. “Cheaper valuations combined with better growth, a dovish Fed and a weaker dollar bode well for emerging markets over the course of 2021.”Exchange-traded funds covering developing-nation assets drew the highest inflows in more than a year last week, with traders increasing their holdings by a combined $3.56 billion, according to data compiled by Bloomberg. Inflows went into stock ETFs, while bond funds suffered withdrawals. In total, that was an 11th straight week of inflows, increasing total assets to $332.1 billion, with the highest proportion of new money going to China, Taiwan and South Korea.‘Historical Highs’Emerging-market equities may reach new “historical highs” driven by better corporate profits, Goldman Sachs strategists including Kamakshya Trivedi in London and Caesar Maasry in New York wrote in a report this week.
