Volatility on the MSCI Emerging Markets Index declined to the lowest since Sept. 9, according to data compiled by Bloomberg. Chinese stocks jumped, while the yuan fell amid signs China may be willing to tolerate a weaker exchange rate to help arrest an export slump.

South Africa's rand and bonds rallied ahead of the presentation of a mid-term state budget.
Optimism developing-market shares will extend a 15% rally in 2016 have been bolstered as investors see the Federal Reserve adopting a policy of gradual increases after a move in December. Mark Mobius, executive chairman of Templeton Emerging Markets Group, predicted Friday the Fed will raise rates "by a little bit but not excessively," while Clinton's odds of capturing the White House on Nov. 8 reached 91%, according to PredictWise.
"After months of uncertainties, the market is clearly pricing Clinton to win the next U.S. election and a Fed hike for December, but with limited Fed actions thereafter," said Regis Chatellier, a London-based strategist at Societe Generale SA, who favors bonds from Colombia, Mexico, Turkey and the Ivory Coast among developing-market sovereign international debt.

"Volatility tends to rise when markets are nervous and or unusually uncertain," said Tony Hann, the head of equities at Blackfriars Asset Management in London, whose Oriental Focus Fund has outperformed 94% of peers this year. "Certainty on U.S. elections has risen and nervousness about oil and China has diminished at the margin. Hence, there is lower volatility."
