Asian stock market indices were trading mixed on Monday (31 October) with the Shanghai Composite down 0.19% at 3,098.34 as of 6.32am GMT. This followed concerns over the latest emails recovered related to Hillary Clinton and weak economic data released by Japan.

While the US reported better-than-expected GDP on 28 October, investors were more concerned of reports that revealed that the Federal Bureau of Investigation (FBI) would take another look at the emails of Democratic presidential candidate. The intelligence and security service is said to have obtained a warrant needed to begin reviewing the emails found on a laptop used by Hillary Clinton aide Huma Abedin and her estranged husband Anthony Weiner.

As the incident occurred just days ahead of the 8 November elections, analysts believe it could cause concern for investors, who expect that a win for Republican candidate Donald Trump could send stock markets crashing. "There seems little doubt that a Trump victory would trigger selling in stock markets from current levels...This has traders nervous as they start the week assimilating fresh news on Hillary Clinton's email problems," Rick Spooner, chief market analyst at CMC Markets was quoted as saying by Reuters.

Adding to the concern was the weak data reported by Japan's Ministry of Economy, Trade and Industry. Data released on Monday showed that Japan's industrial output was flat in September when compared to the previous month. Retail sales in the Asian country too were down 1.9% year-on-year. This marked the seventh straight month of decline, according to CNBC.
