Asian stock markets fell Monday as uncertainty about the outcome of the U.S. presidential election reduced appetite for riskier investments.
The race between President Barack Obama and Republican challenger Mitt Romney is virtually tied one day ahead of the election, generating an atmosphere of uncertainty that markets normally dislike.
Investors could awaken Wednesday without a clear winner. If the election comes down to a thin margin in a swing state like Ohio, the outcome could be delayed for days or weeks.
"The worst case scenario for markets is for a prolonged period of uncertainty if the results produce no clear cut result," said analysts at Credit Agricole CIB in Hong Kong.
