(Bloomberg) -- Emerging-market stocks gained the most in three weeks and Mexico's peso led currencies higher as traders weighed the odds of a victory for Hillary Clinton in Tuesday's U.S. presidential election.

Developing-nation investors perceive a Clinton win as positive after Republican candidate Donald Trump put forward anti-trade pledges that may affect ties with Mexico and China. The peso, which headed for its biggest one-day gain against the dollar since September, has been considered a barometer for investors' views on Trump's chances in the election. A final Bloomberg poll released Monday pointed to a slim lead for Clinton, while the FBI a day earlier reaffirmed that Clinton's use of private e-mail servers wasn't a crime.
