Mexico country-specific exchange traded funds are strengthening on Republican nominee Donald Trump’s misfortunes as traders use Mexican assets as an election barometer to gauge the likelihood of a Democratic runner Hillary Clinton win.

On Monday, the iShares MSCI Mexico Capped ETF (NYSEArca: EWW), which holds broad range of companies in Mexico, jumped 3.8% and SPDR MSCI Mexico Quality Mix ETF (NYSEArca: QMEX), which tracks a more customized basket of Mexico stocks that were selected based on metrics like value, quality and low volatility, gained 3.0%. Both EWW and QMEX are now trading back above their 50- and 200-day simple moving averages.

Mexican assets rallied Monday, with the peso currency up 2.3% to a one-month high of 18.8608 per dollar earlier in the day, after Trump dismissed his vulgar comments on a leaked 2005 video as “locker room talk,” Bloomberg reports.

Mexican markets, notably the peso, has acted as a barometer of investor anxiety over the November elections, weakening when Trump advanced in polls and strengthening when the Republican nominee lost ground.

Trump has questioned NAFTA and free trade, vowed to add tariffs on Mexican imports, pledged to deport millions of undocumented immigrants and wanted to build a border wall to keep out Mexican immigrants, adding to price volatility in the Mexican peso in recent months. The peso was one of the most undervalued emerging market currencies in recent weeks and has acted as a bellwether of developing market sentiment to the likelihood of a Trump presidential win.

However, in the wake of the video in which he talks about groping women and seducing a married woman, Trump has lost momentum, with some Republican party members calling for the runner to quit the race.
