Argentina's presidential race is enticing some risk-taking investors to place bets despite the long odds that a new government can steer South America's second-largest economy out of its deep crisis. While most traders are waiting on the sidelines, anxious about the election and unsure of libertarian frontrunner Javier Milei, some daring bond investors are moving in. Their gamble is that a more market-friendly government is likely to emerge from the Oct. 22 vote, whether it is headed by Milei, Patricia Bullrich, the main conservative rival, or Economy Minister Sergio Massa, the candidate of the ruling left-of-center Peronist coalition.
