If you listen to a lot of experts on Wall Street, they'll say the markets are horrified that Donald Trump might be president.
It could be a widespread disaster for the market, according to many commentators. One trader suggested the S&P 500 would fall by 50 percent if Trump has the chance to implement his economic policies.
And yet, the data suggest that the market doesn't actually care at all.
Trump's chance of winning the presidency shifts with news events and primary results on a daily basis, according to the implied odds on the PredictIt betting market, but the market doesn't seem to react to those changes.
The day-to-day movement of the S&P 500 shows no sign of correlation with Trump's odds of winning.
