According to BBC World News, the stocks in the US that are expected to do well under Trump are surging. I think those stocks are surely over-valued. Their value will be corrected after Trump loses.
In the US it’s illegal to bet on elections(see update), but betting on the stock market is fair game. I would love it if the some short-sellers would exploit this situation.
(update) It’s now legal to bet on elections in the US, as of a few weeks ago
A month ago you would have been wrong. But indeed apparently this just changed:
“Election bets were approved legally just weeks ago, as the 2024 race headed into its home sprint.”
