The US is still positioned incredibly well even with uncertainty with the upcoming elections. Although for good or bad, the world economy likes consistency/incumbency and hates change, so a Trump loss alone could trigger it.
Simplistically; Our market isn’t really doing great all because of our own doing but also because the rest of the world’s markets aren’t good options whatsoever. So international markets are still heavily investing in the US market as it is the most stable of the options.
That said, even with a Trump loss and regime change; if no other developed economy steps up to show they are a more stable market, I could still see our growth continuing.
