Edit: Also, I'd guess that once the tech stock prices started tumbling, it caused a lot of people who have nothing to do with the carry trade to sell, causing further price decline.
For the US, I think there are two major possibilities.
1: unemployment spikes which leads to the Fed lowering rates significantly which leads to more money floating around which leads to higher stock markets.
2: the unemployment goes back to normal, which puts the stock market back to normal.
Both presidential candidates have loose money platforms and neither have plans to balance the budget (Trump through tax cuts, Harris through spending). Balancing the budget would result in tight money which would destroy the stock market. And since the American public thinks stock market == economy, it's not going to happen.
