You have a set of stocks either correlated with the U.S. economy or China's economy.
Amateurs tend to pick uptrending correlated stocks (all stocks trending up in the U.S.). When U.S. economy crashes, all their eggs are in the same basket.
If you'd tell the amateurs to pick the inverse, they'd go for downtrending Chinese stocks. When China's economy crashes, all their eggs are still in the same basket.
I think what you are looking for instead, is contrarian trading strategies. Here you follow counterstrategies to what the large herd is doing. A good contrarian strategy for buying bitcoin, may be to gauge crypto sentiment on HackerNews. If the majority is gleeful or pessimistic, the price is too low for future value, if articles get posted on how to build your own blockchain in Python, then you should be ready to start converting to money, because one month later, every smart nephew's uncle fomo-bought and panic-sold the hype and caused a crash or depression. Similarly, if the U.S. president is glowing about the heated economy, and dismissive of China, this opens up new profitable options for contrarian traders (which are less risky/more informed than completely random or following the herd).
