My US stock holdings hit a new high today. I didn't spend much time researching the stocks. I simply bought hot stocks when they plummeted and sold them when they surged. The main reason for the doubling of my holdings is that Tesla is my largest holding, while many other stocks have doubled. The entry point from April this year to now is a rare, once-in-a-few-years rally in the US stock market. Technical skills are unnecessary. These good times won't last long; everyone's betting on when the drumbeat will stop.
