After the main trend accelerates, divergence is likely to occur. Once a high point is broken, it becomes easier to avoid regulatory pressure. Coupled with the adjustment in US stock market's commercial aerospace sector on Friday, the current trading strategy is now very clear.

In the short term, the approach is still to switch back and forth around the main and auxiliary lines, or to perform high-low rotations within sectors. Fusion energy, consumer goods, robotics, and non-ferrous metals all have rotation potential. To be honest, these sectors have a lot of overlapping concepts; the key is to see which trend will activate first.
