LULU has been extremely weak since earnings earlier this year and it is not showing any signs of regaining strength. NKE has been getting hammered along with other names like Walgreens. It's a weak sector in a strong bull market.
The main point of this idea is to show that semiconductors and the mag 7 are carrying the market higher, but there are still a lot of other weak sectors with short opportunities. You reduce your risk substantially by shorting weak stocks and following the trend.
