@DouGiee you're super impressive! I gotta learn from you! 🌟📚
Digging up all these awesome ...

$NVIDIA (NVDA.US)$
Bought nvda.
$Advanced Micro Devices (AMD.US)$ Originally planned to buy more at 140, but couldn't make the move, so just tough it out. Changed to buy nvda. As long as the financial report is not adjusted downward, amd is already undervalued.
I originally wrote a long paragraph, and inexplicably it's gone, I don't know where the draft is saved. If anyone knows, please let me know, thank you very much. If no one knows, then never mind.
In short, the general idea is to persevere with proper allocation of defensive stocks, such as public utility companies that generate electricity from fossil energy. Inside XLU, I'm not happy with NEE, but the others are fine. I randomly bought a few the other day, and these days they are rising against the trend, showing strong support. However, they couldn't withstand the significant drop in big technology stocks, so overall I still suffered significant losses.
I believe the AI bull market is not over yet. If you also firmly believe in this, let's chant together, cast spells, and overcome the difficulties together:
Hold on tightly to high-quality stocks, don't sell unless fully loaded to the brim.
Hold on tightly to high-quality stocks, don't sell unless fully loaded to the brim.
Hold on to high-quality stocks tightly, not cutting is equivalent to fully bottoming out.
