The Hong Kong stock market is too strong, be cautious with day trading.

Last night, U.S. stocks plummeted, and those playing the U.S. stock market probably didn't have a good time. Looking at the indices, the Nasdaq only dropped 1.24%, which didn't feel like much.

Let's check the individual stock declines. Below are the U.S. stocks I follow closely. Feel the drop in U.S. stocks last night:

My U.S. stock positions are low now, so the drop is just entertainment. However, my current principle is not to add positions too frequently. The price for adding positions must be significantly lower than the last purchase price, say 8%-10% below the previous drop.

Most importantly, control the position size for individual stocks—don't let it get too high. I think as long as you manage the rhythm well, U.S. stocks aren't too risky; they have strong recovery capabilities.

The happiest thing today is the surge in Hong Kong stocks:

In this round of the Hong Kong stock bull market, China-concept ETFs have risen 40% since the bottom on January 13 this year. Everyone is feeling good this time.

Recently, due to the high volatility of China-concept ETFs, I've done a lot of day trading. While I succeeded many times before, today's strong Hong Kong market taught me a lesson:

Here's my recent overall trading rhythm:

I missed out on a lot, but there's no point regretting it. Even if I went back, I'd still sell according to my own rhythm.

In this wave of Hong Kong stock surges, China-concept stocks have already surpassed last year's post-National Day peak by 6%:

Recently, due to the frenzy over Mixue Ice City's IPO, Nayuki's stock price soared, up 33% today:
 

Seeing Nayuki brings back bad memories. Back then, I participated in Nayuki's IPO, got allocated shares, didn't sell in the gray market, got greedy, and the rest is history—I ended up selling at a loss.

If I had sold Nayuki in the gray market, I could have made about 1,000 yuan per lot. That's how Hong Kong IPOs are—subscribe but don't hold; sell in the gray market at the latest, or on the first trading day.
