An 18-year investment account prepared for my 1-year-old daughter｜Week 24 live trading record

The account fell below $1 million—I couldn’t hold on this time
I. Account progress
Principal: about 210k CNY
Last week total assets: about 1,274,978 yuan
This week profit/loss: -298,972 yuan
Current total assets: about 976,006 yuan
Cumulative profit: about 766,006 yuan
Simple return rate: about +364.8%
This week the account continued to drop further, leaving me with only a little over 970k. Compared with the earlier peak of more than 2.2 million, the account has already pulled back by more than half. A few weeks ago I could still see I was making quite a bit, but now most of the profits have already been given back.
Last week I already realized I had issues with my ability, patience, and discipline, but when facing continued downside for real, I still became too optimistic. In the end, the market gave me a harsh lesson.
II. This week’s trades
On Tuesday, when MUU dropped to around $643 and SNXX dropped to around $19, I couldn’t hold on. I closed the 2x leveraged longs on Micron and SanDisk.
After selling, I bought about 300k yuan worth of DRAM in the $59 to $61 range, hoping to reduce volatility first.
But after I sold, the market started to rebound.
Later, around $620, I bought back 10 shares of MUU. SNXX: I bought 1,000 shares around $21 and sold 800 shares at about $23. On Friday, after seeing the rebound, I also bought 10 shares of SanDisk’s common stock SNDK at around $1,850.
On Friday I also cleared my DRAM position. Hynix kept falling, and the performance of the U.S. stock ADR after listing was also below expectations. Since DRAM has a high weighting of Hynix, Samsung, and Micron, I finally chose to sell.
These trades may look cautious, but they were also quite chaotic. When the market fell, I was afraid it would keep dropping; when it rebounded, I was afraid I would completely miss out. Switching positions back and forth shows that my account’s up-and-down movements have been seriously affecting me.
No trades this week for the 2x leveraged longs on Hynix and Samsung.
III. About patience
This week my biggest takeaway is that I genuinely lack patience.
The buy price, sell price, unrealized profit, and unrealized loss in my account are, at the end of the day, numbers that constantly change. But once those numbers get bigger, it’s easy for people to let them control you.
When the market rises, you think the unrealized profit is your own money and you’re afraid to make less; when it falls, you feel like you’re losing every minute and you rush to do something.
But many mistakes in trading happen exactly because of this anxiety.
If I could be more patient—without frequently changing my judgment based on one day’s up or down—I might not have sold at the bottom, and then bought back again after the rebound.
I already know many of these principles, but the distance between knowing and doing is really huge. Investment patience is also hard to gain just by reading; it requires repeatedly practicing with real money.
IV. Re-understanding an investment portfolio
This week I spent some time reading “The Harbour”.
The account rose from 2.1 million to 2.2 million, then fell back to below 1 million, which made me re-understand the importance of an investment portfolio.
In the past, I cared more about the direction with the highest return, and I thought that if you get the main storyline right and concentrate your positions, wealth can grow faster. After this round of drawdowns, I started to realize that a long-term account also has to consider how to survive in different market environments.
A portfolio also isn’t just simply buying a few more stocks. I hold Micron, SanDisk, Hynix, and Samsung. On the surface it looks like several companies, but in reality they’re all concentrated in the same storage main theme. When the industry as a whole declines, they’re likely to fall together, so they can’t truly protect the account.
Going forward, I need to gradually build a more complete portfolio—considering what growth assets, cash, and protective assets should each be responsible for.
At the same time, I also need to learn to hold cash and wait for opportunities.
There aren’t that few drawdown opportunities in U.S. stocks. This year they’ve already shown up several times. There’s no need to keep fully invested during every period of rising prices. When you have cash, you only then get the choice when the market truly gives you an opportunity.
V. Weekly summary
This week the account lost nearly 300k yuan again, with a pullback of more than half from the historical high.
Last week I already recognized my problems, but this week I still hadn’t truly done what I should. After the market kept dropping, I sold at the low level; when the market rebounded, I became worried that I would miss out.
The market used real money to tell me that writing down reflections is easy, but changing your trading habits is hard.
I still believe in the long-term demand for AI and storage, but conviction can’t replace position management. What I need to learn more from now on is patience—waiting, reducing ineffective actions—and not letting the numbers in the account keep dragging me around.
This account is an 18-year cycle; it’s only week 24 so far. Continue recording, and start rebuilding my own investment system as well.
