Today’s US stock market was like a roller coaster. Within a single day, we saw a sharp pullback followed by a strong full recovery.

❌ One mistake made:
I let emotion take over on Monday, chased highs and bought blindly, losing 300€.
See my homepage
✅ One right decision:
On Tuesday, positions dropped nearly 10% across the board. My floating profit shrank to only 400€ at one point, almost back to square one. After careful consideration, I chose to hold and refused to cut losses. The market rebounded sharply near the close, recovering 1,400€ in just one hour.

I got a little overconfident with last week’s 2,100€ floating profit. After adding funds on Monday, I allocated my positions:
- Long-term holdings in great companies: bought TSMC at 400 cost
- Bet on AI power sector: IREN + VST
- Layout in commercial aerospace in advance: RDW + FLY
- The remaining 1,200€ went all into OUST, a leading US LiDAR company I’d never even heard of before. As someone working in robotics, I felt familiar with its uptrend and bought casually, only to get trapped at a high price.

## Reflections

1. The essence of stock investing is paying the smartest people in the world to work for you. We should pick the best and most promising companies to hold long-term, minimize over-research and frequent trading. Less short-term speculation, more long-term value holding.
   See my homepage
2. Build an “untouchable” core position (50% of capital).
   My anchor holdings: Tesla, NVIDIA, Micron, TSMC, Google. Buy top tech companies at reasonable valuations, hold firm, and profit from the dividend of global tech progress.
   See my homepage
3. Use the other 50% for trend speculation and short-term trades: semiconductors, optical modules, robotics, and the energy bottleneck brought by the AI boom.
   See my homepage
4. Even great companies deserve a good entry price. I was too impulsive with TSMC. For companies worth holding for a lifetime, wait for market pullbacks — US stocks always offer chances to dip buy — then accumulate heavily.

   Tomorrow’s plan: Choose one between OKLO and SMR in the nuclear energy sector, and start building positions in Microsoft.
   I will also sort out a tiered ranking of companies worthy of lifetime holding, including SK Hynix from South Korea, ByteDance from China, together with outstanding enterprises from the US and Europe, and make a comprehensive tier list.

The 10-year US Treasury yield is about 90 basis points higher than the S&P 500 earnings yield, marking the second-largest negative spread in 24 years.

Over the past five years, this spread has narrowed by 680 basis points.

This means taking on higher risk to buy stocks but receiving lower returns.

The market is no longer driven by a "risk premium," but rather by betting on future growth.

Historically, this situation has only occurred when sentiment is extremely high and valuations have been pushed to their limits.

📈 YTD: Approximately -25.6% (Restarting in 2026)

🤔 Today's Summary: SanDisk's earnings report gave everyone confidence. Storage might really be different this time, with reduced cyclical attributes, but it's currently rising wildly, showing no signs of weakness. I sold some of my storage holdings, and MU will also be affected by the call. Perfect timing, light positions over the weekend, can do whatever I want this weekend.

Today's US Stock Market Summary:

TSLA: $397

+4.06%

This recent rally has been quite strong, climbing steadily from its lows.

However, there's a problem: there's significant resistance around $400, and the short-term gains have been rather rapid. I'm currently debating whether to hold on or take some profits. Let's discuss this in the comments!
