description: "Later, focus more on the major market indices. Playing the indices may seem to yield less on the surface, but over a few years, it's actually quite stable and profitable.The reason is that popular stocks are places where retail investors cluster,and when retail investors cluster, they are easily targeted by institutions with waterfall sell-offs, making it hard to avoid.For example, Microsoft from 470 to 349. Most people probably couldn't hold on through that process and sold at a loss. It's highly likely to recover in the second half of the year, and then those who sold will just be left watching.For example, the flash crashes of Dell and IBM. Also inexplicable…For example, the memory sector, what's happening now, how many Korean families have lost everything in it.When something is popular, you're reluctant to leave, after all, you made a lot of money before, developed a fixed mindset, and coupled with the unwillingness to accept a small loss. But when the main players' scythes come down, it's just a few cuts, resulting in six months of wasted effort and possibly even a loss.Unless you're truly the kind of value investor who completely doesn't care about short-term price fluctuations… such people are still relatively few. Of course, looking back at the Magnificent Seven now, it's not so disheartening, right?"

  - **哈哈龙** (2026-07-15T15:36:35.000Z): Okay, thanks. The trend is very weird. On one hand, they're releasing positive news, and on the other hand, funds keep flowing in, yet it keeps falling...

- **三思又三思 · 2026-07-15T14:58:33.000Z · 👍 1**: The main force of NOK has been accumulating for several days, and there is relatively good positive news today, but the short position main force of this one is the most ruthless and outrageous I've ever seen.
  - **三思又三思** (2026-07-15T14:58:49.000Z): It's all smashed up
  - **钢铁纪律** (2026-07-15T15:00:02.000Z): Fortunately, not as ruthless as Alibaba. Alibaba plummeted from 180 to 88, what a joke.
  - **三思又三思** (2026-07-15T15:02:08.000Z): Hahaha, M7 is drained today. With that good news from NOK pre-market, I thought I could make over 12 bucks today.

- **X.X · 2026-07-15T14:55:32.000Z**: So, Iron Brother, what should we do with NOK? Keep pretending to be dead or cut the loss?
  - **钢铁纪律** (2026-07-15T14:57:15.000Z): I won't cut my losses. My cost basis is 12, which I think is okay. My Alibaba cost basis is 145, and even when it dropped to 88 at its worst, I was able to hold on and wait for it to break even. It's 
  - **X.X** (2026-07-15T15:01:12.000Z): My cost basis for the underlying stock was 14.5, and I didn't sell at 17. Now it seems I can only hold for the long term. I feel the entire hardware-related sector is undergoing valuation compression.

  - **BenChen** (2026-07-15T14:57:26.000Z): Do you believe I'm holding the underlying stock for the long term? 🥹🥹
  - **钢铁纪律** (2026-07-15T14:58:20.000Z): I don't believe it.
- **zeta · 2026-07-15T14:51:09.000Z**: I only dare to play with stocks like the Mag 7, combined with selling puts and calls, and I'm quite satisfied with the annual returns.
  - **Chenss** (2026-07-15T14:53:22.000Z): Don't need to sell Nasdaq?
  - **zeta** (2026-07-15T14:54:24.000Z): Not playing with indices for now. I'm still young and want to get my hands on the actual trading. I'll play with indices when I become an old-timer.
