description: "1 SK HynixFriday's closing price was 2.425 million, next week's 2.517 million won is the key level; it needs to break through and hold above it to continue rising.If it fails to break through 2.517 million next week, I will reduce my position. If it breaks through, I will continue holding.2 Micron It will rebound on Monday night's session. The support range here is 850-940. As long as it doesn't fall below this range, the rebound will continue, but there is resistance around 1100.3 SNDKThe resistance range for the rebound is 1900,and the support range is 1650.Due to positive news, the rebound will start on Monday. I plan to hold if SNDK successfully breaks through 1900. If it can't break through 1900, I will reduce my position at that level, and add back that portion when it pulls back to around 1650 (if it does).Since the memory sector is no longer in a one-way rally, many bros are feeling a bit uneasy. I never used to look at charts, just held mindlessly. I spent some time researching over the weekend, for your reference. If you don't like it, don't flame, just ignore it."

  - **钢铁纪律** (2026-07-05T12:37:33.000Z): I've been trading stocks for many years and have a little bit of ability to read charts. Of course, most of the time I look at the fundamentals.

  - **钢铁纪律** (2026-07-05T12:51:17.000Z): I don't look at MAs, I count wave patterns.
- **不断学习，不断进步。 · 2026-07-05T02:08:44.000Z**: Boss, do you have any research on optical modules? The first two days of July, optical modules also dropped a lot. Will the AI hardware supply chain not rise like it did in the first half of the year anymore?
  - **钢铁纪律** (2026-07-05T03:08:45.000Z): After rising too much, it's time for an adjustment

- **深蹲达人 · 2026-07-04T08:05:29.000Z · 👍 5**: Brother Steel, in my humble opinion, we can actually refer to SK Hynix and Kioxia to anchor the correction range of Micron and SanDisk, as they are all strongly correlated. Kioxia and SanDisk have always had the strongest elasticity in the storage sector this year. If the support level cannot be hel
  - **大司马桓温** (2026-07-04T08:08:36.000Z): SanDisk has already corrected 28% from its high.
  - **深蹲达人** (2026-07-04T08:09:46.000Z): Hmm, 0.7 and 0.62 are both good points to add to your position. If you're bullish, add in batches.

- **路飞同学 · 2026-07-04T07:43:03.000Z · 👍 3**: Micron is back to 1000 over there now, sndk is around 1800, it's estimated to open higher on Monday anyway, ultimately a bunch of people are going to be washed out, and the semiconductor index has also gone up to 600.
