description: "$Roundhill Memory ETF(DRAM.US) I've already added to my position 3-4 times, with an average cost of 36.7, and I'm basically entering a stable observation period for my holdings. The memory sector is too strong; from what I've observed, it's basically been climbing step by step all the way up, relying on super-strong performance. Using 40 as the base point, I'll add on every 5% drop and move the base point up on every 10% rise. This minimizes the chance of missing out, and anchoring to round numbers doesn't work here. I'll operate this way until the end of June. Also, you must pair this with SanDisk when buying; this one's SanDisk content is too small."

- **Erstwhile · 2026-05-06T01:00:16.000Z**: I'm confused, it flew all the way from 42 to 49. I need to rethink how to evaluate the benchmark price.
- **fighting_74uKWk · 2026-05-05T01:10:02.000Z**: Boss, can you add me as a friend and give me some guidance? I'm still a newbie.
- **第一性原理 · 2026-05-04T12:25:35.000Z**: It's been skyrocketing every day. I originally wanted to wait for a pullback to buy, but now it seems I have to chase the rally to buy in?
- **冷罗和他的朋友们 · 2026-05-04T10:40:25.000Z**: Compared to SanDisk, MU is definitely better. His shareholding ratio is not a problem either.

  - **Erstwhile** (2026-05-04T09:10:01.000Z): I don't care how much it has risen in the past, but whether it will be better in the future. If so, is it worth my while to stay for it.
