description: "$Roundhill Memory ETF(DRAM.US) I really don't understand which stock this price movement is following? SK Hynix and Samsung should have risen by over 4%~5% today, right? Micron has also risen by 2%, so this being less than them is just too exaggerated?"

- **Sss · 2026-07-23T11:37:49.000Z**: Isn't this more stable than individual stocks? It hasn't fallen as much.
  - **小哈同学** (2026-07-23T12:27:43.000Z): It fell exactly as expected.
- **钝感资本 · 2026-07-23T10:14:27.000Z**: The decline is also small, and it's hard to tell in the pre-market now.
  - **小哈同学** (2026-07-23T14:09:19.000Z): How is it now? It dropped really hard.
  - **小哈同学** (2026-07-23T14:09:47.000Z): The current Hynix and Micron are really solid.
  - **钝感资本** (2026-07-23T14:12:48.000Z): Switch to Micron
