description: "$Kurv Memory Select ETF(KMEM.US)$Roundhill Memory ETF(DRAM.US)Last night, I directly closed my DRAM position and swapped it for KMEM. Anyway, they both rise and fall together now. SK Hynix will be listed in a few days, so the one with a higher concentration is probably better. The downside is that the latter seems to have poor liquidity."

- **小波观澜 · 2026-07-06T14:02:45.000Z**: Why is the majority of the position in options?
  - **其实呢77** (2026-07-06T14:11:44.000Z): Damn, it really is. I don't understand why this unleveraged ETF would need to use options.
  - **其实呢77** (2026-07-06T14:18:33.000Z): I think it should be a display issue, at least the current rise and fall are fine. Leveraged ETFs generally shouldn't use options for balancing, only x2 ETFs use options for balancing.
- **东南西北的东Dong · 2026-07-06T13:48:15.000Z**: Another benefit is that it's newly listed and the price is low.
- **东南西北的东Dong · 2026-07-06T13:47:54.000Z**: No liquidity, indicating the market still doesn't recognize it.
