description: "$Roundhill Memory ETF(DRAM.US) A pure-blood memory ETF is listed? Finally, there's an alternative to the South China 2x Long Samsung and SK Hynix ETFs. This can be considered a full-blooded memory ETF, and should be stronger than the current South China 2x ETFs which have too high volatility and decay. Marking this down. If memory stocks take another big dip, it's time to enter the market. 🏃‍♀️$XL2CSOPSMSN(07747.HK)$XL2CSOPHYNIX(07709.HK)"
