description: "$Roundhill Memory ETF(DRAM.US) This stock should have already accounted for Samsung and SK Hynix yesterday. Samsung and SK Hynix rose during the day today, but yesterday it relied solely on Micron, which couldn't rise by more than six points. Today at 8 o'clock, when SK Hynix and Samsung opened, they surged again, so it also surged to two points. The weightings of Samsung, SK Hynix, and Micron in it are all roughly 25%-35%. If only Micron was accounted for yesterday, it couldn't have risen by more than six points."
