$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.
