DRAM

This is the first ETF built entirely around memory chips, and it's been an absolute rollercoaster. Shares closed July at $50.37, down 3.8% that day, against a 52-week range of $26.14 to $81.34. So it has roughly doubled and then given back nearly 40% inside a year. The fund has gathered about $25.9 billion in assets, which is enormous for a niche thematic ETF and tells you how much appetite there's been for this trade. The expense ratio is 0.65% — not cheap, but in line with specialty funds. The idea behind it is straightforward and, we'd say, a good one: memory is the bottleneck of the AI buildout. As we covered in the memory shortage piece, the world's three big producers have shifted their factories toward the high-bandwidth memory that AI chips need, prices have gone vertical, and everything is sold out. This fund buys the companies on the winning side of that — SK Hynix, Micron, Sandisk, Western Digital, and similar names. Notably it's global, which matters here, because the largest memory producers are Korean and most US investors can't easily own them directly. That's a real reason a fund like this exists rather than just buying Micron. A few things we'd want you to know before buying it. It's extremely concentrated — the top ten holdings are about 88% of the fund, so you're not getting much diversification, you're getting a focused bet with a ticker. It's actively managed, meaning a person decides what goes in rather than tracking an index, and it uses swap agreements to get exposure to some foreign holdings, which adds a layer of complexity most index funds don't have. We also noticed at least one holding that isn't a memory company at all in the traditional sense, which is worth a look at the full list before you assume you know what you own. The bigger caution is the same one we raised with Lam Research: memory is the most brutally cyclical business in technology. When the cycle turns, it doesn't ease down — it collapses, and prices that rose 700% can fall just as fast. This fund gives you clean exposure to the best memory market in decades. It will also give you clean exposure to the end of it. (written with the help of Claude)
