Non-U.S.-listed constituents and swap-normalized CUSIP entries that fall outside our covered ticker universe are labeled "Not tracked" rather than linked.
Manager-driven rebalancing only. Creation-unit activity — authorized-participant creations and redemptions, which scale every holding by the same factor without reflecting a portfolio decision — is excluded by construction; see methodology.
No manager-driven trades recorded yet. Roundhill's daily holdings feed began publishing on 2026-08-31; trade detection compares two consecutive daily snapshots, so the first comparison — and the first rows here — will land after the next business day's file arrives.
Not disclosed in quarterly institutional filings — read directly from the fund's daily fund-facts file.
Only one daily snapshot is on file so far. A day-over-day trend will build as subsequent daily files are ingested.
Roundhill DRAM ETF (DRAM) is an actively managed exchange-traded fund from Roundhill Investments. Roundhill's fund FAQ confirms the fund is actively managed, with an investment committee responsible for security selection rather than tracking an index. As of the fund's most recent disclosures, net assets are approximately $25.59 billion across 25 holdings, with a 0.65% expense ratio.
The fund concentrates on the memory-semiconductor supply chain, and its largest positions are led by Korean and Taiwanese manufacturers. Because DRAM is an ETF rather than a 13F filer, the holdings and rebalancing data on this page are drawn from the fund's daily holdings disclosure rather than a quarterly 13F filing — the numbers update daily and are not subject to the 13F reporting lag.
