Total returns

100% reinvested · ex-date convention. Period returns use this fixed assumption, independent of chart settings. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year.

DRAM has outpaced HBMX over the year to date, posting a 33.32% total return against -41.43%. Figures are total returns: price change plus every distribution reinvested.

Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of November 5, 2026. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year. “Since Jun 2026” measures every fund from June 2, 2026 — the start of shared available history — so all funds share one comparison window. Volatility is the annualized standard deviation of daily total returns over the shared window since Jun 2026. Sharpe and Sortino divide the annualized return in excess of the risk-free rate by, respectively, that volatility and the downside deviation (both over the shared window since Jun 2026) — higher is better. Max drawdown is the largest peak-to-trough total-return decline over the same window — shallower is better.

Not a distribution payer

Projections assume the current yield and share price remain constant. Actual results will vary.

Bottom lineWe won't call this one: HBMX launched June 2026, so there is not yet a track record to compare. Compare the strategy, cost and holdings in the sections above and treat any performance figures for the newer ETF as provisional. What is already clear from the numbers above: the two do not cost the same — DRAM charges 0.65% against 0.95% for HBMX, and on funds tracking the same thing that gap compounds every year you hold.

Frequently asked questions

What is the difference between HBMX and DRAM?

HBMX (Tuttle Capital Concentrated Memory Stack ETF) concentrates the memory stack, including packaging and equipment. DRAM (Roundhill Memory ETF) holds memory companies. Cost is 0.65% versus 0.95%. Distributions are — and — as of November 2026. Universe, not a one-date yield, is the split.

Which of DRAM or HBMX pays more dividend income?

Neither DRAM nor HBMX currently reports a distribution yield, so neither is an income fund today. Compare them on holdings, cost, and total return instead.

What is the difference between DRAM and HBMX?

DRAM (Roundhill Memory ETF) is an ETF built around a thematic strategy, while HBMX (Tuttle Capital Concentrated Memory Stack ETF) is an actively managed ETF built around a thematic strategy. They are issued by Roundhill Investments and Tuttle Capital Management respectively.

Can I hold both DRAM and HBMX?

Yes. Their disclosed top-10 holdings share only 1 position, so combining both adds mostly distinct underlying names — see the holdings-overlap section above. Overlap outside the disclosed top 10 can still exist.

Which has lower fees, DRAM or HBMX?

DRAM has an expense ratio of 0.65% while HBMX charges 0.95%. Lower fees mean more of your investment returns stay in your pocket over time.

How much income does $10,000 in DRAM vs HBMX generate?

At current distribution rates, DRAM does not pay distributions, so there is no cash income to estimate. HBMX has not established a distribution history yet, so a cash estimate is not available.

Which has performed better historically, DRAM or HBMX?

DRAM has outpaced HBMX over the year to date, posting a 33.32% total return against -41.43%. Figures are total returns: price change plus every distribution reinvested. Past performance does not guarantee future results.

DRAM vs HBMX — at a glance

Generated October 31, 2026.

Figures quoted in this analysis are from its generation date and may lag the live snapshot table above, which always shows the latest data.

Overview

DRAM and HBMX are both thematic equity ETFs targeting the memory semiconductor ecosystem that powers AI infrastructure. DRAM uses a passive, broad-based approach with at least 80% exposure to memory companies and derivatives, while HBMX is actively managed and concentrates on a narrower set of holdings across DRAM, NAND, high-bandwidth memory producers, and their adjacent supply chain (advanced packaging, testing, equipment). The key distinction is breadth versus concentration: DRAM casts a wider net at lower cost, while HBMX applies active stock selection and tighter focus on what its managers view as the core memory ecosystem.

How they differ

HBMX's active management and concentrated portfolio strategy stands as the primary structural difference. DRAM holds at least 80% of net assets in memory company equities and derivatives, following a systematic rule; HBMX selects from a smaller universe of issuers across the memory supply chain, including equipment and testing companies.

On fees, DRAM charges 0.65%, while HBMX charges 0.95%, a 30-basis-point gap. DRAM's vastly larger asset base of $14.4B versus $19.4M reflects meaningfully different investor adoption and market presence. DRAM's beta of 4.1626 shows substantially higher sensitivity to broad stock market swings than typical equity funds, reflecting the concentrated cyclicality of memory semiconductors. Both distribute annually or less frequently, so neither is geared toward regular income.

Who each is best for

DRAM: Fits investors seeking straightforward, rules-based exposure to the memory semiconductor trade without active manager oversight, and who can tolerate the high market sensitivity that comes with a thematic single-sector play.

HBMX: Fits investors drawn to active managers' ability to identify differentiated opportunities within the memory ecosystem and who are comfortable with a smaller fund's research-driven positioning and potential for more tactical allocation shifts. A concentrated thematic bet on memory semiconductors amplifies broad equity volatility significantly.

  • Concentration and cyclicality. Both funds are tethered to the memory chip cycle, which is capital-intensive, highly competitive, and driven by commodity pricing, customer concentration, and geopolitical supply chain shifts. A cyclical downturn or oversupply in DRAM, NAND, or HBM would compress earnings and multiples industry-wide.
  • Active management risk in a smaller fund. HBMX's $19.4M in AUM creates exposure to manager stock-picking decisions across a concentrated portfolio. Concentrated positioning amplifies both the upside of correct calls and the downside of missteps.
  • Derivative and swap exposure. DRAM explicitly uses swaps and forward contracts to gain memory company exposure. These derivatives carry counterparty credit risk and reset or rebalancing costs that can drag on returns, particularly in fast-moving or stressed markets.

Bottom line

If you value simplicity and lower fees in a thematic memory play, DRAM's passive approach and 0.65% expense ratio offer broad sector access at lower cost. If you believe concentrated active selection can outperform within memory semiconductors, HBMX's focused thesis and manager discretion present a different profile—though the fund's smaller size and the active bet's track record merit scrutiny. Both carry material single-sector and market-sensitivity risk; past performance does not guarantee future results.
