DRAM vs DRMP vs HBMX vs KMEM: Which Is the Better Pick in 2026?

Overview

All four funds chase the memory-semiconductor trade — DRAM, NAND, and high-bandwidth memory (HBM) makers plus their supply chain — that sits at the center of the AI infrastructure build-out. They split cleanly on two axes: cost and purpose. DRAM (Roundhill Memory ETF) is a passive, growth-oriented thematic fund with no distributions, the lowest cost tier, and by far the most scale. KMEM (Kurv Memory Select ETF) is a low-cost, focused pure-play on the memory producers themselves — SK hynix, Micron, and Samsung — that just launched. HBMX (Tuttle Capital Concentrated Memory Stack ETF) is an actively managed, concentrated appreciation play. DRMP (Tuttle Capital Memory Stack Income Blast ETF) is the outlier: an actively managed, non-diversified fund that layers put credit spreads on memory names to push out a 35.59% distribution paid weekly.

How they differ

The first divide is income versus growth. DRMP is the only fund built for current income, and it manufactures that yield with options rather than underlying dividends. DRAM pays nothing, KMEM has not established a distribution, and HBMX distributes only annually with no stated yield — the other three are appreciation vehicles.

The second divide is cost and scale. DRAM and KMEM charge 0.65%; both Tuttle funds (DRMP and HBMX) charge 0.95%. On assets the gap is enormous: DRAM holds roughly $17.5B, while DRMP is near $6.4M, HBMX does not disclose a figure, and KMEM launched on June 30, 2026 and has no reported AUM yet. Only DRAM has the scale that supports tight spreads and low closure risk.

The third divide is structure. DRAM is passive and diversified within its thematic mandate. HBMX and DRMP are actively managed and concentrated, and DRMP is explicitly non-diversified. KMEM takes a selective look-through approach but gains its exposure through a derivative overlay rather than simply holding the shares outright — a wrinkle that can introduce roll, basis, and counterparty considerations that a plain equity basket like DRAM does not carry.

Who each is best for

DRAM: Investors who want broad, liquid, low-cost exposure to the memory cycle and can tolerate growth volatility without needing income. It is the only fund here with institutional scale.

KMEM: Investors who want a focused, low-cost pure-play on the dominant memory manufacturers (SK hynix, Micron, Samsung) and are comfortable with a brand-new fund and a derivative-overlay structure in exchange for that concentration.

HBMX: Investors comfortable delegating active manager selection inside a narrow thematic band, seeking concentrated capital appreciation and accepting annual distribution timing.

DRMP: Income-focused investors with high risk tolerance who want to harvest options premium from a volatile sector and can live with weekly payout variability, potential NAV erosion, and non-diversified single-position risk.

Key risks to know

• Brand-new fund risk at KMEM: KMEM launched June 30, 2026, so it has no meaningful track record, no established AUM, and unproven trading liquidity. Its derivative-overlay structure means returns may diverge from a fund that simply holds the same stocks, and early-stage funds carry elevated closure risk if assets do not accumulate.

• Options-income sustainability at DRMP: A 35.59% distribution sourced from put credit spreads depends on sustained implied volatility and continued pullbacks. If volatility compresses or memory stocks grind higher without dips, the premium shrinks and payouts can drop sharply or come partly out of NAV.

• Concentration and cyclicality across all four: Memory is deeply cyclical. An AI-capex slowdown, a memory-pricing glut, or a shift in memory architecture would hit DRAM, KMEM, HBMX, and DRMP together — and at DRMP the long book and the short options can lose in tandem.

• Illiquidity and viability at DRMP, HBMX, and KMEM: DRMP near $6.4M, HBMX undisclosed, and KMEM not yet reporting AUM all face closure risk and potentially wide bid-ask spreads. Only DRAM's ~$17.5B base insulates it here.

• Non-diversified status at DRMP: Tuttle flags DRMP as non-diversified, meaning a single position or tight cluster can exceed 25% of net assets, amplifying single-name blow-up risk.

Bottom line

DRAM is the scale option: liquid, low-cost, passive memory exposure with no distribution drag. KMEM offers a similarly low-cost but far more focused pure-play on the memory manufacturers, with the caveats that it is brand-new and uses a derivative overlay. HBMX trades simplicity for active, concentrated appreciation at a higher fee, and DRMP trades everything for a high weekly options yield that carries the most structural risk — small AUM, non-diversified status, and payouts that depend on continued volatility. If you want broad, scalable memory exposure, DRAM stands out; if you want a cheap focused bet on the producers, KMEM is the newcomer to watch; if you are chasing weekly income from options on a narrow sector, DRMP is explicit about that trade-off. Past performance in AI semiconductors does not predict future returns.
