Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of September 18, 2026. YTD and 1Y are cumulative; windows of one year or longer are annualized. “Since Jun 2026” measures every fund from June 11, 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.

How the risk works

Read this before the income numbers below: the strategy mechanics on this page shape what those payouts can cost you.

  • Capped upside and premium dependence. DRMP generates income by selling options, which trades away part of a strong rally in exchange for premium. Distributions can include return of capital, and a payout the underlying assets cannot sustain shows up as NAV erosion over time — the big yield number is not free.

More comparisons to explore

DRAM vs DRMP vs HBMX — at a glance

Generated September 20, 2026.

The critical distinction is income generation via options strategy versus capital appreciation, combined with concentration and fund scale. This strategy exposes DRMP to gap risk and assignment at inopportune times, a structural tradeoff DRAM and HBMX do not carry.

Second, HBMX is concentrated by design—the prospectus explicitly targets focused exposure to DRAM, NAND, high-bandwidth memory, and the supply chain—while DRAM diversifies across memory companies broadly. HBMX's active management and concentration invite higher volatility around memory-cycle upturns and downturns, whereas DRAM's 0.65% passive structure with $25.9B in assets offers steadier exposure.

Who each is best for

  • DRAM: Fits investors seeking broad, low-cost memory semiconductor exposure with minimal trading friction and no income dependency. The large asset base and passive structure appeal to those comfortable with buy-and-hold capital appreciation in the memory sector.
  • DRMP: Fits investors with high current income needs who understand options mechanics and can tolerate assignment risk, gap risk, and potential NAV volatility in exchange for weekly payouts. Suits those actively monitoring positions and willing to roll or exit holdings as market conditions shift.
  • HBMX: Fits investors who believe concentrated exposure to memory producers and their equipment partners will outperform a broader memory index, and who prioritize long-term capital growth over current income. Designed for those comfortable with active management and higher portfolio concentration.

Key risks to know

  • NAV erosion and assignment risk on DRMP: The 31.77% put credit spread yield likely requires either consistent equity appreciation, reinvestment gains, or systematic capital erosion to sustain. Gap moves—sudden semiconductor industry disruptions or downturns—can force assignment at unfavorable prices, locking losses. Weekly distribution frequency masks underlying volatility.
  • Concentration and cycle risk on HBMX: A focused portfolio of memory producers and their supply chain is highly sensitive to memory-chip pricing cycles, fab capacity announcements, and AI infrastructure investment sentiment. Downturns in DRAM and NAND pricing can sharply compress valuations across all portfolio holdings simultaneously. Early-stage funds of this size often face tracking error, wider bid-ask spreads, and potential closure if inflows don't materialize, creating reinvestment or exit friction for shareholders.
  • Options and leverage embedded in DRMP: Put credit spreads embed leverage and directional risk through the short put position. While the strategy is transparent, unexpectedly sharp rallies or collapses in memory stocks can trigger assignment or margin pressure, and implied volatility swings change the effective payoff.
  • Memory sector concentration across all three: All three funds concentrate on one semiconductor subsector. Memory-chip prices are cyclical and driven by supply-demand imbalances; an industry-wide oversupply event or demand shock would hit all three simultaneously, offering no diversification across the comparison.

Bottom line

If you want broad, low-cost memory exposure and can forgo current income, DRAM's scale and passive structure offer simplicity. If you prioritize high current income and understand options assignment risk, DRMP's weekly distributions address that income need, though the sustainability question and small asset base warrant close monitoring. If you believe concentrated exposure to memory producers and their equipment partners will drive long-term capital gains, HBMX fits that thesis, but concentration and small scale introduce higher volatility and potential liquidity friction. All three share memory-sector cyclicality; past performance does not predict future results.
