DRAM Up 10.79% as Micron and SanDisk Post Blowout Memory Earnings

The Earnings That Moved the Basket

DRAM is a basket perp on the Roundhill Memory ETF, concentrated in Micron, Samsung, and SK Hynix, with SanDisk and a handful of supporting memory names filling in the rest. On May 5, the two biggest US-listed catalysts in that basket printed at the same time. Micron added 12% and SanDisk gained 10% on earnings that landed well above the tape.

Micron's fiscal Q1 2026 came in at non-GAAP EPS of $4.78 versus $3.94 consensus, on revenue of $13.64B, up 57% year-over-year. The Cloud Memory Business Unit alone did $5.28B at a 66% gross margin. The forward guide is heavier than the print: $18.7B revenue and $8.42 EPS for Q2. SanDisk's fiscal Q3 was the cleaner blowout — EPS of $23.41 against a $14.66 estimate, a 60% beat, revenue $5.95B (+251% YoY), and a datacenter segment up 645% YoY to $1.47B. Q4 guide is $7.75 to $8.25B at 79 to 81% gross margin. Both names are now sitting on order books that extend into 2027.

The Memory Cycle Behind the Print

None of this is a one-quarter story. Goldman Sachs raised its 2026 DRAM price forecast to 250 to 280% on April 23, up from a January estimate near 150%, and projects a 4.9% DRAM supply-demand gap in 2026 — the most severe shortage in fifteen years. The bank also walked back its prior view that the cycle would rebalance by 2027.

Micron CEO Sanjay Mehrotra echoed the setup on May 4, telling investors that AI memory demand could exceed 50% of industry TAM this year, that supply is "extremely tight and cannot be ramped up easily," and that the crunch is unlikely to ease before 2028. The macro is consistent with DRAM prices already up roughly 90% in Q1 2026 versus the prior quarter as the big three reallocate wafer capacity toward HBM for AI accelerators.

Why the Perp Reprices Faster Than the ETF

DRAM the perp expresses the same trade as the underlying equities, but with structural quirks worth knowing today. The basket is concentrated — Micron, Samsung, and SK Hynix drive most of the variance — so a single Micron or SanDisk gap moves the perp harder than a diversified sector index would. The HIP-3 contract carries a $25M open interest cap and a ±5% discovery bound, which means price can stick at the bound until the oracle catches up.

The more interesting feature is timing. Memory equities close on Friday at 8:00 PM ET; the perp keeps quoting through an internal weekend session that runs to Sunday 8:00 PM ET. That window is where divergence from oracle can be widest, and it is also when memory news from Asia — Samsung, SK Hynix, TrendForce — tends to break before US markets reopen. The print on May 5 is the kind of catalyst the perp was built to absorb in real time, but the same mechanics that make it sharp on the way up make it sharp on the way down.
