DRAM Bounces 7% as the Memory Washout Proves to Be Positioning, Not Demand

The Selloff Was Macro, Not a Demand Break

The Roundhill Memory ETF is a basket where Micron, SK Hynix, and Samsung make up more than 73% of holdings, so it trades as a proxy for the big three DRAM makers. Over the prior two weeks that basket got dragged into a bear market, down more than 20% from June highs, with the broader semiconductor complex shedding roughly $1.5 trillion in market value since June 25.

But look at what actually caused it. The Bank of Korea delivered a surprise 25bp rate hike — its first in about three and a half years — that tripped a KOSPI circuit breaker and sent SK Hynix's Seoul-listed shares down more than 7%. On top of that, reports of Chinese memory maker CXMT preparing an $8.55 billion IPO stoked supply-glut fears, CoreWeave was said to be hedging against a drop in memory costs, and Morgan Stanley told clients to sell chips and buy cloud. That is a positioning and macro washout, not evidence that anyone stopped buying memory.

TSMC Reset the Tape

The turn came one rung up the supply chain. TSMC posted a record Q2 — $40.2 billion in revenue, up 36% year over year, with net profit up 77.4% and gross margin at 67.7% — and lifted its full-year 2026 growth outlook to slightly above 40%, up from prior guidance of over 30%, while calling AI demand "extremely strong."

It also raised capex to $60–64 billion and announced a $100 billion Arizona expansion. For memory holders, the signal that mattered was capex direction: the entire bear thesis rested on AI hardware spending peaking in 2026, and TSMC's guidance and spending plans gutted it. That is what flipped the tape and let an oversold group start repricing.

The Fundamentals Never Broke

Underneath the tape, the memory supply story is intact. Q3 DRAM contract prices are still guided up 13–18% quarter-over-quarter with NAND up 10–15%, as suppliers keep redirecting wafer capacity toward HBM and leave conventional DRAM tight into 2027. Pricing power, not a glut, is the base case.

The single names led the bounce. SK Hynix jumped about 8% as HSBC reaffirmed it a top chip-sector pick, with bargain-hunting joined by short-covering and options-driven gamma buying that accelerated the move off session lows. The DRAM ETF itself has more than doubled since its April 2 debut, so even after this bounce it is well off both its peak and, at $52.45, still more than 20% under June highs. This is mean reversion off an oversold washout — the bull case reasserting, not a new high being made.
