Key Highlights

  • T-REX 2X Inverse DRAM Daily Target ETF (CBOE:RAMZ) rose 13.05% to USD 22.52 on October 22, 2026, from USD 19.92, implying the Roundhill Memory ETF fell about 6.5%, simple arithmetic on the published change and the quote.
  • The fund targets twice the inverse of the daily return of the Roundhill Memory ETF, not of a single company, so it tracks a memory-stock basket. Holdings are total return swaps plus cash.
  • J.P. Morgan raised its fourth-quarter DRAM contract price forecast to a rise of 10% to 15% and NAND to 15% to 20%, which supports memory earnings.
  • The fund launched on July 28, 2026, charges 1.5% a year and held swaps worth more than 250% of net Assets on October 21, 2026, showing its leverage.

What Moved the Fund

The fund rose 13.05% in the October 22, 2026 session, implying the Roundhill Memory ETF fell about 6.5%, simple arithmetic ignoring fees. Memory stocks were hit by a broad selloff. Lam Research (NASDAQ:LRCX) posted record Revenue of USD 8.22 billion on October 21, 2026, then fell about 9% on October 22 after guiding December-quarter revenue to USD 8.6 billion, plus or minus USD 400 million, and citing Supply constraints. Sandisk, Micron and Advanced Micro Devices fell in premarket trading, and the semiconductor ETF fell about 4% to 5%. Memory shares had also reacted to China's ChangXin Memory announcing DRAM design progress on October 10 and 11, and profit-taking after large 2026 gains.

Memory Fundamentals

The underlying, the Roundhill Memory ETF (CBOE:DRAM), holds memory-related companies. Their Earnings depend on contract prices and AI demand. J.P. Morgan sees fourth-quarter DRAM contract prices up 10% to 15% and NAND up 15% to 20%, and TrendForce also expects NAND contract prices to rise 15% to 20%. SK hynix and Sandisk both report on October 29, 2026. SK hynix has a 50% share of HBM revenue, and Sandisk guided its next quarter to revenue of USD 10.3 billion to USD 10.8 billion. Risks include new Chinese supply, a slowdown in AI spending and the cyclical nature of memory, where prices can fall quickly. Samsung Electronics and Micron are the other major HBM suppliers.

Mechanics and Risks

RAMZ, issued under the T-REX brand, trades on Cboe BZX and charges 1.5%. Its holdings on October 21 were total return swaps referencing the Roundhill Memory ETF plus cash, and it is non-diversified. It resets daily, so if the underlying rose 10% then fell 10%, it would end down 1.0% while the fund would end down 4.0%, simple arithmetic. An underlying gain above 50% in a day would erase the fund. Because it is a fund on a fund, two layers of fees and tracking apply. Swap financing costs and a daily rebalance add friction beyond the stated fee, and counterparty risk applies. The fund is non-diversified and concentrated in one industry.

Where Things Stand

T-REX 2X Inverse DRAM Daily Target ETF (CBOE:RAMZ) rose because the Roundhill Memory ETF fell about 6.5% in an AI and semiconductor selloff, and the fund is built to return twice the inverse. Memory pricing remains supportive and two major reports are due on October 29, 2026, so the move may be short-lived. Gains in the underlying basket would hurt the fund within a day. Swap counterparties add risk.
