# Weekly Recap | Tema Memory ETF -5.21%, lower volume against market

## The Week

DISK.US fell 5.21% this week to close at $35.99, while the S&P 500 gained 0.49%, leaving the ETF trailing the benchmark by roughly 5.7 percentage points. The weekly range was 8.35%, with a clear rally-and-fade pattern: Monday opened weak near $35.01 before settling at $35.80, Tuesday and Wednesday crept higher, Thursday spiked to $38.03 then pulled back, and Friday slid back to $35.99. Weekly volume totalled 0.94 million shares, with daily turnover averaging about 188,000 shares, more than 40% below its median level, pointing to thin trading conditions.

## Sector News

Memory-related headlines dominated this week. Nvidia’s latest guidance re-ignited focus on AI computing demand, with several research notes flagging tightening memory supply and Micron announcing a step-up in capex to address AI memory shortages. Meanwhile, SanDisk, Western Digital and Seagate saw active trading, with some insider selling. As a Tema Memory ETF, DISK.US sits squarely in the storage and memory theme, where performance was mixed across names; the Philadelphia Semiconductor Index fell 2.02% on Friday.

## The Week Ahead

Macro data comes thick and fast next week: Dallas Fed manufacturing activity on Monday, S&P Global and ISM manufacturing PMIs plus JOLTS job openings on Tuesday, followed by ADP private payrolls and factory orders on Wednesday. If manufacturing and labour data stay firm, rate sensitivity could climb further, adding volatility to higher-multiple tech and memory names, and potentially feeding into DISK.US swings.

## In Short

DISK.US moved against the broader market this week, with notably lighter volume. The AI-demand and memory-shortage narrative remains intact at the sector level, but insider selling near highs and Friday’s chip weakness suggest sentiment flickering between conviction and caution. The next test is next week’s manufacturing and jobs data: stronger prints could keep thematic ETFs under pressure, while a stabilising tone may let the growth narrative regain the upper hand.
