This week’s market story was simple: oil took control, the Fed lost flexibility and stocks were left trying to decide whether this is actually a contained shock or the start of a bigger macro problem. For now, everything hinges on whether this is a spike or the start of a trend.

NVDA results really didn't matter. But the commentary from its conference call did. It revived some key AI bottleneck trades: memory and neocloud. We breakdown the takeaways and highlight the initial action in our latest Market Memo (8/27/2026): https://t.co/JJFWdNpHRr

[Roundhill Investments @roundhill]

An uncomfortable truth: NVDA results don't matter. Same goes for most of the NASDAQ 100 names given high fundamental expectations. It's about the future because of what's already priced in for growth.

Despite record construction, there is virtually no data center capacity left. Vacancy rates across primary U.S. markets fell from 5.8% in 2023 to 1.3% today. Demand is winning and neoclouds are built to capture the shortfall.

When we launched the Roundhill Memory ETF $DRAM, we believed memory was becoming the bottleneck of the AI buildout. Investors agreed faster than we ever could have imagined, and DRAM has become one of the defining launches in our firm's history.

One firm's capex is another firm's revenue. The Magnificent Seven write the checks. The memory makers cash them. For a month, being right on one meant being wrong on the other. That trend is ending. When both ends of the AI barbell get rewarded at the same time, we believe that is the market's green light. $MAGS $DRAM

[Roundhill Investments @roundhill]

Data center optical transceiver revenue reached roughly $17 billion in 2025. Nomura estimates it will grow to $48 billion in 2026, $97 billion in 2027, and $144 billion in 2028 (more than an 8x in three years).

The Roundhill Photonics & Optics ETF $LYTE is built to capture that ramp.
