Roundhill Memory ETF surges more than 70 per cent as Wall Street chases AI boom

The Roundhill Memory ETF (DRAM) has posted a remarkable rise of more than 70 per cent in just 24 trading sessions since its launch in early April. The fund has reached an intraday record on 14 occasions, drawing immediate comparisons from analysts to BlackRock's spot bitcoin ETF (IBIT) due to the speed of its market impact. With assets under management approaching $3.3 billion, the instrument has quickly become a primary vehicle for traders seeking direct exposure to the artificial intelligence memory boom.

Unlike broad semiconductor funds that offer diversified exposure across the industry, DRAM is specifically structured to target the memory supply chain. The fund's portfolio is heavily concentrated, with Micron, SK Hynix and Samsung accounting for nearly 70 per cent of holdings, while the top seven positions make up approximately 90 per cent of the fund. This structure provides US investors with access to foreign memory giants like SK Hynix and Samsung, which currently lack straightforward US-listed American depositary receipts (ADRs).

The rally in the ETF tracks the Bloomberg Global Memory Index, which has gained nearly 680 per cent since the start of 2025. This surge marks a significant departure from previous two-decade memory cycles, driven instead by surging demand for artificial intelligence hardware. Samsung has recently become the latest public company to reach a $1 trillion valuation, further highlighting the scale of the sector's re-rating.

For investors, the fund introduces specific considerations regarding currency fluctuations and trading-hour differences associated with foreign equities. While SK Hynix has filed for a US listing, the ETF currently offers a liquid alternative for accessing these stocks. The concentration inherent in the fund means it offers more direct memory exposure but also less room for error if the trade reverses compared to broader diversification options.

Technical analysis suggests that standard playbooks are not yet applicable to such a young fund. Traders are primarily watching the launch trend line as the key indicator, with a break below it potentially signalling a loss of momentum. As long as the fund continues to ride this ramp, it remains the dedicated basket for those betting on the dedicated memory component of the AI revolution.

The performance of DRAM underscores a shift in how Wall Street is approaching thematic equity trades. By wrapping the existing vertical rally in a concentrated ETF, Roundhill has created a new ticker that has already attracted significant attention from institutions and retail traders alike.
