A red-hot ETF that launched just six weeks ago has surpassed Cathie Wood's flagship ARK Innovation $(ARKK)$ fund in assets.

Roundhill's Memory ETF, known by ticker DRAM, has accumulated some $9 billion in assets since its April 2 launch. The theme ETF tracks computer-memory and storage stocks, including companies like Samsung that don't trade in the U.S.

Individual investors have been piling into the fund at an unprecedented pace for a new launch, according to data provider Vanda Research.

The ARK fund, which invests in high-growth tech companies, was once the poster-child for active thematic funds, though it bled assets after performance started to suffer. It became hugely popular with individual investors in the early 2020s and inspired other managers to launch hundreds of thematic ETFs trying to replicate its success.

None have caught on quite like the DRAM ETF.
