Retail traders are all in on the memory trade.

The group's latest obsession as of late has been the Roundhill Memory ETF, a relatively new exchange-traded fund that tracks computer memory and storage stocks. Since it launched six weeks ago, individual investors have poured more than $250 million into the product on a net basis, according to data from Vanda Research, outpacing flows into longtime favorites like Nvidia.

What stands out about the buying is how quickly retail investors have piled into the stock, Vanda said earlier this week.

-- Cumulative net buying of the ETF, which trades under the ticker DRAM, crossed the $200 million mark in just 27 days. That's faster than other thematic ETFs that have been popular among the cohort.

-- It took 29 days for the iShares Bitcoin Trust ETF $(IBIT)$ to reach that mark after it launched in 2024, according to Vanda, despite the excitement at the time surrounding the launch of crypto ETFs.

-- The Direxion Daily TSLA Bull 2X Shares $(TSLL)$-which aims to deliver investors two times the daily performance of Tesla stock-took even longer, at 199 days.

Part of the speed may be a function of retail investors' larger presence in the U.S. stock market. But it also speaks to the current frenzy around the AI infrastructure trade.

DRAM's two biggest holdings are SK Hynix and Micron Technology, whose stocks have both doubled since the launch of the ETF on April 2.
