Storage ETF DRAM Rebalances to Include GigaDevice with ~2.72% Weighting
Claire Weston
The fastest-growing ETF ever, DRAM, has added A-share-listed GigaDevice to its holdings at roughly 2.72% weight — the first time the fund's global memory map extends into mainland China.
Why does this ETF matter?
The DRAM ETF hit $20 billion in assets just 54 days after launch — the fastest ramp for any new ETF on record.
This means → massive passive capital is pouring into the memory sector, and every rebalance moves real money.
Its defining trait is concentration: the three memory giants — Samsung, SK Hynix, and Micron — account for roughly 75% of the portfolio. The rest covers the broader global memory supply chain.
What does adding GigaDevice signal?
The latest rebalance added two names: GigaDevice (兆易创新) from China's A-share market and Nanya Technology from Taiwan. GigaDevice's weight sits at about 2.72%.
This is the DRAM ETF's first-ever A-share holding. In plain terms = the fund's "world map of memory" had no mainland-China pin until now.
This reflects a widening in how global memory ETFs define the supply chain — moving beyond the top-three giants to include mainland-Chinese memory-linked companies.
What should investors watch next?
The ETF's future fund flows and rebalance moves will serve as a real-time window into how global passive capital allocates across the memory supply chain.
This means → if GigaDevice's weight rises in the next rebalance, it signals growing overseas confidence in China's memory segment; a cut would signal the opposite.
For A-share investors, the fact that a $20-billion offshore ETF now holds a stock on your watchlist is itself an incremental signal worth tracking.
