    Memory ETF Surges 121% with 75% Concentration in Three Stocks

    Question

    Memory ETF Surges 121% with 75% Concentration in Three Stocks

    Direct answer

    The DRAM ETF's extreme concentration makes it a pure-play bet on the memory cycle. While it has outperformed broader tech indices, the lack of diversification means any negative news from Samsung or Micron will have a disproportionate impact on the fund.
