<p>股市今年表现良好。<strong>纳斯达克 100</strong> 科技指数上涨了 17%，而更为多元化的 <strong>标准普尔 500</strong> 指数上涨了 9%。但在四月初，Roundhill Investments 推出了一只新的交易所交易基金（ETF），其涨幅已达到 121%。</p>
<p>这只基金名为 <strong>Roundhill Memory ETF</strong>（DRAM +6.63%），顾名思义，它专门投资于设计、制造和分销内存芯片及组件的半导体公司。目前，由于人工智能（AI）行业的巨大需求，全球内存短缺，这推动了几乎所有顶级供应商的收入和盈利大幅增长。</p>
<p>但尽管内存行业显然受益于有利的市场环境，这只 ETF 并不是一个明确的买入选择。投资者需要了解以下信息。</p>

<h2>三只股票占 Roundhill Memory ETF 近 75% 的份额</h2>
<p>AI 软件应用需要大量计算能力，这通常由称为图形处理单元（GPU）的专用数据中心芯片提供。高带宽内存（HBM）将数据存储在准备状态，以便 GPU 需要时使用，从而最大化处理速度。内存容量不足会导致瓶颈，迫使 GPU 在等待新信息时暂停。</p>
<p>对 HBM 的需求如此强劲，以至于许多供应商已削减其他类型内存的生产，以满足其利润丰厚的数据中心订单。这导致全球各类内存短缺，并推高了智能手机和计算机等消费电子产品的价格。事实上，<strong>苹果</strong> 最近宣布计划因内存成本飙升而提高部分设备的价格。</p>
<p>Roundhill Memory ETF 仅持有 20 只股票，但其前三大持仓占投资组合价值的惊人 74.7%。</p>

<p>Roundhill Memory ETF（DRAM）于四月推出，受益于人工智能推动的高带宽内存需求，涨幅达到 121%。其投资组合高度集中于美光科技、三星和 SK 海力士，这三家公司占据了 74.7% 的持仓比例。尽管表现强劲，作者仍建议保持谨慎，指出潜在的长期风险，例如企业减少对人工智能的支出以及制造能力的增加可能导致供应过剩和价格崩溃</p>

<p>The stock market is having a good year. The <strong>Nasdaq-100</strong> technology index is up 17%, while the more diversified <strong>S&amp;P 500</strong> has gained 9%. But at the start of April, Roundhill Investments launched a new exchange-traded fund (ETF) that has already risen 121%.</p>

</div><p>AI software applications require substantial computing power, which is typically delivered by specialized data center chips called graphics processing units ( GPUs). High-bandwidth memory (HBM) stores data in a ready state for when GPUs need it, thereby maximizing processing speeds.
