<p>股市今年表現良好。<strong>納斯達克 100</strong> 科技指數上漲了 17%，而更為多元化的 <strong>標準普爾 500</strong> 指數上漲了 9%。但在四月初，Roundhill Investments 推出了一隻新的交易所交易基金（ETF），其漲幅已達到 121%。</p>
<p>這隻基金名為 <strong>Roundhill Memory ETF</strong>（DRAM +6.63%），顧名思義，它專門投資於設計、製造和分銷內存芯片及組件的半導體公司。目前，由於人工智能（AI）行業的巨大需求，全球內存短缺，這推動了幾乎所有頂級供應商的收入和盈利大幅增長。</p>
<p>但儘管內存行業顯然受益於有利的市場環境，這隻 ETF 並不是一個明確的買入選擇。投資者需要了解以下信息。</p>

<h2>三隻股票佔 Roundhill Memory ETF 近 75% 的份額</h2>
<p>AI 軟件應用需要大量計算能力，這通常由稱為圖形處理單元（GPU）的專用數據中心芯片提供。高帶寬內存（HBM）將數據存儲在準備狀態，以便 GPU 需要時使用，從而最大化處理速度。內存容量不足會導致瓶頸，迫使 GPU 在等待新信息時暫停。</p>
<p>對 HBM 的需求如此強勁，以至於許多供應商已削減其他類型內存的生產，以滿足其利潤豐厚的數據中心訂單。這導致全球各類內存短缺，並推高了智能手機和計算機等消費電子產品的價格。事實上，<strong>蘋果</strong> 最近宣佈計劃因內存成本飆升而提高部分設備的價格。</p>
<p>Roundhill Memory ETF 僅持有 20 只股票，但其前三大持倉佔投資組合價值的驚人 74.7%。</p>

<p>Roundhill Memory ETF（DRAM）於四月推出，受益於人工智能推動的高帶寬內存需求，漲幅達到 121%。其投資組合高度集中於美光科技、三星和 SK 海力士，這三家公司佔據了 74.7% 的持倉比例。儘管表現強勁，作者仍建議保持謹慎，指出潛在的長期風險，例如企業減少對人工智能的支出以及製造能力的增加可能導致供應過剩和價格崩潰</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. A low memory capacity would cause bottlenecks by forcing GPUs to pause while they await new information.</p>

</div><p>Demand for HBM is so strong that many suppliers have cut production of other types of memory to fulfill their lucrative data center orders.
