英伟达

<p>美国股市连续四天上涨，英伟达和博通引领了由人工智能驱动的涨幅。标准普尔 500 指数上涨 0.6%，接近历史最高点，而纳斯达克和罗素 2000 指数大幅上涨。强劲的财报和分析师的评级上调增强了对人工智能支出的乐观情绪。美国经济在第三季度增长 4.3%，支持美联储的稳健政策，提升了成长股的估值</p>

<div class="lb-trans"><h2>美国股市延续反弹：涨幅是广泛还是集中？</h2>
</div><p>Here’s what matters: Nvidia and Broadcom didn’t hog all the gains. Yes, they’re the stars. Nvidia has climbed 4.35% over the past five trading sessions, while Broadcom bounced higher after UBS lifted its price target and boosted AI revenue forecasts.</p>
