股价表现方面，英伟达周五上涨超3.9%%。过去六个月该股累计涨幅约为25%，仍落后于同期费城半导 体指数约35%的整体涨幅。 伯恩斯坦的上述观点发布之际，市场对人工智能投资周期的可持续性正出现更多讨论。一些投资者开始 质疑，高强度的AI算力资本开支是否能够带来与之匹配的回报，这也使得包括英伟达在内的AI核心标 的近期估值承压。 作为人工智能行情的核心受益者，英伟达目前的股价约为未来一年预期盈利的25倍。Rasgon表示，对这 家公司而言，25倍的前瞻市盈率意味着其估值仅处在过去10年区间的第11百分位，处于历史低位水平。 报告进一步指出，这一估值水平不仅在绝对意义上"相当便宜"，从历史经验看也具备较高的回报潜力。 Rasgon称，过去10年中，凡是在英伟达估值低于25倍时买入并持有一年的投资者，平均回报率超过 150%，且在统计样本中未出现一年期持有亏损的情况。伯恩斯坦目前给予英伟达"跑赢大盘"评级，目 标价为275美元。 伯恩斯坦最新研报指出，英伟达(NVDA.US)当前相对于费城半导体指数(SOX.US)的估值水平处于极具 吸引力的区间，无论从相对估值还是绝对估值来看，都为未来股价回报提供了有利基础。 伯 ...
