Since that announcement, the equal-weighted Mag-7 index has underperformed the S&amp;P 500, but it's now within a whisker of catching up.</p><p>To contextualize: on Monday, January 27 - the day DeepSeek hit the headlines - <strong>Nvidia dropped -17%, recording the largest single-day market cap loss in history at $593 billion. </strong>Markets stabilized briefly before declining further into and just after “Liberation Day.” From DeepSeek Day to the post-Liberation Day trough, Nvidia fell roughly -34%. However, since then, <strong>it has staged an extraordinary rally of +87%, placing it +24% above the level it held immediately prior to the DeepSeek-triggered sell-off.</strong></p><p>Looking across the broader Mag-7 complex since, <strong>Tesla has been the clear laggard, </strong>weighed down by ongoing political tensions between Trump and Musk and broader investor concerns over earnings sustainability. By contrast, Microsoft and Meta — both reporting tonight — have outperformed the S&amp;P 500 since DeepSeek Day, alongside Nvidia.</p></div></div></div>
