&lt;p&gt;If you only watch Nvidia, you are missing the most interesting story in semiconductors right now.&lt;/p&gt;
&lt;p&gt;In Q1 2026, SK Hynix posted an operating margin of 72%. That number is not a typo. It exceeded both Nvidia and TSMC in the same quarter.

Industry veterans say profitability like this has not been seen since Microsoft launched Windows 95 in 1995.&lt;/p&gt;</description></item></channel></rss>
