<div id="readability-page-1"><div> Shares of technology companies slid as traders continued to rotate out of the sector. A surge in Micron Technology shares after the session indicated the tech rally could soon resume, however. Shares of AI chip maker Cerebras Systems plunged despite reporting better-than-anticipated earnings Tuesday. Similarly, Micron, which is up more than sevenfold from a year ago, was down by more than 5% at one stage ahead of its earnings report. Micron shares rose by more than 15% in late trading as AI demand drove up prices of memory chips and the company's quarterly revenue. &#34;The problem is a lot of investors are buying things simply because they're up without understanding why they're buying it or what they're buying for that matter,&#34; said Oliver Pursche, senior vice president at financial advisory Wealthspire. South Korean chip maker SK Hynix plans to raise more than $29 billion for AI expansion through a U.S. listing, one of the largest ever share sales. OpenAI and Broadcom collaborated to develop a custom artificial-intelligence chip, marking the next step in the ChatGPT-parent's strategy to build out a full stack behind its models and products. <pre></pre> Write to Rob Curran at rob.curran@dowjones.com (END) Dow Jones Newswires June 24, 2026 18:49 ET (22:49 GMT)Copyright (c) 2026 Dow Jones &amp; Company, Inc.</div></div>
