Super Micro stock saw explosive gains following the dramatic upward guidance revisions, and bullish sentiment has carried over to this week's trading. In addition to that catalyst, the sales and earnings beats that ASML delivered with its Q4 report also helped send the server specialist's share price higher.

ASML is the leading manufacturer of advanced lithography machines used in semiconductor fabrication, and its performance is often viewed as a bellwether for the broader chip industry. The semiconductor equipment specialist posted net income of 2 billion euros on revenue of 7.2 billion euros, beating Wall Street's target for a profit of 1.87 billion euros on sales of 6.9 billion euros.

While ASML guided for its 2024 revenue to be roughly in line with the 27.56 billion euros it recorded last year, the company is seeing some AI-related demand tailwinds. Investors are viewing that as a positive indicator for Super Micro Computer, which has been benefiting from surging demand for artificial intelligence (AI) services.
