Super Micro Computer stock was rising ahead of the opening bell, putting the server maker on course to build on Friday’s double-digit gains. Its shares, which trade under the ticker SMCI, have climbed 15% to $ $38.

Supermicro stock is surging today thanks to bullish coverage from an analyst. Lynx Equity recently published bullish coverage on the stock, and the firm thinks that new hardware from Nvidia will lift the server specialist's performance.

It's been a topsy-turvy year for Super Micro Computer ( SMCI 10.91%). Once seen as the next big artificial intelligence (AI) stock, it has come crashing down to reality in recent months due to concerns about the reliability of its numbers and accounting controls.

This was the stock's second consecutive day of gains.

In October, Ernst & Young resigned as Super Micro's auditor, resulting in a 33% stock plunge. An independent special board committee evaluated concerns from Ernst & Young and found no misconduct following a three-month investigation. The report recommended the company replace its CFO. The company said in November that BDO was its new auditor.
