Super Micro Computer ( NASDAQ:SMCI ) is trying to stage a comeback after taking a beating. It has bounced back nearly 4% today, after dropping over 8% on Monday and sinking 22% in the past week. The sell-off kicked into high gear after reports surfaced that Super Micro might raise cash through stock and bond sales, stoking fears of shareholder dilution. Add to that the lingering cloud of delayed financial filings and the sudden exit of auditor Ernst & Youngand investors are understandably nervous. But there's a silver lining: Super Micro secured a Nasdaq extension until February 25 to clean up its books, and a fresh audit from BDO gave the all-clear on fraud concerns.
