Shares of Littelfuse ( LFUS) were among the Nasdaq's winners Friday, jumping 17% after the fuse maker lifted its first-quarter earnings and sales guidance. The company now expects earnings of at least 40 cents a share, up from an earlier view of at least 30 cents a share. The projection excludes about 3 cents a share in stock-based compensation costs. The company now sees sequential sales growth of at least 10%, up from an earlier view of 5% to 10% growth. Analysts polled by Thomson First Call expect earnings of 29 cents a share on sales of $125 million, or sales growth of 8%. "Our electronics business, which began improving late in the fourth quarter of 2005, has ramped-up faster than expected," Littelfuse said. "Improvement in telecom has been the most significant contributor, but all major end markets are showing positive trends, with particular strength in North American distribution." Shares were up $4.39 to $30.98. Superior Industries ( SUP) rose 6% after the wheel maker reported better-than-expected fourth-quarter earnings.

Shares of Terex ( TEX) fell 8% after the construction-equipment company said that it won't file its 2005 annual report on time and updated its guidance. Terex said that it is about four to six weeks behind schedule on its 2005 financial statements. "While the company is working hard to shorten the timeframe needed to complete its 2005 audited financial statements and submit its quarterly and annual filings for 2005, Terex will file a form 12b-25 notification of late filing with the Securities and Exchange Commission indicating that more time is required beyond the March 16 deadline to complete its 2005 annual report on form 10-K," the company said in a statement.
