What Happened?

Shares of electronic component provider Littelfuse (NASDAQ: LFUS) jumped 3.3% in the afternoon session after the company reported fourth-quarter results that beat analyst expectations and provided a strong forecast for the upcoming quarter, leading to an analyst upgrade. 

Littelfuse announced adjusted earnings of $2.69 per share on revenue of about $594 million, both of which were higher than anticipated.
