Opnext Inc. (Nasdaq: OPXT) CEO Gilles Bouchard has resigned, the company announced this morning. Harry Bosco, chairman of the optical components company and Bouchard's predecessor, is returning to action as interim CEO. Opnext officials weren't immediately available for comment.

Why this matters
The rest of the optical sector has rallied while Opnext has lagged, and that could be what prompted the board to make a change. (These "resignations" are rarely voluntary.) In the past 12 months, Opnext shares are down 18 percent, while JDSU (Nasdaq: JDSU; Toronto: JDU) and Oclaro Inc. (Nasdaq: OCLR) are both up roughly 65 percent, and Leading Lights winner Finisar Corp. (Nasdaq: FNSR) is up 223 percent. (See LR Names 2010 Leading Lights Winners.)

Opnext shares are up 2 cents (1 percent) at $1.62 this morning.
