shares popped following word from the company late Tuesday that it plans to "discuss its stronger business outlook" in a conference call after the close Wednesday.
The stock was recently up $3.55, or 9%, to $43.11.
Broadcom's announcement, which implies ahead of time that it will raise guidance, differs from the usual practice among most companies. Typically, firms either issue quarterly guidance without giving prior notice, or schedule a midquarter update without commenting ahead of time on whether the direction of their business is up or down.
A spokesperson for Broadcom said he couldn't comment on whether the company will be raising guidance. He also would not say whether or not Broadcom will confine its comments to the quarter now under way.
The conference call will be held on Wednesday, Feb. 18 at 4:45 p.m. EST time. Speakers will include Chief Executive Officer Alan "Lanny" Ross and Chief Financial Officer William Ruehle.
