In the last year, Broadcom stock has risen more than 80%, powered by strong demand for its chips, which are key components in common consumer products and functions including smartphones, wireless computer networks, movie and music streaming and cloud computing.
Avago, based in Singapore and San Jose, said it would hold a news conference Thursday but did not disclose the nature of it. Avago designs and develops hardware for both digital and analog components and hardware for cellphones, data networking, storage and telecommunications equipment.
Avago shares jumped $10.19, or 7.8% on Wednesday, to $141.49.

Nicholas III, Broadcom is one of the world's largest so-called fabless semiconductor companies, designing and developing products in laboratories and design centers for manufacture by independent chip makers around the world. The company has more than 10,000 employees worldwide, most of them engineers.
