4. -- Apple (AAPL) - Get Report made it easier for long-time shareholders to nominate a director for its board, joining a growing list of companies offering "proxy access," The Wall Street Journal reported.

Apple, in a securities filing, said its board adopted amended bylaws that allow a shareholder, or a group of up to 20 shareholders, holding 3% of its shares continuously for three years to include board nominees in the company's annual proxy statement.

The bylaw allows shareholders to nominate up to 20% of Apple's directors. Apple's board currently has eight members, so shareholders could nominate one director, according to the Journal.

5. -- Nike (NKE) - Get Report reported fiscal second-quarter earnings of 90 cents a share, higher than a year earlier and ahead of Wall Street forecasts. But revenue of $7.69 billion came in below estimates.

The athletic apparel maker said worldwide future orders for Nike Brand athletic footwear and apparel to be delivered from December through April were 15%t above the same period a year earlier. Excluding currency, future orders would have increased 20%, the company said.

6. -- Alphabet's (GOOGL) - Get ReportGoogle is building a new mobile-messaging service that taps its artificial intelligence know-how and so-called chatbot technology to try to catch up with rivals such as Facebook in the fast-growing arena, the Journal reported, citing people familiar with the matter.

Google's two messaging services -- Hangouts and Messenger -- trail far behind Facebook's WhatsApp and Messenger and Tencent's WeChat, the most popular messaging app in China, the Journal noted.

For its new service, Google plans to integrate chatbots, software programs that answer questions inside a messaging app, the people familiar with the matter said. Users will be able to text friends or a chatbot, which will scour the Web and other sources for information to answer a question, the people told the Journal. It's unclear when Google will launch the service, or what it will be called.

7. -- Drugmaker Shire (SHPG) - Get Report made a new acquisition offer for Baxalta International (BXLT) that is roughly in line with Baxalta's valuation expectations, making a deal in the coming weeks likely, people familiar with the matter told Reuters.

An agreement would end Shire's five-month pursuit of Illinois-based Baxalta and create one of the world's leading specialists in rare diseases, according to Reuters.

Baxalta's board rejected an all-stock offer from Shire in August, saying it had significantly undervalued the company.

-- Chipmaker Micron Technology (MU) - Get Report posted fiscal first-quarter adjusted earnings of 24 cents a share, topping estimates by a penny.

Pandora (P) , which doesn't do direct deals with music owners so it can't do on demand deals, won't have access to the full Beatles catalog, Re/code reported. Pandora does have Beatles songs available via its Web radio service but with various restrictions.
