2. Apple shares soar on news of Berkshire Hathaway stake

Apple stock rose by 3.7 percent on Monday after billionaire investor Warren Buffett's Berkshire Hathaway revealed that it had bought a $1 billion stake in the iPhone maker.

4. Waze challenges Uber and Lyft with carpooling app

Google's Waze traffic navigation app announced Monday that it is testing a carpooling app in the latest challenge to Uber. In the test, the app — Waze Rider — will let more than 25,000 employees at select companies in the San Francisco Bay Area hitch rides with Waze drivers with similar commutes. Google purchased Waze for $1 billion in 2013, setting up a showdown against ride-sharing powerhouses Uber and Lyft, which have their own carpooling options allowing riders to cut their trip costs.
