Verizon shares rose slightly in premarket trading on Monday. 2. -- Tesla Motors ( TSLA ) and SolarCity ( SCTY ) have made progress in putting together a deal that will merge the electric car maker and the solar panel installer, people familiar with the matter told Reuters. The two companies, of which billionaire Elon Musk is a significant stakeholder, are in the final stages of carrying out due diligence on each other, and could agree on the terms of a deal in the coming days, Reuters reported, though it's still possible that their negotiations end unsuccessfully, the people said on Saturday. Musk is pushing for Tesla to acquire SolarCity and envisions combining SolarCity's panels with Tesla's in-house battery packs to "create stunning solar roofs with seamlessly integrated battery storage," while bringing to market not just electric cars but electric commercial trucks and buses.
