1. Tesla to remain public: Shares in Tesla were poised to slump 5% on Monday after CEO Elon Musk said that he had given up on plans to take the electric-car company private.

There was heavy trading in Tesla (TSLA) stock ahead of the opening bell.

The billionaire entrepreneur stunned investors earlier this month when he tweeted that he had secured funding to remove the firm from the stock market.

Shares in Tesla jumped about 11% on August 7, the day Musk tweeted about his plan to take the company private. But the stock has tumbled 15% since then as doubts mounted and regulators reportedly looked into whether funding had been secured.

Musk said his change of heart came after talking to Tesla investors and realizing that taking the company private would be harder than he originally thought.
