2. -- Tesla Slumps After Saying It Won't Be Going Private

Tesla Inc.  (TSLA)  shares fell 3.4% in premarket trading on Monday after the electric vehicle company led by CEO Elon Musk said Friday it wouldn't be going private.

"Over the past several weeks, we put in place a process led by a Special Committee of the Board to evaluate a proposal Elon was considering to take Tesla private. Yesterday, we held a Board meeting, during which Elon reported on the work he and his advisors have been doing in connection with this effort," said a post on the company's website. "Elon communicated to the Board that after having done this work and considered all factors, he believes the better path is to no longer pursue a transaction for taking Tesla private. After discussing this, we dissolved the Special Committee. The Board and the entire company remain focused on ensuring Tesla's operational success, and we fully support Elon as he continues to lead the company moving forward."

Musk wrote: "I knew the process of going private would be challenging, but it's clear that it would be even more time-consuming and distracting than initially anticipated. This is a problem because we absolutely must stay focused on ramping Model 3 and becoming profitable."

Musk sent Twitter ablaze on Aug. 7 by tweeting that funding for a deal to take Tesla private at $420 had been secured. Tesla closed Friday at $322.82.

3. -- U.S. and Mexico Close In on NAFTA Deal

The U.S. and Mexico were poised to reach a NAFTA deal - perhaps as soon as Monday - after five weeks of talks. The deal would create an opening for Canada to rejoin the discussions. 

Significant breakthroughs between Mexico and the U.S. came during the past several days on automobiles and energy, Bloomberg reported, citing three people familiar with the process. 

The two countries have been going back and forth because Donald Trump had threatened to withdraw from the 24-year-old trade pact unless it was reworked. Canada had stepped out of the negotiations, reportedly until Mexico and the U.S. agreed on new auto-trade rules.

The North American Free Trade Agreement went into effect under President Clinton in 1994. The agreement between the U.S., Canada and Mexico was initially created to help lower costs of trade and bolster North American trade.

5. -- China's Didi Chuxing Suspends Carpooling Service

Didi Chuxing, the Chinese ride-hailing giant, fired two executives and will suspend one of its carpooling services nationwide starting Monday after a woman was raped and killed allegedly by a driver in eastern China, the company said Sunday.

The moves come as the country's largest online ride-hailing platform scrambles to address public complaints that it isn't doing enough to ensure the safety of its users who it said book 30 million rides daily, the Associated Press reported.
