Here are five things you must know for Thursday, Aug. 2:   

1. -- Stocks Slide as U.S. Threatens Higher Tariffs on China

U.S. stock futures traded lower on Thursday, Aug. 2, and shares in Europe and Asia fell, sparked by a tougher stance on tariffs from the White House that rattled investors in China, where the Shanghai Composite Index dropped 2%. 

U.S. Trade Representative Robert Lighthizer said late Wednesday, Aug. 1, that the U.S. government would look to boost tariffs on $200 billion worth of China-made goods to 25% -from an initial proposal of 10% - as informal talks between Washington and Beijing failed failed to bridge the gap in what each consider to be a fair agreement on trade.

Contracts tied to the Dow Jones Industrial Average I:DJI   fell 166 points, futures for the S&P 500 I:GSPC  declined 17.25 points and Nasdaq I:IXIC futures were down 56.75 points.

U.S. stocks on Wednesday ended mixed after the Federal Reserve held interest rates steady but said the economy remains strong and inflation tame, laying the groundwork for additional rate hikes later this year.  

As for Thursday in the U.S., the economic calendar includes weekly Jobless Claims at 8:30 a.m. ET, and Factory Orders for June at 10 a.m.

2. -- Tesla Sees Profits Ahead 

Shares of Tesla Inc.  (TSLA) - Get Report   jumped 7.6% after the electric vehicle company reported a wider-than-expected second-quarter loss but CEO Elon Musk reiterated Tesla would it would turn a profit in the third quarter.

Tesla posted an adjusted loss of $3.06 a share, wider than Wall Street estimates that called for a loss of $2.92 a share. Revenue of $4 billion, however, topped forecasts of $3.92 billion.

The company also reported that it has a cash pile of $2.2 billion, which may alleviate investor concerns about the financial stability of the company. In its press release, Tesla set a goal of producing 6,000 vehicles a week by late August.

Tesla further noted that "a total vehicle output of 7,000 vehicles per week, or 350,000 per year, should enable Tesla to become sustainably profitable for the first time in our history - and we expect to grow our production rate further" in the third quarter.

While Tesla's earnings were far from clean, CEO Musk managed to do just enough to jump-start the bullish thesis on the stock that had all but died in recent months, according to TheStreet's Brian Sozzi.

Among other things, Musk promised (again) Tesla would be profitable each future quarter. He did leave himself an out should the economy weaken from strong second-quarter growth rates. The CEO also reiterated he doesn't expect an equity capital raise, and again suggested the company's fully autonomous driving capabilities were ready to go.
