Weak start for the first day of the last quarter.

The markets started the week in the red after economic numbers came in less than expected, showing a slight slowdown in real estate. The Dow 30 lost 54, the S&P 500 lost 7, and the Nasdaq 100 was off by 11. Tomorrow offers little in the way of scheduled news so traders will have to be on the lookout for unexpected announcements.

Deutsche Bank (NYSE: DB) shares were only open in the states today (-0.84%) and continue to be a major focus for investors. The stock was closed in Germany today due to a public holiday. Germany's largest lender continues to negotiate with US authorities to settle charges related to the sale of toxic mortgage securities before the financial crisis. The stock jumped 14% Friday following reports Deutsche Bank was close to settlement with the US Justice Department for $5.4 billion, which was way less than the $14 billion initially discussed. However, The Wall Street Journal reported that the details of deal remain in flux, with no agreement presented to senior decision makers on either side.

Tesla (NASDAQ: TSLA) shares are enjoyed a nice 4.74% gain today. News came out that the electric car maker set records for vehicle deliveries and production in the third quarter. Tesla delivered 24,500 cars in the last three months, after missing its targets in the previous two quarters. The company run by Elon Musk repeated its goal of delivering 50,000 vehicles in the second half of this year. Investors showed their trust in the CEO today with a nice pop in the stock.

Twitter (NASDAQ: TWTR) shares added another 4.12% today as takeover talk for the social media firm continues. Late Friday, Bloomberg reported that Google's parent company Alphabet is considering an offer to buy Twitter. Other potential suitors include, Disney (NYSE: DIS), Salesforce.com (NYSE: CRM), Microsoft (NASDAQ: MSFT) and AT&T (NYSE: T).
