It's a big earnings week, and so far stock markets are starting it off on the right foot. The Dow Jones Industrial Average (DJINDICES:^DJI) is up 0.27% as of 3:20 p.m. EST, and the S&P 500 (SNPINDEX:^GSPC) has gained 0.26%.

DuPont (NYSE:DD) and Travelers (NYSE:TRV) kicked of this week's earnings with relatively strong results. DuPont reported flat revenue of $7.3 billion and earnings of $0.12 per share, which was down 70% from a year ago. But after a terrible earnings report last quarter, the expectations for DuPont were low, and both results beat expectations. The stock has climbed 1.6% on the news.

Travelers has jumped 2.2% after reporting earnings per share of $0.72, crushing analyst estimates of $0.14. The company has been increasing premiums for customers across the board, citing volatile weather patterns as the reason. The company also booked a gain of $146 million on money previously set aside for claims from prior quarters.

Boeing (NYSE:BA) is one of the big losers on the market today, dropping 1.2% after the company suspended deliveries of its 787 Dreamliner. The FAA and other aviation regulators around the world have grounded the aircraft until the cause of two fires aboard Dreamliners can be discovered and resolved. This has become a big headache for Boeing and investors, and prospective investors should be cautious. But if shares continue to fall, the stock may be worth a closer look.

Earnings season continues at a fast pace over the next two days, with Google and Apple catching the eye of nearly every investor. Google reports after the close today and could give us an indication of where mobile and search trends are headed, while Apple will tell us how its quarter went tomorrow. Stay tuned for the response from Wall Street.
