ROUGH ROAD

Tesla's latest quarterly results should provide more details into the company's rocky start to the year.

The electric car maker disclosed earlier this month that it churned out 77,100 vehicles from January to March, well behind the pace it must sustain to fulfill CEO Elon Musk's pledge to manufacture 500,000 cars annually. Tesla serves up its first quarter results Wednesday.

ON A ROLL

Wall Street expects another strong quarterly snapshot from Amazon.

Financial analysts predict the e-commerce giant will report on Thursday that its first quarter earnings and revenue surged past its results from a year earlier. Amazon has boosted its profits in recent quarters by expanding into businesses such as cloud computing services and advertising.
