Shares rose modestly after the report, but by the time the conference call was over, the stock was off nearly 5%.

On the call, which lasted more than an hour, Chief Executive Elon Musk praised the strides the company has made with Model 3 production, said he expects profits in the second half of the year and said he had high hopes for the Model Y, the next vehicle in the company’s lineup.
