Sony and Toyota, two major Japanese companies are expected to return to profit in the second quarter. And that's led to rise in their stocks.

The electronics maker is expected to bounce back from an operating loss, on solid sales and cost cuts. Toyota is also expected to record a quarterly group operating profit, compared to a loss in the same period last year. Toyota has been plagued by safety crises, that led to a recall of over 10 million vehicles globally. Sony will announce earnings on Thursday, while Toyota will release results in early August.
