LONDON (Reuters) -Intel shares dropped almost 4% in heavy trading in Frankfurt on Friday after issuing downbeat forecasts for both revenue and profit the day before, as investors fretted about the outlook for the chip sector against the backdrop of the U.S./China trade war.

Intel (NASDAQ: INTC ) shares fell sharply in Frankfurt, having lost 6% in after-hours trading on Thursday.

The company’s shares ended Thursday’s regular trading session up 4.37% at $21.49.
