Apple shares hit all-time high ahead of expected launch of new iPhone models

Gold smartphone and an Apple Watch with a larger display are expected at company's regular September gathering

Apple shares hit record highs on Thursday after it said it would host an event on 12 September at its Cupertino campus where it is widely expected to unveil new iPhone models.

At one point its shares rose to more than $228 each amid speculation that Apple plans to release three new smartphones this year, including one with a larger display than previous models. Analysts also expect Apple to release an iPhone with a edge-to-edge display similar to the iPhone X but using less-costly LCD screen technology.
