Winter has come early for Apple, and it might last a while. 

The world’s largest company by market value has become worth considerably less over the past three months. Apple’s share price has slid 11% since the company reported its fiscal third-quarter results on Aug. 3, erasing nearly $400 billion in market value. It is hardly a typical swing given the fact that the company has long used the fall season to launch its biggest products for every year, including new iPhones.
