Diane King Hall talks all A.I. trade developments moving markets Friday morning. Applied Materials (AMAT) sold off more than 10% after it posted disappointing guidance and hinted at China tariff pressures. Cisco (CSCO) faced pressure of its own after HSBC downgraded the stock from buy to hold. Diane noted one bright spot in Salesforce (CRM), which got an upgrade from DA Davidson as the firm sees competition and decelerating growth already baked into shares.
