A slump in the shares of Apple and Twitter on Monday has investors panicked over the implications for the wider tech sector which has been driving the US bull market in the past few years. US markets are setting up for a mixed open on Tuesday ahead of results from media giant Walt Disney. Apple closed at six-month lows and beneath its 200-day moving average after a report indicated the tech giant had lost its top place in China during the second quarter with domestic rivals Xiaomi and Huawei moving ahead in the rankings. It was also revealed Apple has just bought a 43 acre plot near San Jose airport. Companies will often engage in large real estate projects when confidence is at its peak and can foretell a period of slower growth. Confidence has been ebbing out of Apple shares since its last earnings report when the tech giant guided lower for the second half of the year and neglected to single out Apple Watch sales. There is still a lot of long term growth potential for Apple though the likes of Apple Music and a reported move into the auto industry but momentum has turned negative in the short term. A 50% retracement of the rally since April 2014 would take shares back to $104. With Apple responsible for such a large percentage of gains for all the major indices, particularly the Nasdaq; if it’s shares start to languish, wider markets could too. Twitter made new record lows beneath its IPO price in a follow-through from its quarterly earnings that beat estimates but saw shares plummet after management downplayed the social media platform’s ability to grow in its current state. US factory orders are expected to pick up by 1.7% in June after a decline of -1.0% in May. Earnings from Disney, Sprint, Kellogg, Coach, DreamWorks Animation and Time Inc are some of the companies reporting second quarter results on Tuesday. Futures suggest the: S&P 500 will open unchanged at 2,098 with the Dow Jones expected to open 3 points lower at 17,595 and the Nasdaq 100 3 points higher at 4,583.
