Apple Inc, the largest U.S. stock by market value, was headed toward its eighth straight week of declines on Friday
Since hitting a record high of $705.07 a share in September, Apple has lost about a quarter of its value. The stock's descent has vastly outpaced those of the S&P 500, which is down just under 7 percent in the same time frame.
Apple's stock has been below both its 14-day and 50-day moving average for over a month, suggesting both the short- and mid-term momentum is negative.
