Earnings disappointments from Amazon and Apple could make for a sour start for stocks Friday. One analyst expects Amazon shares could take the brunt of it.
Has the Apple stock, which gained more than 70 percent this year, seen its best days? Shares of the tech giant have shed more than 14 percent since hitting an all-time high of $705 in September, compared to the S&P 500 which lost 3 percent in the same period.
