The major U.S. indexes moved higher over the past week despite weak new and existing home sales. New home sales fell to a sharply lower-than-expected annualized rate of 571,000, while existing home sales fell 1.3% to an annualized rate of 5.44 million. The primary driver behind the stock market rally has been better-than-expected second quarter earnings, higher expectations for tax reform and more dovish expectations for the Federal Reserve.

International markets moved lower over the past week. Japan's Nikkei 225 fell 0.09%; Germany's DAX 30 rose 0.02%; and Britain's FTSE 100 rose 1.2%. In Europe, the European Central Bank's plans to phase out its massive stimulus program early next year could slow down the region's strong recovery. In Asia, economists are concerned that a crackdown on backdoor borrowing by local governments in China could put a drag on growth. (See also: Time to Buy Alibaba Bonds? BofA Merrill Thinks So.)
