U.S. stocks logged a three-day losing streak on Friday to finish the week lower, with the Dow Jones Industrial Average marking its biggest drop this year, as economic data came out tepid.

Meanwhile, the 10-year and 30-year U.S. Treasury yield hit their highest levels in two years amid the ongoing worries about when the U.S. Federal Reserve will start to trim its monetary stimulus policy. On the economic front, U.S. homebuilders broke ground on more homes in July boosted by apartment construction, evidence of a recovering property market, the Commerce Department reported on Friday. Data showed U.S. privately-owned housing rose 5.9 percent in July, but the figure came in lower than expected. Meanwhile, U.S. consumer sentiment for August slipped from a six-year high. The preliminary reading on consumer sentiment fell to 80.0 in August from 85.1 in July, according to the Thomson Reuters/University of Michigan index. \"Consumer confidence declined from a six-year high, which implies consumers are vulnerable to rising rates and dropping stocks. If the Fed starts tapering in September, causing rates to climb and stocks to drop, consumers may pull back spending, which could slow the economy again,\" Mei Li, an economic analyst at FTN Financial, commented in a note on Friday. Moreover, non-farm business sector labor productivity grew at an annual rate of 0.9 percent in the second quarter of the year, as output increased more rapidly than hours worked, the Labor Department said on Friday.
