Wall Street stocks finished a volatile week on a sour note Friday after disappointing earnings from Amazon and Google-parent Alphabet sparked a selloff in tech shares. The tech-rich Nasdaq Composite Index finished with a loss of 2.1 percent at 7,167.21.

The Dow Jones Industrial Average shed 1.2 percent to end the week at 24,688.31, while the broad-based S&P 500 fell 1.7 percent to 2,658.69, taking its weekly loss to about 3.5 percent. The Dow and S&P wiped out all of their gains for the year in this volatile trading week, which saw markets react to concerns about rising interest rates, the impact of US trade conflicts as well as geopolitical tension.
