European stocks closed lower Friday afternoon, tracking declines in U.S. stocks after tech titans Amazon and Google parent Alphabet Inc missed earnings expectations.
The pan-European Stoxx 600 ended down 1.21 percent at the provisional close. The U.K.'s FTSE 100 traded down 1.4 percent, while France's CAC 40 and Germany's DAX lost 1.4 percent and 1.8 percent respectively.
On the week the Stoxx 600 lost 2.9 percent in value.
Third-quarter earnings season has been overshadowed by sell-offs across global markets and sharp downgrades to corporate estimates.
Nonetheless, weaker-than-expected results from Amazon and Alphabet Inc overnight exacerbated investors' worries about the dominance of tech stocks in this market cycle.
In Europe, every sector closed lower with media and telecoms stocks leading the declines.

Meanwhile, oil refiner Neste surged higher Friday morning, after the company beat expectations with third-quarter results. The company said it expected 2018 to be a very strong year for the firm. Its shares had bounced 10.47 percent.
