UK stocks edged lower Friday, with bank shares keying off losses on Wall Street where worries about progress for tax cuts and other reforms ramped up, but the blue-chips market remained on course for a weekly advance, MarketWatch reports.

What markets are doing: The FTSE 100 index shed 0.1% to 7,439.51, led by the financial and healthcare groups. But the basic materials sector topped advancers. On Thursday, the benchmark fell 0.7%, the largest percentage drop since Nov. 30, according to FactSet data.
