This is CNBC's live blog covering European markets.

European stock markets closed marginally lower Friday, rounding off a largely negative week for global stocks as third-quarter earnings season ramped up.

The pan-European Stoxx 600 has shed 1% over the week, and was down another 0.04% by Friday's close. Travel stocks led losses, down 1.5%.

Corporate results have proven a mixed bag, with many banks beating expectations but other sectors keeping investor sentiment wary.

Mercedes shares fell 1% after the German automaker reported a 64% plunge in operating profit in its core cars division, blaming "weaker macroeconomic conditions and fierce competition, mainly in Asia."

French spirits maker Remy Cointreau dipped 0.7% after slashing its sales outlook for the full year, saying it now expects a double-digit decline rather than a gradual recovery amid weakness in the U.S. and Asia-Pacific. High-end European drinks firms are being hit by higher duties on their Chinese exports, in a retaliatory move for European Union tariffs on Chinese electric vehicles.

British bank NatWest was closed 0.6% higher, paring earlier gains slightly. It breached its highest level since 2011 earlier in the session, after it beat expectations to post sharply higher profits and raised its annual guidance.

Stock markets were mostly higher in Asia-Pacific trade Friday, though Japan's main indexes declined ahead of a general election over the weekend and the Bank of Japan's monetary policy meeting next week.

U.S. stocks were slightly higher Friday, after a mixed session on Thursday in which Tesla's post-earnings rally lifted the Nasdaq Composite and S&P 500.

Europe markets close slightly lower

The pan-European Stoxx 600 was down another 0.04% by Friday's close, with travel stocks leading losses.

The benchmark has shed 1% over the last week.

Another downside surprise on inflation could see ECB cut by 50 basis points: economist

Another downside surprise on inflation next week will raise the risk of a 50 basis point rate cut by the European Central Bank in December, according to Andrzej Szczepaniak, vice president of European Economics at Nomura.

"In terms of the September inflation print, that spooked the ECB, that surprised them materially to the downside. They were expecting 2% to 2.2%, it came in at 1.7%," Szczepaniak told CNBC's "Street Signs Europe."

Euro zone economic growth figures are due on Oct. 30, followed by a flash October inflation print on Oct. 31.

Szczepaniak forecasts the inflation figure to come in at 2%, while consensus analyst expectation is for 1.9% and the ECB's own expectation is around 2.2%, he said.

If the print is 1.9% or above then that would indicate another 25 basis rate cut in December, he said. But a figure around 1.7% would be "a material downside surprise, not just to the ECB but also to analysts, and that could obviously increase the likelihood of a 50 [basis point cut]," he added.

Between now and the December meeting, the ECB will also have the GDP data, November inflation data and November purchasing managers' index figures, he noted.

"If all of those data show deterioration or weaker inflation, much weaker versus analyst and ECB expectations, that will certainly raise the risk of a 50 [basis point cut]."

German business confidence improved slightly, Ifo says

German business confidence improved slightly in October, according to a survey from the country's Ifo Institute, coming after four straight declines.

"Companies were more satisfied with their current situation. Expectations were brighter but marked by skepticism. The German economy stopped the decline for the time being," the Ifo said.

However, in the country's struggling manufacturing sector, businesses were less pessimistic about the future but viewed their current situation as markedly worse, noting a lack of new orders.

NatWest shares jump to 9-year high on raised outlook

NatWest shares rose 4.3% to their highest level since 2015 after the British bank reported sharply higher third-quarter profit and raised its full-year outlook.

The lender reported attributable net profit of £1.17 ($1.52 billion) for the period, up from £866 million the previous year. Analysts expected net profit of around £990 million, according to a company-compiled consensus.

Return on tangible equity rose quarter on quarter to 17% from 16.4%, while its Common Equity Tier 1 ratio, a measure of financial strength, rose 30 basis points to 13.9%.

NatWest said it now expects to achieve a return on tangible equity above 15% for the full year, from a prior forecast of 14%, and for income excluding notable items to be around £14.4 billion, up from £14 billion. It attributed this to "interest rates and economic activity."

The bank has seen higher net loans, with particular growth in commercial and institutional customers, along with its acquisition this summer of Metro Bank's £2.3 billion mortgage portfolio.

Its British rivals Barclays and Lloyds Bank Group also this week beat profit expectations for the third quarter.

"Better income and costs drove the beat today, offset by higher impairments than expected, which does buck the trend we saw from Lloyds and Barclays. That said, default levels remain low at NatWest and that bodes well for performance over the medium term," Matt Britzman, senior equity analyst at Hargreaves Lansdown, said in a note.

Mercedes falls 3.2% after earnings plunge

Mercedes shares opened 3.2% lower after the German firm reported a sharp profit decline in its core cars division for the third quarter amid increasing competition in China.

Earnings before interest and taxes (EBIT) at Mercedes-Benz Cars fell 64% year-on-year to 1.198 billion euros ($1.296 billion) as revenue slipped 6%. Group EBIT was 48% lower.

The company said that within the cars unit, "weaker macroeconomic conditions and fierce competition, mainly in Asia, outweighed improved product availability."

It had already issued a profit warning last month.

Germany's famed automakers are attempting to transition into electric vehicles while facing a weak domestic economy and waning demand in China, the world's largest car market.

The electricity industry is transforming, according to Morgan Stanley, and multiple power producers, grid operators and utilities are set to benefit.
