- FTSE 100 bounces off lows but still firmly lower- Index at six-week low, finishes January down 3.5 per cent- Eurozone CPI ramps up pressure on ECB- BT leads risers on upbeat guidancetechMARK 2,774.88 -0.20%FTSE 100 6,510.44 -0.43%FTSE 250 15,674.37 -0.17%The UK stock market finished the week in a choppy fashion as sharp losses suffered this afternoon were partly erased by the close of trade amid mixed economic data and corporate earnings from across the globe.After a slow start, equities had sunk sharply into the red after an unexpected drop in Eurozone inflation renewed concerns over deflationary risks in the single-currency region.Meanwhile, worries over the outlook for emerging markets that have weighed on stocks over the past week were continuing to hamper risk appetite today.The FTSE 100 finished 28.01 points lower (-0.43%) at 6,510.44, having bounced off its intraday low of 6,421.26 reached after midday. Nevertheless, the index still finished 2.3% lower than last Friday's closing price of 6,663.74, ending the month of January down 3.5%. It is now at its worst level since December 18th.Stocks on Wall Street also started on the back foot after some disappointing earnings from blue chips Wal-Mart, Amazon.com and Mattel, along with a host of mixed economic indicators. US personal spending growth, a gauge of business activity in Chicago and the University of Michigan consumer confidence index all eased on the previous month, although the latter two came in slightly ahead of expectations.Eurozone inflation ramps up pressure on ECBDespite Mario Draghi's insistence earlier this week that last month's fall in inflation was just a blip, the annual rate of Eurozone consumer price inflation eased back to a four-year low of 0.7% this month. This was down from 0.8% the month before and further below the European Central Bank's (ECB) target for inflation close to, but under, 2%.This will now ramp up the pressure on the ECB President ahead of the policy meeting next week, given that inflation is now running at the same level it was in November when the ECB cut interest rates to a record-low 0.25%."The problem the ECB now faces is that any interest rate cut to, say, 0.1%, will probably have minimal impact, which means they will be forced to consider more unconventional measures," said Market Analyst Craig Erlam from Alpari UK.BT ups full-year guidanceTelecoms titan BT was a high riser after raising its earnings outlook for the year as its broadband fibre business and new BT Sport channels helped it to boost profits by 8% in the third quarter.Next, which announced on January 3rd that it would pay a special dividend of 50p per share to shareholders on February 3rd, said it would make a further special dividend payment of 50p on May 1st, giving the stock a boost.Drinks group Diageo was extending losses made yesterday when it disappointed investors with worse-than-expected first-half results after a slowdown in emerging markets.
