The FTSE 100 looked set to deliver its third consecutive day of gains on Thursday as markets continued to rebound following some heavy falls over the last month.After a heavy fall on Monday to a fresh five-month low of 6,029, London's benchmark index has rebounded strongly over the last two sessions, finishing last night at 6,165.There will be a raft of economic data from across the globe today for traders to digest, including German unemployment figures and Eurozone consumer confidence this morning, as well as jobless claims, personal income/spending and pending home sales in the States this afternoon.The final reading of first-quarter UK economic growth is also due out this morning in the wake of George Osborne's spending review yesterday in which he detailed a 2.7% cut in real departmental current spending. UK gross domestic product (GDP) growth is expected to be in line with the 0.3% quarter-on-quarter initial estimate.Benchmarks in the States finished higher last night as markets reacted positively towards a downwards revision to US GDP growth to 1.8% in the first quarter, down from the initial estimate of 2.4%."Clearly investors are now hoping that the Federal Reserve will rethink their decision to taper stimulus measures and instead will continue with such measures which seem to be the key catalyst driving the markets at the moment," said Financial Trader Shavaz Dhalla from Spreadex.However, as some have pointed out, this data is still three months old and most economic data as of late has continued to improve.Markets were also reacting positively to comments from European Central Bank (ECB) President Mario Draghi who yesterday said that the ECB would maintain its easy-money policy for the foreseeable future. He said that Draghi the act of exiting accommodative policy "remains distant" and the ECB is keeping an "open mind" about using all non-traditional policy instruments. FTSE 100: Miners rebound, but ENRC fallsMining stocks were performing well this morning, including Glencore Xstrata, Randgold, Antofagasta and Vedanta, with the sector rebounding after heavy falls the day before as metals prices slumped.However, sector peer ENRC was a heavy faller after UBS downgraded the stock from 'buy' to 'neutral' and cut its target price to reflect this week's lower offer from its founding shareholders and Kazakhstan government.Energy services group John Wood Group gained after saying it is on course to deliver good growth in the first half and remains confident of achieving full-year performance in line with expectations.FTSE 250: DS Smith jumps early on after resultsPaper and plastic packaging company DS Smith jumped this morning after seeing pre-tax profits soar 51% to £166.2m following a "transformational year". Revenue for the year to end of April jumped 86% to £3.6bn, boosted by the acquisition and integration of SCA Packaging. However, digital sports media firm Perform dropped this morning after a pre-close trading update said that while it is on track to deliver strong revenue growth this year, a change in revenue mix, together with additional rights and other investment, will impact the rate of earnings growth.FTSE 100 - RisersSmiths Group (SMIN) 1,300.00p +2.36%Glencore Xstrata (GLEN) 282.25p +2.26%Randgold Resources Ltd.
