- EU leaders agree to banking supervisor by January- Aggreko and Bunzl lead fallers in London- US heavyweights disappoint with Q3 resultsThe FTSE 100 index had sunk firmly into the red by the close on Friday as investors awaited further news from the European summit. Aggreko and Bunzl were registering heavy losses in London after disappointing updates, while banking stocks were also out of favour.So far, European leaders have announced that they would set up a Eurozone bank supervisor run by the European Central Bank (ECB) by the end of the year. "We have a date in place now for the legislative framework, which we didn't have before - and that in itself is an important step forward," said European Council President Herman Van Rompuy. "Global markets rode cautiously today as investors rejected the proposal by the EU to create a single Eurozone banking supervisor to aid struggling banks and provide them with access to the European bailout fund, if need be," said financial trader Shavaz Dhalla from Spreadex this afternoon. "It seems investors are becoming frustrated with the continuous proposals outlined by EU policy makers to resolve the debt crisis but failing to provide investors with specific information regarding how the fund will operate, the time scale involved and perhaps more crucially, how much funds will be needed."Markets have also been dampened by worse-than-expected third-quarter results from some US heavyweights over the past 24 hours, including fast-food chain McDonalds, tech giant Microsoft and American conglomerate General Electric. In domestic news, UK public sector borrowing was £12.8bn in September, below the £13.5bn registered in the same month of 2011 and under consensus estimates. FTSE 100: Aggreko and Bunzl disappointShares in temporary power and temperature controls group Aggreko tanked after a more or less 'in-line' third-quarter statement was dampened by some disappointing guidance with extra bad debt provisions and adverse foreign exchange rates expected to dent its bottom line. Although many analysts chose to remain upbeat about Aggreko's long-term potential - Investec, Seymour Pierce and Jefferies all maintained their 'buy' ratings on the stock - shares were down nearly 8%. Distribution and outsourcing group Bunzl was a heavy faller after the third quarter saw a moderation in the underlying revenue growth rate, particularly in North America, where the company is going up against tough comparatives. Oriel Securities cut its view on the stock to 'hold' this morning.Barclays continues to trade lower after announcing last night that it has set aside a further £700m in provisions against the possible costs associated with compensating customers for mis-sold payment protection insurance (PPI), taking it total provisions to £2bn. Meanwhile, according to reports, the bank is planning to cut around 10% of its staff from its EMEA equities division in an effort to reduce costs, according to reports.Sector peers RBS and Lloyds were also out of favour, with the latter being weight down by a ratings cut from JPMorgan Cazenove to 'underweight'. Insurance giant Standard Life was also lower after being hit by a downgrade from Berenberg to 'sell'. In contrast, shares in luxury fashion group Burberry were registering gains after Investec returned to its bullish stance on the stock and upgraded its rating from 'hold' to 'buy'. Analyst Bethany Hocking said: "The Burberry brand is far from broken, operational leverage should come through, and, whilst volatility will remain, we see long-term value here." FTSE 250: Spectris jumps after "resilient" performance Specris saw a robust performance in the final quarter of its financial year and while like-for-like (LFL) sales growth had slowed from the first half, analysts said that this was as expected. The instrumentation and controls company said that reported sales during the last quarter were up 12%. House-builder Redrow was leading the downside after Chairman Steven Morgan last night ditched his plan to buy the company, bringing seven weeks of takeover talks to an end after falling four of Takeover Panel regulations.FTSE 100 - RisersJohnson Matthey (JMAT) 2,329.00p +1.84%Hammerson (HMSO) 483.40p +1.53%Hargreaves Lansdown (HL.) 753.00p +1.41%SABMiller (SAB) 2,633.50p +1.33%Wood Group (John) (WG.) 875.50p +1.21%Tate & Lyle (TATE) 719.50p +1.20%Reckitt Benckiser Group (RB.) 3,701.00p +0.98%United Utilities Group (UU.) 729.00p +0.97%Polymetal International (POLY) 1,166.00p +0.95%Pennon Group (PNN) 734.50p +0.69%FTSE 100 - FallersAggreko (AGK) 2,137.00p -7.17%Evraz (EVR) 248.30p -4.09%Bunzl (BNZL) 1,038.00p -4.07%Lloyds Banking Group (LLOY) 40.49p -3.30%Eurasian Natural Resources Corp.
