London open: Stocks gain on ECB optimism

- Crucial day for Europe, ECB decision eyed- Bank of England expected to hold fire- Whitbread, Morrisons and miners lead risersSome strong gains from Whitbread, Morrisons and host of miners assured that the Footsie got off to a decent start on Thursday morning, as markets awaited a pivotal policy decision from the European Central Bank (ECB) this afternoon.All eyes are on ECB President Mario Draghi who is expected to reveal details of the bank's bond-buying programme to bring down yields in peripheral nations. "If yesterday's hearsay from unnamed ECB sources is anywhere near close to being accurate then it's certainly building up expectations as to what President Draghi has to say at today's press conference, with the hope that the reality matches yesterday's raised expectations," said market analyst Michael Hewson from CMC Markets.According to media reports yesterday afternoon, unnamed central bank officials have said that Draghi will announce unlimited purchases of short-dated government debt (with maturities of up to three years) that will be sterilised, though the ECB would refrain from setting a public cap on yields. However, according to Michael Fuchs from Merkel's Christian Democratic Union party yesterday, Germany would oppose the ECB's bond-buying plan if it purchases "too much" sovereign debt without ensuring that these nations agree to strict conditions. The UK's Monetary Policy Committee (MPC) will also release its policy decision at noon, though the consensus estimate is for the Bank Rate to be left at 0.5% and the asset purchase programme to be maintained at £375bn. "With the additional £50bn of QE announced in July not due to be completed until the end of October, we expect no change in policy before November," said analysts at Barclays.FTSE 100: Whitbread and Morrisons impress early onHotel, restaurant and Costa coffee owner Whitbread jumped in the opening hour after reporting second-quarter sales growth of 14.8%, up from 13.9% in the first three months of the year.
