After markets closed, Facebook (Nasdaq:FB) reported stronger-than-expected revenue in the company’s first earnings report since its rocky initial public offering two months ago. Revenue grew 32 per cent to $1.18 billion, which beat estimates of $1.16 billion. Adjusted earnings of US$295 million, or 12 cents per share, matched Wall Street’s expectations. Its shares fell 10.6 per cent or $2.85 in after hours trading to $23.99.
The eurozone debt crisis has weighed on stock markets for over two years. Greece, Portugal and Ireland — all countries saddled with huge debts — have been forced to seek bailouts. The crisis has more recently moved to Italy and Spain, which have been forced to pay ever higher yields in order to finance their debts.
Market watchers took Draghi’s comment as a signal that the ECB could be more willing to intervene in markets to lower those borrowing rates — which the bank has in recent months said is not part of its mandate.
Market sentiment had also been given a boost already on Wednesday, when ECB policymaker Ewald Nowotny suggested that Europe’s bailout fund could be given a banking licence. That would give it the ability to borrow money from the ECB. Such a move would be of particular significance for Spain and Italy as the current bailout fund does not have enough money to rescue them both.
The yield on Spain's 10-year government bonds fell sharply following Draghi's comments, moving down 40 basis points to 6.94 per cent. Anything over seven per cent is considered unsustainable in the long run.
Despite the positive reaction on markets, there was some skepticism that the eurozone crisis has turned a corner.
"It remains to be seen," said Garey Aitken, director of equity research at Bissett Investment Management in Calgary.
"Maybe it does translate into something that is quite significant and positive but really pretty much all comments, intentions, summits, (in the past) the end result has been much more disappointing than the original hope."
The prospect of further ECB action helped take some of the sting from a run of largely disappointing earnings reports.
Hopes for higher demand and a weaker U.S. dollar pushed commodities higher.
