European stocks paused from a two-day rally Wednesday, as investors continued to weigh weak economic data against hopes the European Central Bank will introduce new stimulus measures.

The Stoxx Europe 600 index closed the session 0.1% higher on the day, having climbed nearly 2% this week, after ECB President Mario Draghi on Friday hinted at action to spur much-needed growth and combat low inflation.

The euro zone has seen a marked deterioration of economic data in recent weeks, with the region's growth stagnating in the second quarter.

That trend continued Wednesday, as a survey showed German consumer sentiment is expected to decline in September. The monthly GfK survey showed consumer confidence falling to 8.6 in September from 8.9 in August, against a forecast rise to 9.0.

"The ripple effect of Draghi's dovish comments last week has been prolonged by less-than-encouraging macro data so far this week," analysts at Crédit Agricole said.

Bets that the ECB may be edging closer to a large-scale asset purchase program known as quantitative easing has also buoyed euro-zone bonds.

German 10-year bond yields fell to a fresh all-time low of 0.91%. Yields in France, Italy, Spain and Portugal followed suit, hitting record lows. Yields fall as prices rise.

"We have previously seen the market's probability of QE implementation as oscillating in the 40-60% probability range. Following Draghi's speech at Jackson Hole, in which he acknowledged the decline in inflation expectations, this has firmly swung to the higher end of the range," said interest-rate strategists at Rabobank.

Investors also had one eye on geopolitics, as talks between Russia and Ukraine failed to produce a breakthrough for ending the conflict over eastern Ukraine, and Israel and Hamas agreed to an open-ended cease-fire.

The backdrop from other regions was positive too, with U.S. stocks edging up on Tuesday to push the S&P 500 above 2000 points at the close for the first time. In late European trade Wednesday, the index was up a little less than 0.1%.

Activity in currency markets was muted, with the euro a touch higher against the dollar at $1.3191, close to its recent 11-month low.

In commodity markets, gold edged 0.2% lower to at $1,282.60 an ounce, while Brent crude oil declined 0.3% to $102.20 a barrel.

Back in equities, shares in online retailer ASOS PLC soared to close the session over 19% higher, driven by media reports that the company has become a takeover target. Several news outlets reported that its major Danish shareholder Bestseller had been approached by a U.S. bidder for its stake in the company.

Shares in the online fashion retailer have more than halved in value year-to-date. In June, ASOS said that a vast amount of its stock had been destroyed in a warehouse fire, prompting it to go offline for a weekend. ASOS wasn't immediately available to comment.

Portugal Telecom SGPS SA, meanwhile, was the strongest stock on the Stoxx Europe 600 index at the end of the session, rising more than 6% on speculation of merger activity in the Brazilian market.

One of Brazil's largest phone companies, Oi SA, which is in the process of merging with Portugal Telecom, said on Wednesday that it had hired an investment bank to examine the possibility of buying a stake in a rival phone company, TIM Participacoes SA, which is controlled by Telecom Italia SpA.
