PARIS, March 31 (Reuters) - European stocks edged higher early on Wednesday, heading for their fourth consecutive quarterly gain, led by rallying banks while steady oil prices boosted energy stocks.
Bank of Ireland <BKIR.I> soared 27 percent after saying it was in talks with investment banks to raise capital to plug a hole left by property loan sales to the Irish bad bank, the National Asset Management Agency (NAMA).
At 0837 GMT, the FTSEurofirst 300 index of top European shares was up 0.2 percent at 1,081.69 points. The benchmark index had a roller-coaster session on Tuesday, hitting an 18-month high before surrendering gains and ending the day flat.
The index, which is up around 68 percent from its record low hit in March 2009, is on track to record a gain of 3.4 percent for the quarter.
But the market has been stuck in a range over the past week.
"Markets were rocky at the peak of the Greek crisis, but now volumes have fallen again, the newsflow has dried up, there is no catalyst," said Jacques Henry, analyst at Louis Capital Markets, in Paris.
"Unless we get some sort of surprise on the macro data front, like with the payrolls this week, the market might move sideways for a bit."
Investors remained cautious ahead of monthly ADP employment report, expected at 1215 GMT on Wednesday. The data is usually seen as a harbinger for the key U.S. non-farm payrolls numbers, due later in the week.
The median forecast for U.S. nonfarm payrolls is for a rise of 190,000 in March after falling 36,000 in February. [

Mining shares reversed early losses and moved higher, with Anglo American <AAL.L> up 1.2 percent, Eramet <ERMT.PA> up 1 percent and Xstrata <XTA.L> up 1 percent.

With the FTSEurofirst 300 hitting an 18-month high on Tuesday, stocks in the index trade at an average of 14.6 times earnings, according to Thomson Reuters data.
Despite modest gains made by stocks so far this quarter, the average price-to-earnings (P/E) ratio of European stocks has been drifting lower since peaking at 15.9 in mid-January, following relatively strong corporate results.
This compares with a current P/E ratio of 17.5 percent for Wall Street's S&P 500 index <.SPX>. (Editing by Sharon Lindores)
