Two weeks ago, companies were expected to report a decline in earnings.Investors also looked to the U.S. Federal Reserve, which wraps up its two-day meeting Wednesday. Policy-makers are expected to further trim the central bank’s bond-buying program and provide further insight into the state of the world’s biggest economy.Traders will also look for further indications of when the Fed might start to raise short-term interest rates, which have been near zero since the financial crisis.Suncor’s performance helped send the energy sector up 1.6% as June crude in New York rose 44 cents to US$101.28 a barrel. Traders will be taking in earnings from other heavy hitters in the sector this week, including Cenovus (TSX:CVE), Imperial Oil (TSX:IMO) and Canadian Natural Resources (TSX:CNQ) amid a sharp change in the fortunes for these companies.One of the improvements revolves around a sharp narrowing in the price between oilsands crude, known as Western Canadian Select, and West Texas Intermediate, a lighter crude used as the U.S. benchmark.“That narrowing has gone from roughly $31 at the end of the fourth quarter last year to $21, so that’s a 33% improvement right there,” observed John Stephenson, portfolio manager at First Asset Funds.He also pointed out that the Canadian dollar weakened in the quarter.“So you have an industry where you’re getting revenues in U.S. dollars and paying expenses in the lower Canadian currency, so you’re making a spread there. And there’s a record number of deals and activity happening in the oilsands year to date.” July copper was down two cents to US$3.07 a pound and the base metals sector rose 1.13%.Gold faded $2.70 to US$1,296.30 an ounce and the sector was up about 1%.In other corporate developments, Quebecor Inc.
