The Toronto Stock Exchange closed the day up 159.2 points on Wednesday — equivalent to 1.11 percent — largely on the back of rising oil prices and energy stocks. Oil prices rose $1.73 to just under $79 a barrel from lows in the $76 range on Tuesday. While still not above the $80 mark, and far off the preferred $90-per-barrel benchmark, the rise was still encouraging for investors and analysts, especially given that West Texas Intermediate crude hit its lowest price in three years on Tuesday morning. Wednesday's good news came on the back of lower US oil production last week, when just 500,000 barrels were produced. The original estimate from the Energy Information Administration was for 1.2 million barrels, which would've taken a bite out of depressed oil prices. Chesapeake Energy (NYSE: CHK) encapsulated the gains seen on Wednesday, releasing third-quarter profits more than triple the same time last year. The company posted a profit of $662 million with 725,600 barrels of oil equivalent produced a day. Chesapeake's revenue increased 17 percent, to $5.7 billion, driven by a 48-percent revenue spike in natural gas, oil and natural gas liquid sales. The company's share price ended the day up 6.9 percent, at $22.76 per share. Staying positive But while the news from Chesapeake provided a welcome boost to investors, analysts remain wary about Saudi Arabia's involvement in setting oil prices. The Middle Eastern juggernaut is looking to compete with the cheap shale oil boom in the US, and is cutting the price of oil to its US customers. "In their minds, they think why should they cut back production and let the U.S. continue full steam ahead?" said Allan Small, senior adviser at HollisWealth.
