"Canadian Oil Sands Trust (COSWF) has clearly lagged broad-based and energy-sector benchmarks alike over the trailing 12 months," says David Dittman.

The contributing editor to Canadian Edge explains, "A series of unplanned turnarounds at the Syncrude operation, of which Canadian Oil Sands owns 36.7 percent, have analysts questioning whether rising costs will ever allow Canadian Oil Sands to really benefit from elevated oil prices.

After seven months of one of the strongest rallies in history, the stock market is showing signs of faltering. From here on out through the rest of 2009, I believe the advance will shift gears, and instead of recording new highs every month, the trend will tend to flatten.

And as we head into the heart of the fourth quarter, I wouldn't bet on the market making many more new highs this year.

The Canadian Oil Sands Trust (COSWF) is an open-ended investment trust that generates income from its 36.74% interest in the Syncrude Canada Ltd. joint venture, which is the world's largest producer of crude oil from oil sands and the largest single-source producer in Canada.

After falling from more than $50 in July 2008 to less than $15 in January 2009, this trust formed a base and then rallied from February to May before settling down for its next consolidation, a cup-and-handle formation.
