Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Canadian Solar (NASDAQ:CSIQ) jumped 13% today after signing a deal to expand manufacturing.

So what: The company agreed to partner with Samsung Renewable Energy to build a solar manufacturing facility in London, Ontario. The plant will begin construction in 2013 and will supply modules to plants like Samsung's 100 MW projects in Haldimand County and Kingston and Loyalist Township.  

Now what: This is a really great partnership for Canadian Solar and helps solidify it as one of the best manufacturers in China. Not a lot of details have been released about the financial impact this will have on Canadian Solar, and with the company reporting losses each quarter, I'm still leery, but strategically, this looks like a good move. Hopefully this will help push the company into profitability later this year or early next year on the back of higher utilization rates and stabilizing prices in the solar industry.
