Letco in English...FYI Best GG When the Montreal asset management firm Letko Brosseau decided to invest in Air Canada during the financial crisis in 2009, few people were interested in the action of the air carrier, which was worth a dollar. Letko Brosseau saw an opportunity this price and bought 23 million shares. After more than doubling this stake over the years to nearly 50 million shares, the time has come for the largest shareholder of Air Canada to cash a portion of its profits while the action comes to fring the $ 30 bar on the stock market. Letko Brosseau revealed Thursday in a document filed with the stock market authorities that she had sold for a hundred million dollars of shares of Air Canada during the last two months. A block of shares valued at $ 9 million was released during the October 26th meeting, a few days after the record high of $ 28.70.
