The Globe and Mail reports in its Friday edition that Badger Daylighting, Quebecor and First Majestic Silver once again top the short-sellers' table. In a Globe special, Larry MacDonald writes that Badger's first-mover status in hydrovac trucks (used for earth excavation) is facing rising competition; Quebecor is a media company where the short interest may largely reflect arbitraging/hedging of its convertible debentures; and First Majestic Silver is a Mexico-based silver miner with some past execution miscues and a large acquisition to digest. Some of the increases in short positions were registered by Canadian Western Bank, Maxar Technologies and WestJet Airlines. Canadian Western Bank is based in Alberta, where the risk of loan losses has grown because of the underperforming economy; Maxar Technologies is diversifying away from a slowing satellite business into digital Earth imagery while carrying a heavy debt load; and WestJet is dealing with higher fuel prices and increased competition from discount carriers. Also on the list is highly indebted Brookfield Property Partners LP, which is focused on commercial properties. The high-yielding stock has been under pressure because of rising interest rates.
