While stock markets are on a tear since their declines in May this year, the office supplies retail sector has not been doing so well. Sales, profits and revenues have been declining , leaving the office supply retail sector in a bind. Take the smaller player in the industry Office Depot (ODP), with a 450 million market cap, which last June closed all its Canadian retail locations. Office Depot has a razor thin profit margin of only 1.01%. When I looked at the office supply sector back in May 2011, Office Depot was worth over 1.1 billion dollars.
