The full stock symbol for the company is BBD the ".B" refers to a class of stock in that company....just as there are b class shares there are also ".A"s and (I believe) ".C" shares.
BBD.B is the most commonly traded class of common shares issued by Bombardier. There is also BBD.A but those are 10 votes per share and are 80% held indirectly by the Bombardier family.
