BOMBARDIER INC. (Toronto symbols BBD.A $7.52 and BBD.B $7.50; Aggressive Growth Portfolio, Manufacturing & Industry sector; Shares outstanding: 1.7 billion; Market cap: $12.8 billion; SI Rating: Extra risk) will probably win a contract to build over 200 streetcars for Toronto’s transit system now that rival Siemens AG has withdrawn its bid. The contract has an initial value of $1.2 billion, but that could rise to over $3 billion if Toronto opts to order 400 more vehicles. Bombardier’s annual revenue is about $17.5 billion U.S. Bombardier is a buy for aggressive investors. The subordinate voting ‘B’ shares are the better choice.
