LINAMAR CORP. $3.71 (Toronto symbol LNR; Aggressive Growth Portfolio, Manufacturing & Industry sector; Shares outstanding: 65.1 million; Market cap: $241.5 million; Price-to-sales ratio: 0.1; SI Rating: Extra risk) gets 85% of its revenue from carmakers, and falling auto sales have hurt its earnings. The stock has dropped 79.1% from $17.77 in February, 2008. Linamar’s new restructuring plan should save it $40 million a year. That should help it cope until the economy improves. Linamar also stands to gain from new government aid packages for the three main North American automakers. Linamar is a buy.
