Interesting how certain threads come together…I read recently that copper producers are complaining about the skyrocketing costs of sulfuric acid. A few days later, I read about Mosaic, a fertilizer company – about how the rising cost of sulfuric acid could impact its profit margins.

The payoff for investing in a sure thing is lower than usual these days—a 90-day T-bill only pays 1.8%.
