Does anyone know how Canadians can buy these? Are they worth it?Just so you know, my lawyer doesn’t allow me to invest in individual commodities anymore. I only buy indexes now. I buy the Rogers Commodity Index, or the Rogers Agricultural Index or the Energy Index, depending on how I feel when I want to buy something. They’re based on futures. As I’m sure you know, investing in indexes outperforms active management 75 to 80 percent of the time year after year.
