Say I have GPB 2500 to invest. How would I best tie my money to the cost of energy, or food staples? I don't want futures since I don't want a geared investment, or losing more than my original amount. Too many people doing this will help inflate the speculative bubble, but timing is everything...
I know about buying shares from an on-line broker, but I only recently heard about exchange traded commodities.
I also don't really want a fund, with a manager taking most of the profits, but am willing to pay an amount per trade (similar to shares).
