Commodities "investing" goes something like this:
I'll bet you the price will go up
Response: I'll betcha it'll go down. How much ya wanna bet?
Stock market investing puts money into a system that historically has created wealth. Commodities investing puts money into a system that has a loser for every winner.
...no kidding....I've invested for 30 years and been a broker for over 15....and I would not touch the commodities market for me or my clients....except the already wealthy who want to really develop 10% as a hedge to their asset allocation....many newbies are getting in now and they don't realize unlike the stock market....you can lose everything....and quickly.....oh, but how they learn a lesson....
