Investing

Analysts from commodities investment firms say that the recent run in oil prices will be short-lived, with some evidence of a dip during today's trading.

Would you suggest opting for an alternative?

Natural gas--though there's a huge supply that's currently keeping prices low?

Soy--prices have gone up enormously over the past month, but may be overpriced, as well?

Precious metals--even though they may not do so well once the market recovers?

I'm a firm believer in Peak Oil, but I have a sense that Americans won't feel the effects of it until another 10-20 years from now.

With regard to the individual investor, is the belief that one should "buy and hold" now extinct in the current market?
Word has spread rapidly that we're in a traders' market and that current long term (roughly 5-10 years) investments are uncertain.

Given the current market rally, especially in commodities, would you consider it to be a good investment opportunity for long-term investors? I ask after reading about growing demands for natural resources from China and other industrializing nations.

Also, would you recommend that an investor choose ETFs in commodities or directly invest in commodities themselves? And would it be a wise investment for future retire planning?

Thanks,
