I don't know.

I don't consider gold an investment. It is a currency from my perspective (others may consider it differently). It is the only currency not being debased and its rate of inflation is mine output minus whatever gold is consumed in industrial uses that does not get recycled (which figures out to about the rate of population growth).

Six months is short term (from my perspective) and I don't look at "investments" from that short term view. A six month time period I would consider a speculation or trade and I'm lousy at that so don't even try.

Corn and soybeans I produce so I look at them as a source of income rather than as an investment. Land I would consider an investment.

That leaves only silver among the group that you mentioned that I would even consider an investment.

Long term, I like silver (3-10 years). It has good supply demand fundamentals. Short term, I don't do.
