Is there a general guideline for what percentage of a portfolio should be in gold?
Gold's valuation is so stratospheric right now that I wonder if negative numbers (as in, you should short it) are acceptable in the short run.  In the long run I'd say the answer is zero.  The problem with gold is that its only major fundamental value is for making jewelry and the vast majority is just being hoarded in ways that can only be justified by the Greater Fool Theory.  In the long run gold shouldn't return more than inflation because a pile of gold creates no new wealth like the capital that stocks are a claim on and doesn't allow others to create new wealth like money lent via bonds.  It's also not an important and increasingly scarce resource for wealth creation in the global economy like oil and other more useful commodities are. I've halfway-thought about taking a short position in gold, though I haven't taken any position, short or long, in gold for the following reasons: Straight up short-selling of a gold ETF is too risky for me, given its potential for unlimited losses. Some other short strategy like an inverse ETF or put options is also risky, though less so, and ties up a lot of capital.  While I strongly believe such an investment would be profitable, I think the things that will likely rise when the flight-to-safety is over and gold comes back to Earth (mainly stocks, especially in the more beaten-down sectors of the economy) will be equally profitable with less risk than taking one of these positions in gold.
