No way would I invest in a gold stock mutual fund. You cannot get out of a mutual fund intraday. Instead, go with an exchange traded fund referred to as an ETF where you can place sell stop limits (or buy stops if short). IAU and GLD are two to look at.

You're like me you trader! Of course it would depend on Rooster's style of investing. I'm glad you did bring these up.
