Is it safe to invest in an index fund?

Investors may base their investment decisions on fundamental analysis. These investors analyze the macroeconomic situation, which includes international economic indicators, such as GDP growth rates, inflation, interest rates, productivity, and energy prices. They would also analyze the total global gold supply versus demand. Over 2005 the World Gold Council estimated total global gold supply to be 3,859 tonnes and demand to be 3,754 tonnes, giving a surplus of 105 tonnes . Others point out that total mine production is only about 2500 tonnes each year, leaving a 1300 tonne deficit that must be made up by central bank or private sales.. While gold production is unlikely to change in the near future, supply and demand due to private ownership is highly liquid and subject to rapid changes. This makes gold very different from almost every other commodity.
