Obviously, speculation has its place in a portfolio. A small percentage of any diversified portfolio should be devoted to speculation. However, speculation should not be viewed as a means of balancing the portfolio. These days an investment portfolio should be balanced, diversified, and have protection against inflation which can eat away at purchasing power. A portfolio that does not include diversification with gold is not a balanced plan.
Some investors buy Swiss francs in an effort to diversify.
They reason that the Swiss franc is backed by gold and has proven over the years to be a strong and stable currency. While this is a good step, it should only be viewed as an initial step. A truly balanced portfolio also contains a pure gold investment. Gold protects your purchasing power. Over the years paper money declines in value and purchasing power.
