What percentage of a portfolio should be gold?

While many experts believe that investors should limit 10 to 15 percent of their investment portfolio to investments in gold, there are many factors to consider before making a decision. Most estimates suggest that investments in gold, such as Gold IRA rollovers, should represent only 5 to 10% of your portfolio and no more. This will ensure that your portfolio has room for other investments, such as mutual funds, stocks, P2P lending, etc. Peter Schiff has always recommended keeping between 10 and 20% of an investment portfolio in physical precious metals and Gold IRA rollovers. But how much of that percentage should be in gold and how much should be in silver? The easiest way to add gold to a portfolio is through an ETF called SPDR Gold Shares, commonly known by its symbol GLD.
