Is this money you may be needing in the next couple years? If so (and you indicate you want safety), you want to take less risk than if you won't need it for a long time. You will at least want to keep enough in a safe, liquid form to be able to cover all your expenses for a year (they used to say about six months but given the current employment situation I would want a year) should you for some reason lose your income source. I would not put that money into stocks or metals. But having said that, where I have a block of my "emergency fund" is in a stock- a dividend paying utility stock. Look into DRIPs or Dividend ReInvestment Plans- the cheapest way to invest in stocks (lower costs means higher returns). I get a guaranteed return with the dividend and utility stocks tend to be pretty stable so are less risky than other stocks. I keep another chunk (at least three months expenses) in a basic bank account. Low interest but safe keeping for the money. Having a reserve was critical the last time I found myself out of work- and it took 11 months to find a new job.
