Yes, If you know what you will invest on. No, If you don't know what your investment is. My suggestion is never put all your eggs in one basket (i.e. need to diversify). I learned the hard way during the past recession 2007-2009, lost 50% of my capital by not fully diversify. But this month, I have earned all my capital back and more.
Regarding gold, I never a fan of gold especially right now. Everyone mention gold even the TV ads about gold is rising. Looks like a bubble to me. Though if you want to invest in gold, try to get in slowly through Gold ETF (i.e. GLD) or Gold miners stocks.
Final advise, please do your own research before invest in anything.
