From 2017, Gold ETFs and Gold Stocks all over the world are expected to rally to historic all time new highs just as physical gold will rally to historic all time new highs of beyond $1921 and beyond $2000 respectively.
Reiterate: Investors owning stocks and equities must have some gold or gold ETF or gold index in their holdings to stablise their portfolio. Because when stocks rally, Gold can rally, it can also correct healthily, but when stocks fall, gold will rally. The effect is that if gold corrects within the portfolio, it will force one not to overbuy stocks. If gold spikes up in stocks' sell-off, it will extinguish your fear as your portfolio is protected and balanced off by gains in gold. If both equities and gold rally, which is what I expect, you stand to gain from both concurrently. You have the best of all worlds.
