Investors should hold physical gold as a hedge in a market meltdown, some experts have advised, as equities continued their wild ride on Friday.
Jeffrey Nichols, a senior economic adviser to metals seller Rosland Capital, told CNBC's "Squawk Box" if retail investors planned to buy gold as a hedge against the financial risks present in today's stock markets, they should invest in gold they could hold in their hands.
Nichols said the best insurance for most investors was to have 5 to 10 percent of their investable assets in bullion coins such as American Eagles, Maple Leafs or Kruggerands, among others.
They are "the most liquid form of physical gold," he said. "Once you have got that, if you want to speculate or trade gold, you can trade derivatives, options, futures, and so forth," he said, adding that bullion coins had the extra advantage of being difficult to counterfeit.
Adrian Day, president at Adrian Day Asset Management, agreed. He told CNBC's "Street Signs" that investors should "start with bullion, it is the hedge, the security, the insurance," before going into gold mining stocks for leverage and speculation.
Gold is considered a safe-haven investment during times of market turmoil, and recent volatility has helped spot gold rise 17.1 percent this year to $1,242.70 an ounce on Friday. Gold mining stocks have also seen some big gains this year, with South Africa's Harmony Gold soaring 162.62 percent since the start of 2016.
At the same time, financial markets have come under tremendous pressure in a low growth, low interest rate environment. Concerns over China's economic slowdown, tepid global growth prospects and tanking oil prices are just some of the reasons why equity markets have sold off heavily since the beginning of the year.
The S&P 500 index, one of the most widely followed indexes, is down 5.7 percent for the year. Japan's Nikkei 225 is off 17.4 percent and China's Shanghai composite is 22 percent lower for the same period.
One reason why gold is seeing an uptick in demand is because many investors, particularly institutions, are underweight gold, according to Day.
"One of the biggest things is gold is a hedge [against monetary turmoil]. Over the last several years, a lot of investors, particularly institutional investors, hedge funds, they didn't just need gold because they were making money elsewhere," the fund manager said.
Currency markets struggled to stabilize, meanwhile, while being pushed by forces including a pull-back on yen carry trades, uncertainty over the Fed's hiking path and bearish bets on the yuan.
The dollar index, where the dollar is weighted against a basket of currencies, is off 2.91 percent for the year. A strong dollar has traditionally been a headwind for gold, because gold is priced in dollar terms, so a weaker greenback makes gold even more attractive.
