On Friday, as markets collapsed around the world after Britain voted to leave the European Union, investors in one kind of asset did fabulously: owners of gold.
The precious metal saw a huge one-day price jump, increasing in value by $53.35, or 5 percent, to $1,318 per ounce, a two-year high. That's 13 percent higher than it was a year ago.
Adrian Ash, head of research at BullionVault, a London-based gold-and-silver online exchange, said trading volume was extraordinary. In fact, there was as much trading activity by 2 p.m. London time as the exchange usually does in two weeks.
The strength of gold reflected market uncertainty. Gold tends to gain value in times of anxiety, because traders see it as a safe place to store assets that isn't vulnerable to shifts in the value of currency.
Some experts are dismissive of gold because it is - after all - just a shiny metal, but many investors still assign a symbolic value and treat it as a beacon of stability.
"In a world of uncertainty, gold never changes," Ash said. "Gold doesn't do anything; it doesn't even rust. It's absolutely certain in a world of constantly changing values, constantly changing politics and constantly changing risk."
