The "Fast Money" traders weighed their "Brexit" playbooks, after a Monday poll revealed that support for Britain leaving the European Union has grown.
Fifty-three percent of respondents now favor a British exit from the EU, according to a poll released by The Guardian and ICM. Commodities investor and CNBC contributor Dennis Gartman told CNBC that a vote to leave would put pressure on the sterling and other European currencies, while a vote to stay could lead to gold trading lower.
In an environment where it's hard for traders predict what's going to happen, Trader Steve Grasso said it's best to "stick with what's working." Grasso likes the VanEck Vectors Gold Miners ETF, which is up nearly 89 percent in 2016.
"I'm using the outperformance of the GDX. I think it goes higher in any market. It may back up a little bit, but ultimately the trade is higher," he said.
Trader Guy Adami agreed, saying that the fundamentals of the gold rally aren't predicated on "Brexit" fears.
"[The rally] started when the Japanese went to negative interest rate policy. That's not going away any time soon. I think as long as rates stay lower, gold goes higher," he said.
"Spreads were widening today in the 10-year in those two parts of the world when, today, everywhere else was seeing yields plunge," he said.
