Dan Deming talks the commodities market. He thinks if gold can hit $3,400, it could “indicate the potential for further gains.” He thinks a weaker dollar will give it a tailwind for “several years.” He looks at platinum and silver, which have both seen strong runs this year. Dan points to $70-$72 as key levels to watch in crude. He also warns traders not to get “too comfortable” with Bitcoin’s recent gains, since the product remains volatile.
