Gold did this exact thing in 1975… [then exploded] (Ad)

In 1975 the Fed raised rates and gold fell 50 percent. Headlines called the gold bull market dead. Instead gold climbed from 100 dollars in 1976 to 850 dollars by 1980, a 750 percent gain in under five years. Today the new Fed chair has floated another rate hike, and investors are reacting the same way they did in 1975. Analyst Garrett Goggin, CFA, CMT, founder of Golden Portfolio, says the setup rhymes with that era.tc pixel
