FURIOUS (Ad)

Marc Chaikin wrote the software now found on $25,000 Bloomberg Terminals used by professional Wall Street traders. He had walked away from the industry - until his wife Sandy's retirement savings were decimated by the very insiders he had built his system for. That experience drove him to reimagine his institutional-grade stock analysis system for independent investors. The result is the Power Gauge - designed to give everyday investors the same informational edge as Wall Street professionals.tc pixel

Iran's New Leader Just Said Something That Should Terrify Every American (Ad)

Iran's Supreme Leader has declared the Strait of Hormuz closed as leverage against the U.S. - and with 40% of the world's oil passing through that corridor, crude has already crossed $100 per barrel. History shows gold surged 571% during the 1973 oil crisis and 425% in 1979. Today, the U.S. holds 8,133 tonnes of gold valued on the books at $42.22 per ounce - while gold trades above $5,000. American Alternative Assets has released The Great Gold Reset report detailing what this gap could mean for investors.tc pixel
