"Gold's recent move to a new highs clearly reinforces that the metal's six year bull market is alive and well," say leading resources experts Mary Anne and Pamela Aden.
In The Aden Forecast, the sisters -- who have accurately forecast the bull market since its start in 2001 -- explain why they believe this upmove is part of a mega-trend that will last for many years to come.
"As the dollar falls further, gold will continue to head higher. And the unprecedented trade deficit nearly guarantees that the dollar will continue to slide. Lower U.S. interest rates reinforce this as well, and again that'll be good for gold.
"Meanwhile, U.S. dependence on foreign oil and the record high oil price means the trade deficit is going to stay huge. It'll also contribute to inflation by keeping upward pressure on consumer prices.
"So in a way, it's a vicious circle that goes something like this: high oil = large trade deficits = a weak dollar and high inflation. Spending and money creation = inflation, which all = higher gold.
