Mary Anne and Pamela Aden are among the advisory world's top authorities on metals and resources.

In a recent Q&A session, the editors of The Aden Forecast answer the most common questions that they are asked by readers as to the current state and future outlook for the precious metals markets.

In addition, the sisters answer what they say is the most frequent question they receive: "What is the best way to buy gold." Here, they offer a review of five strategies for investing in gold, including their top picks among stocks, closed-end funds and ETFs.

Using a proprietary "volume reversal" trading strategy, Mark Leibovit has been consistently ranked among the top newsletter timers. In his VRTrader, he looks at the outlook for stocks, oil, gold & silver -- and offers his choice for exchange-traded funds for traders to play these markets.

Leibovit explains, "The stock market's decline, besides being huge, is relentless. Every rally was met with selling and fresh lows were soon hit. The Dow crashed through the March and January lows and is now trading at its lowest level since September 2006.

"Apparently, that 1500 point rally off the March low was just a giant head fake. The Dow is now down 19% since last October and the S&P is down 18%, approaching bear market territory."

"Breadth is dismal, and down volume is ten times greater than up volume. Sector action is terrible. Seven of the nine market sectors are down more than 2.5%. Ouch! Financials have done it again and have set a new five-year low. Oil spiked through previous records setting a new record high.

"The precious metals also showed strong gains today with gold up 32.80 to 915.10. We cleared the June 9th high of 907.20 touching 909.50 opening up potential to 931.00 (May 21 high).
