Analyst downgrades:

When gold recently moved above $1,000 the Aden Forecast presciently noted that the metals were overbought and forecast a "well deserved breather" for the precious metals.

Now, with the setback in metals prices, Mary Anne and Pamela Aden explain, "We can't stress enough that you should stay invested in the major uptrend, which still has years to run. Don't get left behind or shaken out." Here is their outlook on metals and some favorite mining stocks.

"Are commodities the new bubble? Have they replaced the real estate bubble, which replaced the
tech stock bubble, as investors move from one bubble to another? It sure looks like it.

"But the big difference is that this metals and commodities bubble has a lot further to go. Why? Basically, the perfect storm has been gathering and it's going to fuel a mega rise that will likely last for years to come.

"Most important is China and other growing nations, which are keeping demand and prices super strong. China's growth has been astounding at over 9% each year for more than 25 years. During that time, China has lifted 300 million people out of poverty and it's quadrupled the average income.

Pan American Silver Corporation (NASDAQ: PAAS) demonstrates some of the problems with precious metals mining company stocks. No matter the location of operations, all precious metals mining companies are governed by the same set of rules that affect profitability: mining-operations costs, including production costs which can vary widely from mine to mine; grade quality of ore mined, including how much usable by-product is also produced; economy of scale, although sometimes in mining bigger is not of necessity better; and prices of precious metals on the worldwide spot market. A recent PAAS quarterly earnings release illustrates these factors and the damage they can inflict even on well-run mining operations.

The good news for PAAS 1Q 2007 net income is that there was, in fact, income during the quarter: $20.4 million or $0.27 per share compared to a 1Q 2006 loss of $2.8 million or $0.04 loss per share. $10.25 million or $0.13 per share of net income was derived from the decision to sell a portion of mining operations in Russia. 1Q 2007 sales increased 5% to just over $48 million. FY 2007 total production is forecast to increase 31% to 17 million ounces.

The markets saw a third day of selling today. While some may attribute it to the lower retail sales numbers, foreign interest rate worries or North Korean missile tests, I think it just may be the summer trading session. The market has been shooting up like crazy recently and it is time it takes a breather. Summer time has also been a historical rough time for the market as it makes very little in gains. Last summer is a good example of this. Just because the Dow dropped in the beginning of June last year doesn't mean it has to drop in the beginning of June this year; but it is food for thought.

The NYSE had volume of 2.5 billion shares with a paltry 279 shares advancing while 3058 declined for a loss of 174.07 points to close at 9,720.94. On the NASDAQ, 1.4 billion shares traded, 669 advanced and 2,372 declined for a loss of 45.8 to 2,541.38.

With gold turning down from its recent highs, some have questioned whether the 6-year bull market in metals may be ending. According to Mary Anne and Pamela Aden, the evidence points to the opposite conclusion. Indeed, they note, "Gold and silver have everything going for them and their rises have a lot further to go."

Here, the resource experts and co-editors of The Aden Forecast explain the six key factors they see that are pointing to higher metals prices.

The first two reasons are spending and money. They explain, "The world is swimming in money and that's the fuel that's been driving money assets and commodity prices up. But the magnitude of what's currently happening has never been seen before in world history."

The Adens points out that the U.S. is the world's largest debtor nation and "the government keeps spending money it doesn't have."

Since the government doesn't want to cut spending or raise taxes to reduce its debt, they note, "It simply produces money to cover its expenses, which is what governments throughout history have always done, and this amount is also huge."

In fact, in just over the past year, they observe, the amount of paper dollars that've been created is equal to half the value of all the gold that's ever been produced worldwide over the past 2,000 years, which is about $2 trillion. And it's not just the U.S. "Other countries are pumping out money like mad too. In Europe, for instance, money has been growing at the fastest rate in 17 years."
