Trying to figure out what Warren Buffett will invest in next is no small task. Although, you can bet it will not be small. In fact, he may try to acquire whole companies because anything else might not move the needle when it comes to increasing shareholder value at Berkshire Hathaway (BRK.A / BRK.B).

This post is a follow up to Serious Money: Buffett Looking Beyond Our Borders, where I concluded that Buffett will seek an opportunity to invest in a company that is paying a dividend and has a very easy to understand product or service that will not become obsolete any time soon.

"The technical backdrop has taken a distinctly bullish turn," says Michael Ashbaugh in MarketWatch's The Technical Indicator. Here, he looks at the market averages and a trio of stock ideas.

"Perhaps most obviously, the S&P has staged a 10-to-1 rally, and a 28-to-1 spike, from its 200-day moving average. And by any measure, this raises a bullish technical flag.

"With a gravity-defying rally, the S&P extended its gains, clearing resistance at 930 last Thursday. From current levels, significant resistance holds at the 2009 closing high of 946 while initial support rests at 930.

"Meanwhile, the Dow's near-term view is similar. With this week's rally, it's staged a 'V'-shaped reversal, breaking to one-month highs. Looking ahead, significant resistance holds at 8,799 - matching the 2009 closing high - while support rests at 8,580, matching the breakout point.

"The steel stocks tend to go through boom and bust cycles depending on global economic activity; they have been pummeled over the last year, as the global economy slowed," notes turnaround expert George Putnam.

In his The Turnaround Letter, he explains, "But the news about steel is not all bad." Indeed, he believes some steel companies are poised for a turnaround. Here's his review of 6 leading steel production companies.

"Weakness in two big steel consuming industries, autos and construction, has been particularly troublesome for the steelmakers.

"However, there is evidence that steel inventories are gradually being worked off to low levels. There are also signs that economic activity in China, which is a huge consumer of steel, will not fall off as far as some economists initially feared.

Eoin Treacy of Fullermoney says that as commodities prices weaken, you need to look carefully before investing.

Q. Eoin, I've read that China's annual consumption of copper has declined from a 28.66% growth rate to 2.4%. What does that mean for continued growth in China and also for the global copper market?

A. China and indeed much of Asia and the Middle East are in a generational-long period where they have to build infrastructure from the ground up. The push for educating, housing, transporting and employing large young populations requires massive investment, fueling demand for commodities across the boards.

The supply side was completely taken unawares by this demand following the 20-year crushing bear market that cut exploration budgets to the bone. That is now changing, as major mining groups compete for the best resources, particularly in politically stable parts of the world.

China continues to lead the world in terms of GDP growth, although it has recently manufactured a slowdown to combat rising inflation, generally positive for the economy.

Back on August 16, with the Dow opening under 13,000 for the first time since April, our BloggingStocks experts outlined a number of stock plays to ride out this volatile market. Picks ranged from Dow components and other household names to obscure business-to-business giants and foreign market leaders. Here, we review our picks weekly.

In the seventh week since our Volatile Markets stock recommendations, only a few of our picks have seen significant movement.

After stalling last week, South Korean steelmaker Posco (NYSE: PKX), has jumped another $7.39. The 4.08% gain brings Peter Cohan's tip to $188.52, 52.02% higher than its August 16 opening price of $124.01.



Sheldon Liber's recommendation, Huaneng Power International Inc. (NYSE: HNP), gave back some of last week's 18.08% gain this week. Despite the Chinese utility's 6.53% knock, Huaneng still stands a formidable 30.40% higher since our volatile markets feature ran.

With the dollar hitting record lows every day, how can you make money in stocks? The short answer is to invest in growing companies based outside the U.S.

This strategy has propelled my investment newsletter to outperform the S&P 500 in the first nine months of 2007. Specifically, stocks highlighted in The Cohan Letter -- I highlight three stocks per month -- are up an average of 17%, compared to a 7% rise in the S&P 500 since the beginning of the year. Which three picks have done the best?·

• Posco (NYSE: PKX) rose 48% from $92.70 to $178.77. Barry Summerlin highlighted this Korean steel company, which I suggested might do well in an August post -- it's up 46% since then;
• CVRD (NYSE: RIO) -- the Latin American telecommunications mining company -- rose 45% from $18.50 to $33.85; and
• New Oriental Education and Technology Group (NYSE: EDU) -- a Chinese educational testing company -- rose 34% from $43.75 to $65.66.

I don't know whether these particular stocks have peaked, but if the dollar keeps dropping, they could continue to do well.

Peter Cohan is president of Peter S. Cohan & Associates. He also teaches management at Babson College and edits The Cohan Letter. He has no financial interest in the securities mentioned.

Week six was rough for a couple of our stock picks -- chiefly Target Corp. (NYSE: TGT) -- but Huaneng Power International Inc. (NYSE: HNP) just had a phenomenal week. Read on.

Posco (NYSE: PKX)'s gains have tapered a bit -- Peter Cohan's pick followed up last week's 10.41% run with a modest 1.30% rise this week. Still, just six weeks since our Volatile Markets feature, the South Korean steelmaker stands 46.06% higher! Incredible.



This week's big story, however, is Huaneng Power International Inc. (NYSE: HNP), recommended by Sheldon Liber. The Chinese utility nearly doubled its gains as of last week, shooting 18.08% higher, closing Thursday up 39.51% in the last six weeks!

Ben Bernanke's buyout bailout is helping push the dollar to record lows. While this will make your travel outside the U.S. shockingly expensive, the Washington Post offers some ways you can invest to ease some of that pain:

• Buy foreign stocks. The U.S. investor converts dollars into the currency needed to buy the stocks, whether euros, pounds, yen or something else. Then, if the share price holds and the dollar falls, the investor gains when he sells the stock and converts the money back into dollars. If the share price has risen, the profit is even greater. Of course, if the dollar appreciates in the interim, the process works in reverse. As Barry Summerlin notes, my recommendation of Posco (NYSE: PKX) has gone up significantly since August, probably due in part to this effect.
• Buy U.S. companies with overseas earnings. buy the stocks of big, multinational U.S. companies that benefit from the weaker currency. A lower dollar helps boost U.S. exports by making them relatively cheap on world markets The Boeing Company (NYSE: BA) is among the beneficiaries of this trend.
• Buy CDs, mutual funds and exchange-traded funds packed with various currencies or linked to baskets of foreign exchange. More than $2.7 billion was invested in open-end currency funds by the end of July, up from $36 million at the end of July 2000, according to estimates by Lipper. So far, the falling dollar fund is the better bet: It is up 7.91% for the year, as of Thursday. The rising dollar fund is down 2.66%.

Wow! I hope you looked into Peter Cohan's pick, Posco (NYSE: PKX), when our feature ran. Like a broken record, again I ask how long the South Korean steelmaker can continue these fantastic gains -- 44.37% higher in just five weeks! Even if you bought in last week, you'd already be up 10.41%. Phenomenal.



Also performing handily are two of Sheldon Liber's picks, Huaneng Power International Inc. (NYSE: HNP) and Anadarko Petroleum (NYSE: APC). China's Huaneng rose 1 1/2% since last week to close at $44.99 Thursday, putting it up 18.43% since our virtual purchase August 16. Texas energy concern Anadarko has gushed 4.48% higher since last Thursday, climbing to $52.96, a total gain of 11.54% since our August 16 Volatile Markets feature.

Four weeks into our Stocks for a Volatile Market feature, our index has fallen just behind the Nasdaq, grounded mostly by shoe and apparel maker Steven Madden (NASDAQ: SHOO), picked by Kevin Kelly. After giving up $2.51 in week three, Madden dropped $3.39 in week four, falling 14.7% and leaving SHOO at $19.67, 17.77% under its August 16 price of $23.92.

Might as well get all the bad news out of the way -- it looks like Sheldon Liber's call, FreightCar America Inc. (NYSE: RAIL), has temporarily derailed. After strong gains in previous weeks, RAIL dropped $3.78 in week four -- a loss of 8.35% -- and slipped to $41.49, 4.4% under its initial price.
