NEW YORK (TheStreet) -- This week, the attention of most market participants will be on what action Congress takes in their sole week of session for the month of November. The most important item facing Congress is the looming expiration of the Bush tax cuts.

Some progress is likely this week with both parties facing a backlash if no action is taken and all tax rates revert to higher levels. We believe this week will set the stage for Congress to pass a one or two-year extension of all the Bush tax cuts, but -- as we noted last week -- it is a close call.

The uncertainty over the fate of the tax cuts, along with faster-than-expected inflation in China, stoking fears of a rate hike, and the ongoing debt problems in the eurozone, contributed to volatility last week. Stocks, as measured by the

S&P 500

, gave back 2.1% after gaining 3.6% in the prior week. Last week also saw two markets that lately have been immune to these considerations demonstrate higher volatility:

Gold prices fell 1.8% after gaining 2.5% the week before (according to Bloomberg data).

Emerging market stocks, measured by the MSCI Emerging Markets index, were down 3.0% after being up 4.6% in the prior week.

The return of volatility to gold and emerging market stock prices has raised a question among some market participants: is the relentless climb pushing gold and emerging market stock prices into bubble territory? We do not think so. If they are bubbles, historically they still have a long way to inflate before they burst.

Gold Prices

As you can see in Chart 1, gold prices have tracked the classic bubble pattern but have yet to enter the parabolic stage where the bursting of the bubble and the ensuing sharp losses begin to become a risk. The investment bubbles of the past experienced far more inflating than what gold prices have experienced so far. The technology bubble of the 1990s (measured by the

), the oil bubble of the late 1990s/early 2000s (measured by oil futures prices), and the housing bubble (measured by the S&P 500 Homebuilders Index) took 10 years and posted gains of about 1000% before they burst and quickly surrendered most of those gains.

What could push gold prices into historical bubble territory? While rising central bank demand, higher mining costs, and demand for gold as a luxury and a savings vehicle from a rising middle class in China and India all help to support gold, the potential driver of a bubble would likely be driven by currency. Part of the rise in gold is due to the decline in the value of the dollar. As the dollar goes down the price of gold in dollars goes up. While gold has surged to an all time high over the past five months in dollar terms, gold denominated in euros remains below the levels reached five months ago.

The move to record highs in the price of gold is more because we measure it in terms of a weakening U.S. dollar. A sharp drop in the dollar would boost gold prices in dollar terms and may also result in upward pressure on interest rates and slow economic growth boosting demand for gold as a perceived safe haven. While we expect the

Federal Reserve

's program of stimulus will continue to weaken the dollar well into 2011, we do not expect a sudden devaluation that would propel gold sharply higher.

Emerging Markets

Emerging markets suffered during the financial crisis of 2008-2009 when they experienced similar losses to developed markets. However, emerging market stocks have rebounded to prior peaks stoking fears of overvalued markets due for another sharp downturn. As you can see in Chart 2, emerging market stocks have not yet entered the parabolic stage where the bursting of the bubble historically becomes a risk.

What could push emerging market stocks into historical bubble territory? A flood of money has been pouring out of slow-growing developed economies into rapidly growing emerging market economies. As a result, the currencies of emerging market nations have been rising raising the risk of their exports becoming less competitive in world markets. As emerging market countries succumb to increasing pressure to reduce the strength of their currencies asset bubbles may inflate due to the excessive stimulus from domestic actions in addition to inflows from abroad.


While not in historical bubble territory, gold prices and emerging markets do have risks. For example, a contraction in growth in the emerging markets would weigh on both asset classes. And, importantly, if gold and emerging market stocks continue to track the bubble pattern, they have reached the stage of the pattern where volatility picks up and sudden, sharp moves become more common as the bubbles inflate and risks build.
