Despite the U.S. stock market's recent run up, the decline in the U.S. dollar and inflation fears have investors searching for safety in these uncertain times. A popular strategy that has emerged is to hedge market and currency risk with commodities, namely gold, oil, and uranium. What specific stocks and investments in these sectors are likely to outperform?

ETFs like the US Oil Fund (NYSE: USO) and the SPDR Gold Shares (NYSE: GLD) will obviously track any rise or fall in these commodities to a T, but perhaps individual companies in these sectors are a better fit for you. Below are some industry giants, as well as speculative plays that are also drawing attention from investors.

Brigham Exploration (NASDAQ: BEXP) explores for oil and gas across the Anadarko Basin, the Texas Gulf Coast, and West Texas. According to Hoover's, since its founding in 1990, the company has drilled more than 731 wells. Additionally, BEXP was one of the first small independent exploration/production concerns to utilize 3-D seismic imaging technology in its business.

On November 6, BEXP reported third-quarter earnings (before items) of 8 cents per share as revenue jumped 20% to $31.1 million. Analysts were expecting per-share results of 6 cents on $31 million in sales.

Since forming a bottom around the $4.20 level in early August, BEXP has shot solidly higher along the support of its 10-day and 20-day moving averages. This rally has additionally enabled the stock to muscle above its 20-month (200-day) moving average. In fact, the stock ended October above this trendline, the first such monthly close north of this threshold since December 2006.

MOST NOTEWORTHY: Air France, BHP Billiton, AstraZeneca, Broadcom and Savvis were today's noteworthy downgrades:

• Goldman removed shares of Air France (NYSE: AKH) from its Conviction Buy List due to the increase in the price of fuel and the possibility of an economic slowdown.
  
• Goldman downgraded BHP Billiton (NYSE: BHP) to Neutral from Buy and removed the stock from its Pan-Europe Buy List due to valuation.
  
• Merrill Lynch downgraded shares of AstraZeneca (NYSE: AZN) to Sell from Neutral to reflect increased competition from generic-drug makers, a poor pipeline and slow earnings growth.
  
• Wachovia downgraded shares of Broadcom Corporation (NASDAQ: BRCM) to Hold from Buy to reflect valuation and the company's lower than expected Q3 results. Shares were also lowered to Hold from Buy at Deutsche Bank.
  
• Stanford lowered Savvis (NASDAQ: SVVS) to Hold from Buy and notes that the company's Q3 results and Q4 revenue guidance brings the company's 2007 revenue outlook $15M below the consensus, and advises investors to remain on the sidelines. The firm believes the company's strategy is sound, but that its execution has been slow.
