Sector Commentary

Currencies:  The Japanese yen fell nearly 5.5% versus the U.S. dollar after the Bank of Japan reaffirmed its commitment to increasing its quantitative easing measures. The euro similarly fell after the European Central Bank indicated it might increase the use of stimulus initiatives to meet inflation targets.  The U.S. dollar strengthened on speculation monetary policy in the U.S. would continue to diverge from the policies of its global counterparts.

Energy:  Prices in the crude oil complex declined after OPEC decided to maintain current production levels despite the abundance of global supplies.  Natural gas markets rose due to forecasts for colder weather in the U.S.

Equities:  European and Asian equity markets rallied after central banks in the Eurozone, China and Japan individually announced plans to expand quantitative easing initiatives.  Upbeat German economic data added to gains in the European equity markets.  The U.S. markets rallied on bullish prospects for the upcoming holiday shopping season and on reduced oil prices.

Fixed Income:  U.S. Treasury markets rose as weak economic data, including employment and consumer spending data, moved U.S. debt markets higher.  Expectations the U.S. Federal Reserve will wait until 2015 to raise interest rates also supported higher Treasury prices.  The German Bund markets moved higher after the release of weaker than expected economic growth data and news Germany narrowly avoided falling into a recession in the third quarter.

Grains/Foods:  Wheat prices rose on concerns about output from Australia and Russia.  Corn markets finished modestly higher following an increase in ethanol production in the U.S.  Soybean prices fell due to improved harvesting conditions.  Coffee and sugar prices also fell as increased rain in Brazil eased drought-related supply concerns.

Metals:  Silver and platinum markets weakened in reaction to a stronger U.S. dollar.  Gold prices rose after China unexpectedly cut interest rates.  Copper markets finished lower following the release of weak Chinese manufacturing data and on liquidations by large commodity investors.  Copper was also pressured after a strike at a key Peruvian copper mine was settled.
