From the following trend score table, one can see the broadbase commodity index (DBC) actually had its trend score increased in last week. 

Assets Class	Symbols	03/18 Trend Score	03/11 Trend Score	Direction
Silver	SLV	40.11%	47.09%	v
Energy	DBE	16.53%	14.75%	^

Gold	GLD	8.86%	9.46%	v
Base Metals	DBB	6.53%	4.5%	^

The trend score is defined as the average of 1,4,13,26 and 52 week total returns (including dividend reinvested).

Amid the somewhat severe and volatile market correction last week, it is relevant to review several commodity themes again here: 

• Agriculture commodities (DBA): world food price has risen in the past several years and the demand from emerging middle classes outstripped the supply. See Commodities Trends: Food Prices Rose More Than Normal CPIs for more analysis. 
• Precious metals (gold, silver) (DBP): governments around the globe pumped money to stimulate the economy, let alone the quantitative easing 1-2 by the U.S. central bank would surely make paper currencies less valuable and thus precious metals (Gold and Silver) become the defacto hard currencies. We also pointed out that Silver plays dual roles (as a proxy to hard currency and a proxy to general industrial activities being a metal of practical use). 
• Energy (Oil (USO) or natural gas (UNG)) (DBE): Amid the middle east political unrests and recent Libyan's upheaval (Libya has the ninth largest oil reserve in the world), oil production is in danger of sudden disruption. 
• Broadbase commodities (DBC) (GSG): Along with the mentioned factors, recent natural disaster in Japan, the third largest economy in the world, will only add more government supported stimulus, commodity hoarding will only get worse. 

Though strong fundmentals are supporting commodity investing for now, we should point out that commodities are notorious volatile: geopolitical events and general economic activities (and expectation, such as inflation expection) can change the direction of commodities dramatically. It is thus important to properly allocate in one's portfolios and actively manage a portfolio's asset allocation.
