Today was an ugly day for stocks but a great day for commodities.

One day after the Federal Reserve decided to leave interest rates alone, commodities surged. Oil rallied nearly $5 a barrel to reach a new all-time record of $139.64. Corn and soybeans also reached new highs. Gold jumped $32.80 to reach $915.10 an ounce.

But stocks moved in the opposite direction. The Dow plunged 358.41 points to close at its lowest level in 21 months. Goldman Sachs lowered General Motors to a Sell and the stock fell to its lowest level in 53 years. Shares of Citigroup fell to a 10-year low.

Resource stocks like Barrick Gold (ABX), Weatherford (WFT) and Cal-Maine Foods (CALM) were particularly strong today. One of my favorite Emerging Growth stocks, General Steel (GSI), defied the market and also closed higher.

In Quantum Growth, Starent Networks (STAR) was stopped out at $12.86 a share. If you're a Quantum subscriber and you still own Starent, I recommend you sell it as soon as you can.

The most painful stock today was Research In Motion (RIMM) which is a Blue Chip Growth recommendation. The shares dropped over 13% today. Yesterday, the company reported that its earnings more than doubled to 84 cents a share, but it was a penny below the Street's estimate. More troubling was that RIMM's guidance for Q2 was also slightly below what Wall Street was expecting. In Blue Chip, I rate RIMM a buy up to $151 a share.
