TheStreet.com's Jim Cramer says there's a big disconnect between the trade, orchestrated by the funds, and the real-world demand.

How can anyone actually own oil or natural gas through this relentless assault on price? I know when it was going up, the talk was that all of these new funds were indexing trillions to commodities and it was just going to stay there, and that's why there was a new level of oil demand.

Can those same accounts come in every day and take this relentless pasting no matter what the news? And do they believe the news, that they are losing money today because some storm went to Daytona and not to New Orleans?

Yesterday, I had Jim Hackett, the CEO of Anadarko Pete (NYSE: APC) (Cramer's Take) on "Mad Money at the Half," and he was flabbergasted at the activity in the futures pit and how unrealistic it has become. He's focused on natural gas, where he says the demand at $8 by industry -- the glass makers and chemical companies and steel and aluminum users -- is voracious. But the futures themselves just keep going down, regardless of the demand.

TheStreet.com's Jim Cramer says the value creation at both companies is astonishing and not going away, despite the market trend.

Every now and then days like yesterday happen. Days where it is so crazy, where the selling never ends and the buying never ends. Where the sellers just keep reloading and the buyer just keep buying.

Some of it seems like short-covering panic and some of it seems like sellers who can't take the pain anymore. As I watched Cabot Oil & Gas (NYSE: COG) (Cramer's Take) -- a very good company, a company that priced a gigantic piece of merchandise 30% higher a fortnight ago -- go down more than 10% today, I am astonished at the market's inefficiency.

When I see Nucor (NYSE: NUE) (Cramer's Take) decline 10% on a good quarter and conservative guidance, I marvel at how ridiculous things are. Sure, you can say if you look at a three-year chart, "This is the end of the bubble." But how about value? How about the fact that COG is making much more money than it ever has and is unlikely, given the big shift toward natural gas, ever to make as little money as it did a few years ago?

MOST NOTEWORTHY: WebEx Communications, Inc (WEBX), Avaya Inc (AV), Tractor Supply Co (TSCO), Nokia (NOK) and Mattel, Inc (MAT) were some of today's noteworthy downgrades:

• Wachovia downgraded shares of WebEx Communications Inc (NASDAQ: WEBX) to Market Perform from Outperform to reflect the company's pending acquisition by Cisco Systems (CSCO).
• Bank of America cut Avaya Inc (NYSE: AV) to Neutral from Buy with a $13 target after taking in account the company's acquisition of Ubiquity Software Corp Plc. The firm believes sales may miss consensus for the next few quarters, while gross operating margins could disappoint.
• CIBC downgraded Tractor Supply Co (NASDAQ: TSCO) to Sector Performer from Sector Outperformer. The firm sees some moderate upside for shares of TSCO but says it will be incrementally more difficult to achieve without a major fundamental driver in the near-term.
• WestLB AG downgraded shares of Nokia (NYSE: NOK) to Reduce from Hold.
• Mattel Inc (NYSE: MAT) was cut to Market Perform from Outperform at BMO Capital on valuation.

OTHER DOWNGRADES:

• First Albany downgraded Cerner Corp (NASDAQ: CERN) to Neutral from Buy.
• Keefe Bruyette downgraded A.G. Edwards, Inc (NYSE: AGE) to Market Perform from Outperform on valuation.
• Rodman & Renshaw downgraded shares of Genentech, Inc (NYSE: DNA) to Market Perform from Outperform citing a slowdown in near-term growth and valuation that reflects most of its future growth.
