Cramer on BloggingStocks: Copper inventory build threatens the cyclicals

We were simply waiting for two straight weeks of copper inventory builds over in London. That was the signal that China was kaput and you had to sell Chesapeake (NYSE: CHK) (Cramer's Take) and BHP Billiton (NYSE: BHP) (Cramer's Take)! Didn't get the memo.

And yet that's the universal one-minute takeaway of the Shanghai 7% plunge and will no doubt turn into another day of fruitful buying of Merck (NYSE: MRK) (Cramer's Take), Johnson & Johnson (NYSE: JNJ) (Cramer's Take), anything HMO and Express Scripts (NASDAQ: ESRX) (Cramer's Take), not to mention longtime Cramer faves Hershey (NYSE: HSY) (Cramer's Take) and Altria (NYSE: MO) (Cramer's Take).

How about tech?

China.

Could get hurt, too.

(There's also a story that Chinese banks are going to cut down lending, but that's a story that I have seen before, making the copper-LME story even more cogent.)

The binary nature of the market repulses us because 1) it has nothing to do with us, as we don't set the price of oil, China does -- unless of course we manipulate it -- and 2) we are a tenth of the world's copper use and they are a third of it.

So today, the gentle rolling correction as we work off the overbought oscillator continues, with the cyclical complex once again bearing the brunt of it.

Random musings: When I look at the quarters that were really ugly, they were the ones that had the most aerospace, not autos. Something looking up in autos or down in aero ... or, well, BOTH!
