TheStreet.com's Jim Cramer says recent downgrades are killing whole industries, and they're coming at a terrible time.

You can't lose autos and aerospace. Yet that's what's happening. The devastating aerospace downgrade by Goldman yesterday had pin action galore, wrecking everything from United Tech (NYSE: UTX) (Cramer's Take) and Parker-Hannifin (NYSE: PH) (Cramer's Take) to BE Aerospace (NASDAQ: BEAV) (Cramer's Take). It took the whole frame down with it and made everything toxic. And it happens at a terrible time. It isn't like Honeywell (NYSE: HON) (Cramer's Take), which with a few days left in the quarter can come out defending itself. Goldman rolled a perfect strike.

And now the bowlers are back for more with an equally devastating "sell everything" call based on GM (NYSE: GM) (Cramer's Take). Once again it is seamless: Lear (NYSE: LEA) (Cramer's Take) and Tenneco (NYSE: TEN) (Cramer's Take) get jettisoned too, but you know that Visteon (NYSE: VC) (Cramer's Take) and American Axle (NYSE: AXL) (Cramer's Take) and Johnson Controls (NYSE: JCI) (Cramer's Take) and BorgWarner (NYSE: BWA) (Cramer's Take) -- the good ones! -- go down with the car.

MOST NOTEWORTHY: Mueller Water, ASM International and Kensey Nash were today's noteworthy upgrades:

• Jefferies upgraded shares of ASM International (NASDAQ: ASMI) to Buy from Hold as they believe a break-up is likely following bids for the company's front-end business.
  
• Susquehanna said Kensey Nash's (NASDAQ: KNSY) sale of its endovascular products division was the best outcome and will allow the company to focus on being a pure-play OEM biomaterials platform company. Shares were upgraded to Positive from Neutral.

MOST NOTEWORTHY: RF Micro Devices, Western Digital and Boyd Gaming were today's noteworthy downgrades:

On tonight's Mad Money, Jim Cramer noted Borg Warner Inc. (NYSE: BWA) as a company that can actually win on the "green movement." This is an auto parts and power trains applications company, certainly not something that would normally be thought of as a "green investment." But the company is working on developing more environmentally friendly products, and currently has a $1.7 billion backlog and the orders are still accelerating. Before you follow Cramer blindly, you should know that this may be true that the company has "lower emission" parts than others, but it looks like he is out picking the auto parts players that are still standing and close to highs more than a true "green investment" pick.

Once again, there are safer ways (safe being relative to diversification only) to play alternative energy ("alt-en"). A few names I have looked at for exposure to alternative energy and that I feel better about are actually what I call the "alt-en" ETFs, and these may offer you a safer mix of companies since some of the holdings are diversified and have many different operations. The PowerShares WilderHill Clean Energy ETF (AMEX: PBW), PowerShares Cleantech ETF (AMEX: PZD), and PowerShares WilderHill Progressive Energy Portfolio (AMEX: PUW) will all give some alternative-energy sector exposure that won't as easily rip apart your wallet if you make the wrong pick. ETFs will not give you the upside potential of a single speculative play, but if you've been doing this long enough, you already know how painful picking the wrong name in the right sector can be. Alt-en ETFs give you exposure to the sector without the company-specific risk.
