Minyanville's Sean Udall dares to share the kind of keen insight and actionable information you won't find in any prospectus. Here he answers a reader's burning question about "green" stocks. For more original thought, visit www.minyanville.com.

Professor Udall,

Do you have any opinions on Zoltek Companies, Inc. (NASDAQ: ZOLT)? My wife wants me to buy everything "green". Her last "green" company idea was General Electric (NYSE: GE). I know, right? I bought a little just to quiet the noise level. I'm into a little SunPower (NASDAQ: SPWR) and Evergreen Solar (NASDAQ: ESLR). Does Zoltek have legs?

Thanks,

Minyan L.

Minyan L.,

First, that's hysterical. Second, a word of caution: Going all green, or all of any one thing, is something I'd never advocate. If you do, you do so at your own risk, as nothing in the market is ever as obvious as it seems, especially when it seems totally obvious.

The earnings party of last week was full of fun and frolic. For the most part, if you followed my list of recommendations, you would have had your very own "Fiesta de Finance." (See Week in Preview – May 5)

The earnings season is still in full swing and should provide a great deal of action for the companies that will be reporting. But these companies will have to fight through a few new economic barriers. With oil pushing past historic levels and questions beginning to surface concerning the ability of the investor to continue to support a market that has so many headwinds, the mood is likely to shift moving forward. It is time for discipline, short and simple. Now, more than ever investors need a plan. I cover this strategy in my book, The Disciplined Investor.

In the last installment of The Week in Preview, I was looking for party opportunities in honor of Cinco de Mayo. This week, Misery is the theme. That is the only word that comes to mind with oil at a level that you would have never expected, a massive and unrelenting credit and housing crisis and a banking system that is defunct.

Monday - May 12

We start the week with a report from IndyMac Bancorp (NYSE: IMB). This bank is smack in the middle of the housing problem. It is primarily a lending company that facilitates loans for single-family homes. It's also involved in the origination and trading of mortgages. How does that sound to you as an investment? Shares have slid from $23 in October 2007 to an unbelievable level of $3.50 recently. Ouch... If you are a shareholder still holding on with hope and a prayer for something...anything, keep on dreaming. The good news is that the stock is sporting a yield of 29%. But, if you think that yield is going to be maintained, I have a bridge for sale. Estimates are for a loss of $1.92 per share for the quarter.

Zoltek Companies Inc. (NASDAQ: ZOLT) stock is down big this morning after the company posted a first-quarter profit of 8 cents per share, well below analysts' estimates of 24 cents per share. ZOLT's CEO blamed inventory buildup, which is probably due to the sagging economy. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on ZOLT.

After hitting a one-year high of $51.77 in August, the stock has hit a new one-year low today. This morning, ZOLT opened at $27.28. So far today the stock has hit a low of $26.16 and a high of $28.08. As of 11:15, ZOLT is trading at $27.64, down $4.99 (-15.3%). The chart for ZOLT looks bearish and steady.

For a bearish hedged play on this stock, I would consider a June bear-call credit spread above the $40 range. A bear-call credit spread is an options position that combines the purchase and sale of call options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. This particular trade will make a 6.4% return in four and a half months as long as ZOLT is below $40 at June expiration. Zoltek would have to rise by more than 42% before we would start to lose money.

ZOLT hasn't been above $40 since early January and has shown resistance around $35 recently. This trade could be risky if the stock bounces back from today's drop, but even if that happens, this position could be protected by resistance ZOLT might find at its 200 day moving average, which is currently around $40 and falling.

"Alternative energies are not just a pie-in-the-sky dream," says Paul Tracy and Nathan Slaughter from the StreetAuthority Market Advisor. "Denmark generates as much as 30% of its power from wind, Iceland uses geothermal energy, and producers are bringing down the cost of solar power."

"Overall, companies involved in alternative power technologies, such as wind, solar, geothermal, and biomass, are getting plenty of attention from investors these days." Here, the advisors profile what they consider to the most attractive companies in the alternative energy space.

Suntech Power Holdings Co. (NYSE: STP), "which manufactures and sells photovoltaic (PV) solar cells, has two primary advantages: a low manufacturing cost base and highly efficient cells.

"For starters, Suntech is based in China, where labor costs (even for skilled research staff) are far lower than in the Western world. The Chinese government also subsidizes such research, further helping companies like Suntech.

"In addition, the firm's cells boast some of the highest conversion rates on the market, allowing the company to offer smaller panels that can produce as much electricity as far larger ones from competitors.

"Suntech has been ramping up its manufacturing capacity rapidly in recent years to keep pace with strong demand. Analysts are forecasting robust earnings growth of 45% annually over the next five years.

Carbon fiber manufacturer Zoltek Companies Inc. (NASDAQ: ZOLT) can no longer be considered a startup, as evidenced by the company's recent decision to sell 4,000,000 shares of stock to the general public at $38.76 per share. Some of these shares originally belonged to senior management who now have the right to sell the shares and collect their due after years of nurturing the company into profitability. The stock closed Tuesday at $37.60, down $2.15, but Zoltek makes much in-demand products like carbon fibers and other technical fibers, which are essential components in various technology components. The market will very soon catch up to the sale price. Tech investors will want to take a look at Zoltek in the near future.

The company reported third quarter 2007 on Aug 6. Net sales increased 50% to $40.3 million. Operating income was up 72% to $6.7 million and net income was $5 million or $0.17 per diluted share. This is certainly an improvement over a $21 million loss in 3Q 2006.

Zoltek is turning an important corner in which income from continuing operations no longer must be plowed straight back into expanding the business. Zoltek has grown its production capacity significantly, and recently signed a five-year , $142 million contract with a Spanish firm to provide carbon fibers for wind turbine generators. The company has reduced its long-term debt significantly, but has increased its short-term debt by a similar amount. Investors who enjoy a ride now and then may find Zoltek's public stock offering of interest.

In my book about Baby Boomer investing I highlight what I feel are the five major growth industries going forward. The industries are health care, alternative energy, technology, communications and lifestyle. I also mention 42 companies within those industries that could be the leaders, the game changers. Since the book has been published, five of the 42 stocks I wrote about are being acquired!

The latest one to go is Checkfree (NASDAQ: CKFR). Fiserve (NASDAQ: FISV) has announced its $4.4 billion bid. Checkfree made our banking-transactional life much easier. The other four that will be part of larger companies are Opsware (NASDAQ: OPSW), Color Kinetics (NASDAQ: CLRK), aQuantive (NASDAQ: AQNT) and Kyphon (NASDAQ: KYPH). Other than aQuantive, the other three were also part of my Top 25 stocks for the NEXT 25 years series.

As the 42 companies are down to 37, it causes some reflection for the future. Great, emerging companies will always be on the radar screen of larger, well-financed suitors. If growth cannot be internally generated through research and development efforts, larger companies will need to acquire growth and next generation products or technology. With interest rates still historically low, the borrowing necessary to buy these young, up-and-comers is not a significant issue. Investors will reward mature companies if they acquire intelligently and strategically.

In my series of the top 25 stocks for the NEXT 25 years I promised you that if anything relevant or game-changing were to come about, I would write it up for your reading pleasure. Well, I have some new news on Zoltek Co. (NASDAQ: ZOLT). I wrote up the initial Zoltek report just last week, but since that publishing, some relevant good news has come up.

Zoltek is the worldwide leader in the manufacturing of carbon fiber material. Carbon fiber has hundreds of applications from sporting goods to aeronautical casings. The most popular application of carbon fiber is as the material of choice for rotor blades on huge energy-generating wind turbines. The carbon fiber is lighter, less prone to friction and therefore far more efficient and cheaper to operate than traditional materials. The Dewind Corporation (a subsidiary of Composite Technology Corp./OTC: CPTC) has contracted Zoltek for the next several years to supply it with enough carbon fiber material to satisfy its growing demand.

This comes on top of the commitment made to Zoltek by the large Danish wind generator company Vestas. Vestas is one of the leading European companies in the energy field and known for its cutting-edge choices in technology and materials.

World leader in carbon fiber manufacturing, Zoltek Companies Inc. (Nasdaq: ZOLT) reported strong 2Q 2007 earnings [pdf] on May 4. Net sales increased 40% to $36.7 million. Operating income increased a whopping 87% to $5.9 million, and the company reported a $3 million increase in cash flow compared to the same quarter last year. Zoltek is on a tear, with this quarter's sales increasing 21% from last quarter's sales. The combination of 1Q + 2Q shows net sales increasing by 60% to $67 million, with operating income increasing from $1.4 million to $8.1 million. Zoltek has made tremendous strides in controlling costs and returning to profitability. 2Q 2007 net loss was breakeven per share compared to 2Q 2006 net loss of $27.7 million, or $1.31 per share.

Zoltek is looking forward and planning for much future growth. Two new production facilities in Hungary come into operation in 2Q 2007, with two more new production facilities scheduled to come into operation in 3Q and 4Q 2007. Thus Zoltek will be able to increase productivity at the same time as prices are continuing to increase, generally a happy situation for investors. The increased production capacity will come in handy as Zoltek just negotiated a deal with Vestas Wind Systems to supply $300 million worth of fiber materials over the next 5 years. Zoltek is scheduled to ramp up to annual production of more than 10,000 metric tons of carbon fiber by 2008, compared to 2,800 metric tons annual production currently.

This stock is thinly traded and thinly followed, but may repay investors willing to dig around doing their own due diligence. The stock closed at $35.94 recently, down $0.34.

"At first glance, the upcoming Airbus A380 and the Boeing 787 Dreamliner planes look much like existing commercial models – but nothing could be further from the truth," says energy and resource industry expert Elliott Gue.

In Personal Finance, the editor notes, "Both are 20% to 30% more fuel efficient than any planes currently flying, due largely to lightweight composite materials."

Composites, he notes, are formed from two dissimilar materials -- usually a reinforcing fiber and an adhesive epoxy or resin, with carbon-fiber composite being the most commonly used in aircraft construction.

And it's not just airplanes that use these advanced materials; Gue observes, "Wind-power blades, oil rigs and sporting equipment all use high-strength, space-age materials. That spells soaring demand and solid growth for a handful of companies involved in their manufacture."

For those looking to invest in the "composite" industry, the advisor offers a trio of ideas. First is Hexcel (NYSE: HXL), the world's largest producer of "prepregs" for the aerospace industry. Prepregs, he explains, are woven carbon-fiber sheets that when chilled remain flexible and can be bent to shape or pressed into molds.

Gue says, "Outside aerospace, the wind power industry is fast becoming Hexcel's most important source of revenues. In fact, wind power is the company's fastest-growing major source of revenue; Hexcel projects at least mid-teens growth from that line this year.
