Hello Readers,

The new year is off to a decent start for the markets, thanks to an 11th-hour tax deal where the congressional Republicans caved. Some of their reasoning was fear that the markets would see a huge sell off, if they failed to act. Who would have cared about the sell off? Markets go up and markets go down. If they had tackled the spending issues right then, when they had some great leverage, they probably would have gotten much of the spending cuts they wanted, and the markets would be on a major tear, right now. So, what do they do? They drag the nonsense out even more. Does the GOP really think that they will get any real spending cuts, now that they trashed their real leverage? Oh sure, they think the debt ceiling clock is on their side, but that strategy failed in the mid-nineties and we suspect it will fail, again.

We have not yet closed any positions so far this year, but pockets of our Current Portfolio have seen improvement. A lot of our future, and that of the market, may be at Washington’s mercy. That’s the bad news. The good news, if you can call it that, is that the Fed is now pumping around $85 billion more liquidity into the financial markets each month.

Here are the headlines since the last Newsletter about companies in the Current Portfolio; dates in parentheses are when we first recommended them. We are not giving updates about companies on the “Endangered List” unless we feel the news to be highly significant.

Our picks for this Newsletter are a biofuels maker and a player in the fight against obesity, both NASDAQ-listed.

GEVO, INC. (NASDAQ: GEVO) – $1.90. Twelve-month hi-low has been $11.29 – $1.36. Located in Englewood, CO, with about 110 employees, this biofuels maker, has 39.4 million shares outstanding, $98.25 million in total current assets, $178.36 million in total assets, and $68.47 million in total liabilities, of which $45.35 million is long-term debt. Institutional ownership is around 85%. Four analysts rate the stock a “strong buy” and three as a “buy”. www.gevo.com

Sometimes we pick a stock for kicks and giggles and Gevo, Inc. is one of them. To be blunt, it is one of those Al Gore- type companies that we have been burned on over the years. Having said that, the company, after a long rough patch, does have some nice cash reserves, strong institutional ownership, and over a half-dozen analysts lined up behind it.

Founded in 2005, and public for just less than two years, Gevo bills itself as a renewable chemicals and advanced biofuels company, focusing on the development of alternatives to petroleum-based products based on isobutanol produced from renewable feedstocks. The company is converting existing ethanol plants into biorefineries to make renewable building block products for the chemical and fuel industries. It plans to convert renewable raw materials into isobutanol and renewable hydrocarbons that can be directly integrated on a “drop in” basis into existing chemical and fuel products to hopefully deliver environmental and economic benefits. Gevo calls this process Gevo Integrated Fermentation Technology and has a development agreement with BioFuel Energy Corporation for production of isobutenol.

One of the main drags on the stock price was a lawsuit with Butamax Advanced Biofuels involving yeast engineered to produce isobutanol. At the end of November, 2012, a Federal Appeals Court made a ruling that strengthened Gevo’s position in the patent dispute with Butamax. This was the second judicial decision supporting Gevo’s patents. The company has been issued thirteen patents with rights to over 450 patents and patent applications.

For FY2011, ending 12/30/11, revenue was $64.54 million with $48.22 million in losses. During the first nine month of FY2012, ending 9/30/12, revenue was $19.9 million with $47.54 million in losses. The drop in revenue over the last year reflects the company’s transition process.

This is a company in flux, but, for the reasons stated above, such as the seven analysts behind the company, it may be worth a shot.

Our 24-month target for the stock is $3.50 to $3.75.

ENTEROMEDICS, INC. (NASDAQ: ETRM) – $2.47. Located in St. Paul, MN, with about 30 employees, this medical device maker has 41.7 million shares outstanding, $29.63 million in total current assets, $30.72 million in total assets, little debt and $13.91 million in total liabilities. Institutional ownership is around 70%. One analyst rates the stock a “strong buy” and three analysts have it as a “buy”. www.enteromedics.com

Sometimes we come across a company that has a nifty story and, with its anti-obesity technology, EnteroMedics, Inc. seems like a good fit in our Current Portfolio. It also helps that they have a decent balance sheet to help them get to where they need to go.

Founded in 2002, and trading on NASDAQ for over five years, EnteroMedics is developing medical devices that use neuroblocking technology to treat obesity, metabolic diseases, and other gastrointestinal disorders. Its proprietary neuroblocking technology, the VBLOC vagal blocking therapy, is designed to intermittently block the vagus nerve using electrical impulses. These are delivered by a pacemaker-like device called the Maestro Rechargeable System, which is designed to control both hunger and fullness by blocking the primary nerve which regulates the digestive system. It is intended to limit the stomach’s expansion, control hunger sensations between meals, reduce the frequency and intensity of stomach contractions, and produce a feeling of early and prolonged fullness.

EnteroMedics is evaluating the Maestro System in human clinical trials in the U.S., Australia, Mexico, Norway, and Switzerland. It has collaborations with the Mayo Clinic and the Australian Institute of Weight Control for R&D of its products. Maestro has received the CE mark in Europe for treating obesity, and has been listed on the Australian Register of Therapeutic Goods (ARTG).

This is another small R&D company with limited revenues and hefty losses, for example, during the quarter ending 9/30/12, revenue was zilch with losses of $5.85 million.

We like the technology and its tie-in to the Mayo Clinic, the number of analysts behind the stock, and the institutional ownership isn’t too shabby.

Our 24-month target for the stock is $4.00 to $4.50.

Look for the February 5, 2013 Newsletter to be posted on 2/1 or 2/4.
