Hello Readers,

We did not close any positions since the last Newsletter. Our Current Portfolio is feeling the effects of the recent market slaughter, particularly in the NASDAQ and Russell 2000 averages. Of course, the big bugaboos are nose-bleed oil and gasoline prices, and now rising interest rates are gaining more attention than they had been. The Fed is still following the previous chairman’s mind set, which is to raise rates in hopes of calming inflation. Doesn’t raising rates only fuel inflation, since this expense will also be factored into costs, which, in turn, leads to higher prices? A major key for the markets between now and the Fall is what the Fed does at its June meeting. It may not be pretty. Now, after having sounded like the Grim Reaper, the markets all too often take off during the darkest moments.

Our picks for this Newsletter are a NASDAQ-listed tech company and an AMEX listed biofuels play, of sorts.

iCAD, INC. (NASDAQ: ICAD) – $1.67. Twelve-month hi-low has been $4.51 – $1.01. Based in Nashua, NH, with about 85 employees, this small tech has 36.9 million shares outstanding, $9.41 million in total current assets, $59.39 million in total assets ($43.5 million is goodwill), and $8.3 million in total liabilities. Institutional ownership is around 5%. http://www.icadmed.com

Normally, we would like to see a better-looking balance sheet; one with more cash and less goodwill. However, iCAD, Inc. has had some recent developments that could get it back on track.

Founded in 1984, and public for over a dozen years, ICAD bills itself as an industry-leading provider of computer aided detection (CAD) products for the early detection of breast cancer and other medical diagnostics. The company claims to be the only independent, integrated CAD software and digitizer company. At the end of 2003, iCAD merged with and acquired CADx Systems and its parent company Qualia Computing, bringing together two of the three companies approved by the FDA to market CAD systems for breast cancer detection. ICAD states that its mammography CAD systems are able to detect up to 68% of actionable missed breast cancers an average of 15 months earlier than screening mammography alone.

The company’s CAD systems include software technology coupled with standard computer and display equipment. iCAD systems for the film-based mammography market also include a radiographic film digitizer that it manufactures. These “gateway to digital” programs are suppose to make the transition to digital CAD mammography easier for breast care facilities currently using film-based solutions. ICAD’s platform solution, The TotalLook, is a comprehensive film-to-digital offering that converts prior films to digital images. The company also makes medical film digitizers for a variety of medical imaging and other applications.

Last month, ICAD hired a new CEO and a Senior VP of Sales, plus a marketing VP earlier this month. Also, iCAD was awarded contracts from HealthTrust Purchasing Group and MedAssets Supply Chain Systems for its SecondLook CAD systems. In March, Siemens Medical Solutions agreed to become a distributor for ICAD’s CAD systems. Of particular note, at the end of April, a dark cloud was lifted when the company won a patent arbitration that stated an infringement claim was completely without merit.

For FY2005, ending 12/31/05, revenue was $19.77 million with $4.88 million in losses. During the 1stQT of FY2006, ending 3/31/06, revenue was $4.37 million with $1.67 million in losses. The company attributes the dismal first quarter to distractions caused by merger discussions with its principal competitor. However, in February, iCAD terminated these talks.

Obviously, iCAD hit a few bumps, but recent contracts and new executive hires show promise for the future.

Our 24-month target for the stock is $3.00 to $3.25.

O2DIESEL CORPORATION (AMEX: OTD) – $1.33. Twelve-month hi-low has been $2.97 – 37 cents. Located in Newark, DE, with about 20 employees, this alternative fuel company has 46.4 million shares outstanding, $5.53 million in total current assets, $5.73 million in total assets, little debt, and $1.72 million in total liabilities. Institutional ownership is negligible. One analyst rates the stock a “moderate buy”.http://www.o2diesel.com

Admittedly, chasing “fad companies” makes us nervous, but the oil “crisis” created mainly by energy traders doesn’t seem to be abating anytime, soon, so why not take a shot with O2Diesel Corporation. It also helps that they recently raised another $6.5 million in funding, which is not reflected on the current balance sheet.

Founded in 2000, and public since 2003, O2 Diesel is a development-stage company that is developing what it calls a revolutionary clean-burning diesel fuel alternative. The company offers a fuel additive product, O2D05, that it claims enables distillate liquid transportation fuels to burn cleaner by facilitating the addition of ethanol as an oxygenate to these fuels. The O2D05 is supposed to stabilize and enhance blending of fuel grade ethanol with diesel fuel. This fuel additive can be made from soybean oil, other vegetable oils, or animal fats.

Commercial introduction of O2D05 is now underway in Texas, California, and the Northeastern U.S. Customers include urban truck and delivery fleets, municipal transits, railroads, and some local and state governments. Other countries where OTD is focusing are Canada and Brazil, where it has a 75%-owned subsidiary O2Diesel Quimico’s, Ltd; as we all know, Brazil is probably light years ahead of the rest of the world when it comes to biofuels.

Since OTD is still transitioning from the R&D to the P&L stage, revenues are scant while losses are huge. For FY2005, ending 12/31/05, revenue was $196,000 with $6.85 million in losses. Revenues in 2004 and 2003 were $127,000 and $12,000, respectively.

Ethanol, biofuels, etc have become the new buzz words in the energy quagmire. OTD’s stock could make a nice run if oil starts shooting toward $100 bbl. Also, it helps that the company just raised $6.5 million.

Our 24-month target for the stock is $2.25 to $2.50.

Look for the June 5, 2006 Newsletter to appear on May 31 or June 1.

Have a safe holiday,
