Dividends and commissions are ignored in performance calculations. The model theoretical performance noted above includes performance history of the model account prior to the establishment of the firm while Jim Oberweis was employed at other firms. The theoretical performance contains many high beta growth stocks which tend to be more volatile than DJIA stocks. The theoretical performance of the model does not represent actual trading and does not reflect the impact that material economic and market factors might have had if actual client money were managed. Tax consequences must be carefully considered. Changes in our theoretical portfolio and current quote prices are made as of the last Friday of each month. (This issue as of close of 6/29/2012) The Risks of "RISK ON!" and "RISK OFF!" It could be a great drinking game. Every time someone utters the phrases “risk on” or “risk off” on CNBC, you take a swig. These days, you would be trashed before you’re done with your first cup of morning coffee. It’s a trader-driven mentality on today’s Wall Street, and nothing provides more comic relief in the office than hearing these two phrases uttered constantly by TV talking heads. What’s worse is that these folks flip-flop between “risk on” and “risk off” faster than day becomes night. It’s all about today. It’s all about the last five minutes. It’s all about now. And it flies directly in the face of what it means to be an investor seeking to generate wealth over the long-term. This manic mentality is perpetuated by the media because trading is exciting and exciting makes for better ratings and more mouse clicks. It’s made possible by the massive proliferation of exchange traded funds (ETF’s) over the last decade that allow people to trade just about anything (with leverage) through internet-based investment accounts with cheap commissions. If you so choose, you can now trade every gyration of the Vanguard Mega Cap 300 ETF (MGC), the iShares FTSE NAREIT Mortgage REIT’s ETF (REM), and the iShares MSCI Chile ETF (ECH). Don’t get me wrong, there are those who can and do make big money trading, and that’s been true for decades. But most people can’t, and Wall Street’s myopic focus on being hyper-sensitive to every wiggle and waggle in the market only distracts the average person from the real prize – being a long-term investor. Take last Thursday’s stock market action, which saw large early losses (RISK OFF!) erased in the final 30 minutes on speculation that a cancelled Angela Merkel press conference meant that the Europeans were close to a huge deal. RISK ON! RISK ON! RISK ON! Do you think Warren Buffett was sitting in his office with his eyes glued to a Bloomberg machine, watching every tick? Not a chance. Warren Buffett is an investor. He probably couldn’t even tell you where the S&P 500 closed on Thursday. But he can W Jim Oberweis, CFA Dave Covas, CFA Ken Farsalas, CFA Kevin Cowell, CFA tell you at length about all of his investments and what he believes makes those investments great over the long-term. What does it mean to be an investor? It means buying shares in a company that has a good and sustainable franchise, generates earnings growth, and trades at a reasonable valuation relative to that growth potential. Contrary to what Wall Streeters would lead you to believe, investing is not rocket science. In fact, you can boil it down to this: stock price follows earnings over time, and if you don’t believe me, look at the multi-year price and earnings charts of Coach (COH) and Xerox (XRX), and you’ll catch my drift. Over the last 10 fiscal years ended June 30, 2011, Coach grew its earnings by over 1,300%, and its stock price appreciated by over 1,200%. In contrast, Xerox’s earnings per share fluctuated between $0.65 and $1.21 over most of the last decade, exhibiting no consistent earnings growth. Xerox's stock was actually down over 20% during the 10year period ended December 31, 2011. So as the market goes up and down and all over the place in reaction to every little speculative tidbit and news headline out of Europe, keep your eye on the longterm prize. Focus on companies you know and understand and have products or services that you like. Take advantage of short-term weakness in stock prices to add to the longterm success stories from The Oberweis Report, like Acacia Research Corp. (ACTG), HMS Holdings (HMSY), Imax Corp. (IMAX), and SXC Health Solutions (SXCI). Financial television has become the ultimate in reality TV programming, and unlike the latest episode of Keeping Up With The Kardashians, this mindless drivel can cost you real money. So do yourself a favor and turn off that TV. Block out the short-term craziness and focus on investing in great companies that will allow for long-term wealth creation.

(SSYS-NGS-$49.50) 2011 2012E 2013E Revenue (millions) $155 $1.02 E.P.S. $190 $1.35 $230 $1.75 Stratasys, Inc. is a worldwide leading manufacturer of three-dimensional printers and 3D production systems for the office-based rapid prototyping (RP) and direct digital manufacturing markets. The company’s 3D printers and 3D production systems provide 3D computer-aided design (CAD) users a fast, office-friendly and low-cost alternative for building functional 3D parts. The company manufactures and sells a broad product line of 3D printers and 3D production systems (and related proprietary consumable materials) that create physical parts from CAD designs. The company also offers prototyping and production part manufacturing services through their centers located in North America, Europe and Australia. In many industries, the models and prototypes required for product development are produced by hand-sculpting or machining, a traditional process that can take days or weeks. The company’s computerized modeling systems use their proprietary technology to make models and prototypes as well as enduser parts directly from a designer’s 3D CAD file in hours. This can eliminate machining and tooling costs and allows for inexpensive design changes. On April 16, 2012 Stratasys announced that they entered into a definitive merger agreement with Objet Ltd, a leading manufacturer of 3D printers based in Rehovot, Israel. We believe this pending acquisition, once closed, offers additional upside to earnings in 2013. In the company’s latest reported first quarter, sales increased approximately 30% to $45.0 million from $34.6 million in the first quarter of last year. Stratasys reported earnings per share of $.28 in the latest reported first quarter versus $.21 in the same quarter of last year. Clients of Oberweis Asset Management own approximately 21,300 shares. These shares may be appropriate for risk oriented investors. The company is located at 7665 Commerce Way, Eden Prairie, MN 55344. (952) 937-3000. www.stratasys.com.
