I believe last year <| sep |> Not a problem . Again , that is one part of a much larger company in terms of Thermo Fisher , but I do like tmo quite a bit as it is the largest company serving science . Ecolab , Thermo Fisher , danaher and to a lesser degree Valeo are all longterm holding them for years ahead holdings . I don ' t own 3 m but certainly a great company , as well . NEARLY TWOTHIRDS of Thermo Fisher ' s revenue comes from consumable products , giving investors good visibility . Growth opportunities abound . With some $ 700 million in yearly spending on research and development , Thermo Fisher is focused on making new equipment for gene analysis , portable machines that take the place of bulky ones , new ways to test for allergies and drug abuse , and more . The top three players in the industry control only about a third of yearly revenue estimated at $ 100 billion . The rest goes to hundreds of smaller players . fisherhas 30 upsidetelIf article is blocked , search Google news for Barron ' s thermo Fisher . Research budgets have also increased in China in recent years , and Thermo Fisher has benefited . About 23 % of the company ' s revenue comes from Asia , with 8 % from China , Knight says . And China ' s research outlays are growing . The country ' s leaders are expected to continue to boost the budget , in part because they need to diversify their economy , Knight adds . In addition , China has increased spending on environmental science as it addresses complaints about dirty air , contaminated food , and polluted water . Even if the industrial economy there weakens , research spending is likely to stay strong . They have exposure to areas where China continues to spend money , says Margaret Vitrano , comanager of the ClearBridge Large Cap Growth fund SBLGX . Concerns about air quality and food safety are front and center for them . f ishersalluretelDefinitely research the companies mentioned first to see if they are right for you not only in terms of theme , but otherwise .
