The biotech sector saw a significant run-up last month, but for at least one analyst, questions remain about what the second half holds. Mark Schoenebaum, a biotech analyst with Bear Stearns, cautioned Tuesday that on the basis of his research, he expects the sector's performance to be flat through the end of the year. For the 20 trading days in July, biotech stock indices gained more than 10%. Among individual issues, Amgen ( AMGN) was up 31%, Genentech ( DNA) rose 10% and Genzyme ( GENZ) jumped 25%. According to Schoenebaum, historical trends indicate that "the biotech sector is unlikely to suffer a major correction over the next 3-6 months." But at the same time, the "data also indicate that another significant rally is unlikely this year," Schoenebaum wrote in a research note dated Aug. 1. He believes the sector "could remain range-bound" for the rest of the year. Along with his colleagues, Schoenebaum, whose firm does and seeks to do business with the companies it covers, looked at the seven other instances when the Nasdaq and American Stock Exchange biotech indices were each up 10% or more for a 20-day period. Then they examined the performance of the component companies one month, three months and six months after those rallies. Given his second-half assessment, the analyst recommends that investors dump the "basket approach" to the sector and take a closer look at individual companies' products, pipelines, sales and risks.
reported earnings that were 16 cents ahead of estimates, thanks to strong sales across several drug franchises, including Aranesp, Neulasta, Neupogen and Enbrel. Genentech topped estimates by 4 cents with the help of better-than-expected sales of Avastin and Herceptin. Genzyme also turned in a profit that was 4 cents better than estimates, thanks to gross margin improvements. Schoenebaum views Amgen's ongoing pipeline positively, pointing to the experimental postmenopausal osteoporosis drug AMG-162 as an important drug in development. Additionally, he sees Genentech reporting solid second-half profits, buoyed by Avastin and Herceptin, despite possible manufacturing constraints. Although he admits he doesn't love Genzyme, Schoenebaum sees an upside once 2006 arrives -- that's when the Medicare prescription drug program is expected to cover the kidney disease drug Renagel, and the analyst says the coverage isn't fully considered in to the company's sales projections. Schoenebaum has a peer perform rating on Amgen. Genentech, Genzyme, Idenix ( IDIX) and Nabi ( NABI) are rated outperform. Also, the analyst says that among the stocks with peer perform designations, he and his team "see modest potential upside this year" for MedImmune ( MEDI).
