Stratagene Shares Drop 23.3 Percent in One Week

Shares in Stratagene have fallen 23.3 percent over the past week, though the reason for the decline is unclear. The company's shares dropped 15.3 percent last Thursday alone — two days after it announced a settlement with Takara Bio related to PCR enzyme blends, and a day before molecular diagnostics partner Focus Diagnostics announced that it was being acquired by Quest Diagnostics (see Briefs).

Thirteen of the 16 companies in the BCW Index lost value during the tracking period. Thermo Electron led gainers for the week with a 1.2-percent rise in its shares. Overall, the Index declined 2.3 percent for the week ended Tuesday. In comparison, the Dow Jones fell 2.8 percent, the Nasdaq dropped 3.2 percent, and the Nasdaq Biotech Index fell 4.5 percent.
