Big plans by tiny NeoStem (NBS), which collects and stores adult stem cells for future medical use, have helped catapult its stock to 2.27 a share from 50 cents on Mar. 9. NeoStem applied for patent protection in May for a technology that allows use of an adult's stem cells in cosmetic surgery. And it took a 51% stake in a profitable Chinese drug company with $60 million in sales to distribute stem cell therapies in China.

Rachel Kirsch of Pro-Active Research Group (it did business with NeoStem) rates the stock a speculative buy, seeing it at 5 in a year. Gary Goldstein, president of Mithra Research, says China operations should yield revenues of $50 million a year. His 12-month target: 7.
