Two tech firms recently added to his portfolio are: ATMI (ATMI), a supplier of specialty chemicals and copper items used by semiconductor makers; and Keithley Instruments (KEI), which manufactures test and measurement equipment such as spectrum analyzers for laboratories, telecom-service providers and semiconductor producers. Keithley is starting to make radio frequency analyzers, which should become more popular since new communications standards are about to go into effect. At a recent price of $2.07 (down from a 52-week high of $12), a market cap of $33 million and $27 million in net cash, Keithley shares are a bargain, he says. The company, which lost 16 cents a share in 2008, has the potential to earn 60 cents within two years, Galluccio says. At a price-to-earnings multiple of 12, the stock should fetch $7, he adds.
