Test and measurement equipment maker Giga-tronics may be a micro-cap company, but its new radar testing equipment has massive potential, says Jamie Weston, Managing Director at Spring Mountain Capital. Weston says the company is undervalued on a PE basis and will grow substantially should this new technology be adopted by the military. He is also bullish on American Power Group, which is up over 50% year-to-date, due to the money-saving potential for its diesel conversion systems for trucks.
