GPS technology is a sector of tech that's hot right now. Why? Because everyone and everything needs to know where it is, always. Think about it - even when you're dying to get lost from it all, you're really not interested in actually being LOST.
The companies that are really interesting right now are Navteq (NYSE:NVT), Garmin (NASDAQ:GRMN), SiRF (NASDAQ:SIRF), and maybe Magellan (private). I'm personally an investor in Navteq and it has risen by 178% in the last 8 months. The sector is moving in that direction with the ever increasing number of cars that come standard with GPS based navigation, the proliferation of phone based GPS systems like on the Blackberry 8800 (my business phone), and the price decreases seen in consumer devices like the ones from Garmin.
I owned a Garmin eTrex when I was having fun with Geocaching and enjoyed it thoroughly. We'll only see more interest in Navteq data as systems like Google Earth and others become the basis for so many mashups and useful offshoots.
I'm no Jim Cramer, but I firmly believe that GPS tech is a great investment for the next year at least.
