Economic turmoil and geo-political turmoil go hand in hand, says Justice Litle. That’s why the threat of war is rising in many parts of the world. And that’s why defense stocks could be in for a good year. Justice says AeroVironment (NASDAQ:AVAV) – which develops hi-tech military equipment – should be on investor’s radar screen right now.

Martin Denholm says wind power is taking off in the US. And big players such as T. Boone Pickens and Michael Blooomberg are throwing their weight behind the industry.

For investors who want to minimize risk in a relatively new industry, Martin recommends General Electric (NYSE:GE) and Siemens AG (NYSE:SI). These blue chips are making significant investments in wind energy projects.

Meanwhile, small-cap AeroVironment (NASDAQ:AVAV) is well placed in the emerging market of home and office-based wind power generation.

Unmanned aircraft producer AeroVironment (AVAV:NASDAQ) is now the only company with a nano-sized plane in development, at least as far as DARPA is concerned.
