why falling

Here is a company that has some great products, great customers and in the age of Terrorism and Security has a great market.

Yet they have lost 60% of their value since december last year! Sure they first expected a profit but now are going to make a small-med loss - but why such a drop. They are putting money into R&D, they have a P/E ration of 6!

Not many shares on issue.

Yet nobody talks about them - please help me analyze this stock.

Cheers
