@frommi: i don t think "nwli" or "hornbach" will double in 2016 :)
I think these are good businesses under conservative family control with an track record (not warren buffett like, but who knows the next berkshire or m&t bank??? ).
But the businesses are trading at a fair price and business models i understand.

Another business that is cheap by assets is Sega Sammy from japan (video games, gambling machines, golf courses, casinos etc.). But i think the business ist much more difficult to value. Of course it could be an big winner. The next sonic game could be a pokemon or Grand Theft Auto blockbuster. But too hard to say for me.
I like understandable businesses (for me, i m not the smartest person around) with good asset base i can buy at an fair price. Over time it worked for me :) I found a few big winners in the past; but these findings are rare today.
