I think we can make a comparison with the stock market.
When stocks are cheap ( beginning of 2009 ) nobody wants them.
Then they start rising, very slowly at first, you get some corrections but stocks keep going higher.
Then you get a moment when prices are really getting crazy, price-earning ratio's sky high.
New money ( that was kept on the sideline ) and new guys ( the ones that will burn their fingers ) are coming in.
Buying is no longer based on fundamentals but on greed and on the wrong assumption that since prices are going up so fast it must mean there is some good news.
The real experts stop buying, they know what is coming and they already bought when there was blood in the streets and nobody was interested.
Interesting thing to know is that in the last fase prices can get much higher very fast.
Getting out too fast can cost you a lot, staying in too long even more.
Is this happening with Heuer right now?
I am not an expert. :-)
