I don't thinkn HIMX 'tips their hat' on earnings or news. Just look at how the Google pruchase of an equity stake in Himax displays came out of the blue..............there was no leaking there and I think management is very ethical.
There had to be various people involved in the Google purchase and yet the stock did not run up in anticipation of news.
Even the quarterly action seems pretty subdued...............although it generally takes off after a few days of selling. Look at the past earnings............it usually sells off slightly for a few days and then recovers and heads upwards.
But, i see HIMX as very ethical and they do not tip anyone off on news or earnings that I can tell by watching for a year now.
