I bought Kontron in the last few days. This has made it one of my top 5 stocks in the portfolio. The timing was lucky.
A new order for EUR 40m leads to a rise in the share price of EUR 3 today. This increases the market capitalization by around EUR 190m in one day.
I think that's exaggerated, but I'm happy about the share price increase. :)
Other European tech stocks in my portfolio and also in my top 5 are:
Init Innovation and Nagarro. All 3 have a P/E ratio of around 20 or less and good growth prospects.
