Vaisala, in my opinion, is a high-quality company that manufactures high-quality products. It seems to be superior in its field, at least in terms of technology, from what I have understood, even though I don’t have a very strong understanding of the technical aspect myself.
As far as I know, it has some growth opportunities and a good profitability, which it can improve to some extent.
In short, one could say it is a really good company, but the stock is always or at least often a bit too expensive in my opinion, or not particularly attractively priced. Currently, it’s not particularly expensive, and there might be some room for growth, but there are also risks such as increasing competition and slow growth.
