I sold a small remaining batch of Qt at a 10% loss.
I lightened my Fortum position by about half, using all accumulated capital losses that I had cherished long and hard 
I’ll leave the rest in my portfolio, because I’d rather take a write-down than pay taxes. Anders Oldenburg estimated the company’s value at 20e/share, so I don’t think I’m selling at a terrible discount. The company would indeed be good, but I don’t trust the management or the main owner. I’ll return if the price drops to the 15e level or if, for example, a ham sandwich becomes the CEO.
I’m still thinking about what to buy instead. I already bought a little of the OP Nordic index.
