Pablo,
Thank you for your clarifications. To my shame I never had a real experience with options, just wikpedia's and investopedia's related articles, so european rules have nothing to do with my ignorance and confusion. Apparently I derouted you by saying "current prices are in most cases still considerably below strike prices". Instead of the word current I had to say bid/ask. Sorry. If everything goes at this pace, the bid/ask prices will not only surpass strike prices, but will remain far below them. And, therefore, those who sells, will lose. Is it correct ?
Another point is why so huge difference in value between current price ($149) and strike prices of the first 90th receipts ?
