Think about it, ASML produces as much as possible in the last years, but since semiconductor market raise demands, who should you select, when ASML can not deliver in time or is to expensive?
In the end, they need this machines now (before!!!) they can sell their product. For sure, they buy from TSMC most of the time, but how should TSMC expand? (or Samsung, INTEL)
So I think it is a good general investment in Semiconductors right now to go Nikon & Canon.
Actually they are not hyped or in focus, but maybe will in the next year or even this year? A good long term invest is possible in both stocks! Most people only think digital cameras are outdated (and they are right), but this is not the only product this companies have to offer!
