Hello,
I am lazy to find a source, but most fo you knows this is not a rumor. Nintendo does what we call "stock buyback".
We can assume, as everybody say, that it is a positive sign. But for me, who became recently a shareholder for Nintendo, it is still hard to concretly see what defines a "share" or "stock". Someone says me :"it is a little piece of the society". Ok but do you mean like this desk ? or this computer screen there ? or the 2 chairs there ? a quarter of the surface of this office ?
Here for this last event where Nintendo buys back its own shares, I can't see well what this concretly means, in a financial and mathetematical point of view. What can/will be their interest by this move. Make more profit ofcourse but how, by which mathematical lever they make money in buying their own property.
