I am a Canadian, and I am trying to use an "intrinsic stock value calculator" (found here: http://buffettsbooks.com/howtoinvestinstocks/course2/stocks/intrinsic-value-calculator.html#sthash.YmLme4uz.y9zefXwy.dpbs). And the video I have used to guide me is http://www.youtube.com/watch?v=S1wbCieoHs4. The video directs the user to use the ten year treasury note's discount rate, which, as of March 24, is 1.88%.
My question is why does the calculator need that information to calculate the intrinsic value of a stock. To be honest, I don't even know what a ten year treasury note is. As a Canadian, do you think it is wise for me to use a ten year treasury note to calculate such information?
