So i've got a start with the trailing months earnings here, which you just google and it'll come up. Im going to say just ten % for a long term growth rate for apple. Is may be sustainable. I'm pretending i don't know the company. And now i can figure out a rough value of the business. So i come up right away. And tells me hundred and six dollars a share is roughly what it's worth. It certain is currently selling for 19 dollars, so the market appears to be pricing this about right. That's how i do it. Boom. Right there.
