※ 引述《whabcdefg (wh)》之铭言：
: it is about option pricing,
: how to interpret the following statement intuitively not quantitatively:
: the higher the call price the higher interest rate
: while the lower the put price the higher the interest rate
: 3x all
K is excercise price at maturity time
K*e^(-r*t) use interest rate to discount K to now
when r is higher then K is lower
and call = max(s-k,0) more valuable , put=max(k-s,0) less valuable.
