I think it should

p = X exp (-r T) N(-d2) - S0 N(-d1)

(p - European put value)

d1 = [ln[S0/X] + (r + sigma^2/2)T]/[sigma sqrt(T)]

d2 = d1 - sigma sqrt[T]

S0 - stock price, X - strike

r = 1% - risk-free rate

sigma - volativity

T - time to expiration

N(x) - normal distribution.

What enters the normal distribution is sigma sqrt(T).

Which means, you gain a lot more on the volativity
rise than you lose in time premium, with long-term options.

If you use this formula to sell options and delta-hedge
options sold, you will make billions with them. Unless,
of course, this house of cards collapses, because N(x) is
the wrong distribution in reality. But Mythman
says it's a myth. So, if Mythman is right, you can have
Fed's printing press at home. All banks do. -g-
