The difference between a put and a call is shares.
To convert a put to a call you use spot. Each natural position has a synthetic equivalent. A put is a call when spot is used.
Long call = long spot; long put. The long spot+put is the synthetic long call.
Short put = long spot; short call. The covered call is a synthetic short put.
Long XYZ at 100; short 70C at $30.5. Put is valued at $0.5 (absent rates/divs).
Trading the XYZ CC is equivalent to shorting the put at fifty cents.
They are equivalent in all ways other than the forward while holding the position (rho).
