Quote from daddy'sboy:
Your reverse collar - 3 steps (short stock, short put, long call)
Synthetic - 2 steps (long put, short put).
That's all.

Strictly semantics here, but I would argue that the collar/reverse collar are actually the synthetic trades, the bull and bear verticals are the natural trades. It takes more pieces to build the synthetic than the natural.
