And are there ways to improve its return?
Take Goog for example:
Buy X 440 Calls Sell Y 470 Calls Buy Z 430 Puts
Buy X 530 Puts Sell Y 500 Puts Buy Z 520 Calls
Put this position on just as Theta starts to pick up.
The return seems decent with X=Y=Z=1 and as the underlying moves $10 in either direction just repeat and put on another one of these and hold all until expiration.

Yes you are right about that.
