Very insightfull, thank you. That makes complete sense. So it is better to just do the naked put since it requires less margin. I think I am leaning more towards credit spreads; this way I wont be blown out on a gap or fast moving stock.
Quote from momoneythansens:
Sure, let's assume that synthetic equivalents can be substituted for the real thing at any time. At all points on the risk map they are identical.
Let's say you did your covered write. Now, when you aren't looking, I sneak into your account and switch your covered write position with a naked PUT.
Pretend that you don't look at your existing portfolio to make any trading decisions moving forward. Instead you look at the stock price and options chains to see current values of various options. Hope you're still with me.
Now, looking at your adjustment strategies that you outlined: Say you want buy back the call if the stock drops and sell it again on a bounce. What steps do you take?
1) Buy CALL on dip.
2) Sell CALL on bounce.
There's nothing to stop you performing these two trades regardless of what is in your portfolio. In fact, you don't know that you are simply buying a CALL rather than buying back a short CALL. It's the same trade.
With a covered write, when you buy back the CALL you are left with long stock.
With a naked PUT when you buy the same CALL you are left with synthetic long stock.
i.e. you are left with two synthetically equivalent positions. As we have already established the two positions are interchangeable.
If you perform the same action to both positions, you will be left with two further synthetically equivalent positions and so on...
In short, whatever adjustment strategy you have in mind for the covered write can be applied exactly the same way to the naked PUT.
Why is this helpful? When you view the covered write as a naked PUT it becomes obvious that a drop in the stock actually harms the position. It doesn't help it. Although you are realizing a gain in the short CALL (I presume that is the motivation for buying it back), you are losing much more in the stock. Overall there will be a net loss. Buying the CALL then turns the position very bullish (long stock).
Hope that helps.
