Guys - I think that this is the first time in the history of T2W that we have had a heated discussion on an options subject. Allelulia - This is progress! But can we please keep it civil.
I'm not certain that delta hedging is relevant to a covered call position. Delta hedging is more often used in a situation where there are multiple short positions to keep delta at or close to zero. I am open to persuasion here, but it'll need to be clearly put (pun blatently intended).
I've drawn a pay-off diagram of that compares a covered call and a short put.
Position (A) is a stock at 50 and a call with a strike of 50 sold for 1. If the price stays at 50, then the call expires worthless, the premium taken is retained and there is a profit of 1.
Position (B) is a short put with a strike price of 50, sold for a premium of 1. If the price of the stock at expiry is 50, then the put expires worthless, and the premium of 1 is all profit.
Superimposing (A) onto (B) shows that they are both the same.
With the covered call, if price tanks to 20, then there is a loss of 30 on the shares, but the call option expires worthless so the premium of 1 can be offset against teh loss and the net position is a loss of 29.
With the short put, if price tanks to 20, then the seller of the put will have the shares "put" upon him at 50 and he will only be able to sell them in the market at 20, leading to an immediate loss of 30, although he will still have the premium of 1 to offset against this, leaving a net loss of 29 (as shown in Red - the same as the covered call(Blue).
Now the psychological position between the 2 positions may be different in that the covered call holder doesn't need to take any action other than to cry gently into his beer - he has, after all, already paid 50 for the shares and is nursing his loss. The short put writer, however, will have to stump up the 50 upon expiry in the full knowledge that the shares he is acquiring for 50 are only worth 20 in the market. Of course if he doesn't have 50, then he has more than a psychological problem, and given the temptation to be over-geared, this may have led to regarding naked puts as more risky. But provided that you always have the funds (in this case - 50) set aside to buy the shares if price falls below 50, then the 2 positions are the same.
Has that helped or merely poured petrol on the flames?
BTW - the Charles Cottle free e-book is first class, and I shall add it to the reading list in the Options Trading Guide. Thanks for reminding me of this one Johnk49.
