OK, I'll just pick this post to air out some comments here. Let me start off by saying how silly this statement is.
I think picking the right thing to short premium is also pretty important
The reason I am pointing out this statement is because it's not valid on it's own merit. Or at least this statement is not uniquely valid to selling premium. Can't somebody say the same thing on the inverse? That if you are a long premium trader, picking the right stock is very important? Of course they can.
Somebody on another post made the comment that if you pick the right time to sell premium, the odds are in your favor. This of course is completely preposterous. Again, I'm saying this in the context that it is unique to premium selling. Again, can't one say the same thing about buying premium, that one has to pick the right times to do this? I mean, what about the guy that bought calls on GOOG and CME when those stocks broke out to new highs. Certainly they would have been handsomely rewarded for doing so correct?
See, here's the deal. If you make extraneous arguments to your original thesis that selling premium has some edge and you qualify that remark buy saying things like...well you have to do it at the right time, or you have to pick your spots and be disciplined....then how is that different from say a stock index futures trader who says the same thing? I mean one could make trillions of dollars trading NQ futures if they pick their spots well and get in at the right time. Or if they cut their losses and let their winners run. This says nothing about the original post on this thread which was, is there edge in selling options. Once you add qualifiers to that statement, the original statement is no longer valid.
I will say this again, there is no difference between buying a 20 delta option and selling a 20 delta option. Yes, I understand selling the 20 delta options makes you feel safe because it's OTM. But if you run a simple monte carlo simulation on random moves thousands of times over, you will see that your results will be completely identical. You can try this experiment yourself by flipping a coin and running the results on a spreadsheet. Wether you buy heads or sell tails, at the end, the results will be the same over an infinite time period.
Now if someone on here claims they have a great technical system or they have secret indicators that pick tops or bottoms, then fine, that I can live with. But that has nothing to do with options or the probability of an option closing ITM or whether or not it's better to sell premium over buying premium.
Let me repeat, none of my statements are saying one can't sell premium profitably, only that there is no advantage to selling premium over buying it. The odds are exactly the same. There is no way around this. A 20 delta option is a 20 delta option is a 20 delta option. LOL.
