Quote from magicz:
Just from personal experience, I think if you concentrate on a smaller number of the underlying and get to know them like the back of you hand. Then it would be better to risk more on a more concentrated porfolio with a higher reward.
Especially, if you are short term option trader then you should get to know your underlying even more because your profit is dependent on short term movement of the underlying.
I hope that didn't confuse you...
Quote from esmjb:
for one, selling spreads means twice the commish. secondly, if one spread goes against you to the max it will take the profit away from 3 of your winners (assuming you collect all of what you sold it for and not less).
this strategy just seems weak to me. you might not lose a lot of money but i really dont think you will make a lot either, even if you size up down the road.

Thanks!
I agree that selling spreads involves two commish. It also means twice negative expectancy. One from commish + b/a spread of buying and one from commish + b/a spread of selling. If I am not too chicken, I'll probably go with naked call/put to minimize the that effect.
My goal is not to loose money first or not loose too much. I realize that my position sizing is not that great.
From my current captial, I'll probably earn more from T-bill than doing this.
Quote from flyers&divers:
I disagree with people who think you are diversified too much and there are some comments from people who do not understand the essence of credit spread trading.
They are legions of people who believe that trading is a zero expectancy game and in this case the $1.50 reward for $5 risk is not high enough.
First, in a credit spread trade you are dealing with out of the money options and time decay is also in your favor. In addition
even the use of the simplest TA such as volatility bands and MA's increases positive expectancy of the trade and you can use all kinds of other info as well like ZAKS and S&P ratings, seasonals, sentiment, special events etc. and you are no longer shooting fish in a barrel like it is assumed in these conversations.
People don't realize or I have not seen it mentioned that there is a different relationship to expectancy here: unlike outright positions credit spreads work most of the time and one's focus is not on cutting one's losses and letting one's profits run but minimizing the effect of the occasional large loss.

The truth is, and most people are not willing to face this (even people in the business), that you should not trade at all until you figured out a method or technique that gives you and edge and beyond that you need to manage yourself and trades well to be successful. Still, the possibility of surviving trading spreads is enhanced by the the benefit of time decay.
