Spreads vs naked

  1. Yes, you made an innocent observation and it took on a life of its own.

  2. Stops with options are much more complicated.

    Would you want to be stopped out of a position because IV changed and that resulted in a loss? I would hope not.

    And getting out of option positions 'at the market' is absolutely a money-losing proposition.

    I was trying to address this in my post at the top of page 6 in this thread. For this discussion I would like to focus on just the option and forget about adding hedging techniques at this time. For the option, the seller will "win" more times but at a fixed or lower rate. The buyer will "win" less times but at a higher average rate. The end result is that there is no inherit advantage to being a seller or buyer. The expected return will be about the same for both.

    The key to solving this for me is to find set-ups and or situations that will give you a statistical expected return that will cover spread, commissions and desired return (edge). I want to clarify what I mean by this last sentence but I will use wagering on horses to convey my meaning as this is how I see it.

    I'm going to backtrack for a moment to address the more wins concept discussed earlier. If I told you I have two systems of wagering on the horses, one that has a winning wager 1 out of 2 wagers and one that has a winning wager 1 out of 3 races, which would you say is better? Depends on what your criteria is. If your criteria is to cash as many tickets as you can, then the first system is better. However, if your criteria is the one that has the greatest expected return, then you need to know what is the average return for each system. If system 1 returns on average $3.60 for every $2 wagered, you would make two wagers, $4, to collect $3.60 for a loss on 10% for every dollar wagered. If system two returns on average $6.60 for every $2 wagered, you would make three wagers, $6, to collect $6.60 for a gain of 10% for every dollar wagered.

    Now the application of the above to my point. If using system 2 I collected the win on the first wager, it does not mean that my expected return is 230%, I know somewhere along the way I will lose two other wagers to bring my expected return back in line with the true expectation of 10%. IMO this is the mistake that I see when FOTM options are touted as a "conservative" strategy. They don't allow or plan for the returning to the real expected return because the strategy gives them many more wins. The problem is of course that those many small wins can be totally wiped out and then some by the very few large losses.

    I hope that is clear. Please note that this is how I approach and view things. This is not to say that there are not any other successful approaches that are different. I know that there are many other successful approaches. This is just the approach that I use. I analyze a problem this way (whether it be stock market, options, horse-racing, sports betting, jai alai, casino etc):

    1. If I make totally random "wagers", what is the expected return?
    2. If a negative expected return, what factors make up the negative return?
    3. Once the factors are determined, analyze each factor to determine if the negative effect can be minimized or eliminated.
    4. Test to ensure that that the expected return is positive before use.

    There is still plenty to cover but I'll stop here for now.

    There really isnt a difference in a "continuously" traded framework.Most traders by and large do not apply position sizing algos and MM to option trading.They are under a false pretense that the leverage factor/limited risk should dictate a different approach to trading...i.e SHOOTING...Hence,they choose not to make a business out of it..

    If one decides that the proper posion size is 1000 shares of XYZ stock,why in the world would you select a different delta for LONG option position??

    Its irrelavant that an option is a leveraged instrument.I could leverage a stock position with margin,I could do swaps.Does that mean I should position size differently a long swap position vs cash?Should I now risk more than 2% of equity on any given position??

    You ae wrong about spreads vs naked option positions

    If you were deltal long 50,000 shares of AAPL by being naked Long options,what amount ov verticals would you sell to hedge yourself???

    Thats right,the delta amount.....Anything else is a punt,and hopefully you are a good kicker

  5. Well stated.

    That is the point.
    The main point.
    The only point.

    If you take those occasional large losses, your chance of doing well over the longer term is dismal.

    My initial method of choice for preventing devastating losses is sell spreads, rather than naked options.

    Regardless of how you choose your positions, it is essential to manage risk. That means taking some losses that would have turned into winners, but it also means there will be NO large, portfolio-killing losses.

    Mark,if the purpose of buying options is not to own a position,or should we say REPLICATE a position that is equivalant to owning the stock,then what exactly are you suggesting???

    Are ytou saying since an option has a reduced risk,you should load up???Or are you saying due to the fact that it is a leveraged position you should have a much smaller delta.You need to pick one....

    As for debating when to sell the residual deltas,thats kind of "odd" coming from your point of view.You need to tell us what delta amount of options one should purchase,as you have clearly indicated that its not the equivalant share amount.

    I will add that the residual amount of delta should be adjusted relative to gamma,and I trade with vol adj pos size ,MM with hard stops as well as a time stop.

    Options should not be traded differently than stocks unless one is a 100% discretionary trader who is fully willing to take calculated bets and risk X% of capital....Dont get me wrong,there is absolutely nothing wrong with that approach,but IMHO it still comes down to Deltas or risking x percent of capital.How else can one decide to buy stock vs # of spreads vs # of naked options??

    FYI,buying soon to expire options with large gamm is a different topic

    Mark,much of our differences stem from your view on point #5..I dont agree with your view

    You do not seem to look at option delta's when comapring spreads vs naked options.I think that is a mistake as your P&L will make a very large distinction on a daly accounting basis.

    You simply should not equate a naked option with a .5 delta with an option spread of .25 delta...It really has nothing to do with "reduced risk",gambling and higher profits.

    It seems to me that you look at everything on a terminal expiration diagram....

    Mark,the real problem is,and I do not mean any disrespectbut it certainly appears you are not a directional trader,nor do you think like one.You have a floor traders mentality,and that is why we are speaking different languages

    As an "iron condor" trader,I now understand where you are coming from.Its a much different world.

    How do I know this??

    I too was a market maker on an options exchange,but for 15 years I was the head trader of equity derivatives and emerging market derivatives at a major investment bank.I later ran a fund and cashed my chips in 2006.

    With that said,I have had the good fortune of meeting, and working(trading against as well as covering) with some of the largest "directional traders" at various hedge funds,and I promise you they do not look at things the way you do..Not even close......
