Writing options for a living

Quote from thenewguy:

...

Nokia shares are listed on the Helsinki Exchanges, Stockholm, Frankfurt am Main and New York.

.....

There is no way that those four exchanges, and their underlying currencies trade in perfect, or even near perfect efficiency. There are arb ops like this, even for retail guys.

Currency risk, political risk...? You do get excess reward, in expectation, for holding any risk that others want to unload. MM and retail traders also are rewarded for making the markets efficient, I suppose.
 
Quote from Profitaker:

Don't agree. It's either a good time to be selling options or a good time to be buying - it's never both ! Where long term option trading profitability ultimately depends on IV over HV (sold verses bought that is), in your example above you'd be paying a higher vol than you'd sold - a sure losing receipe. long term

IV/HV has nothing to do with it. it's the same as saying there's a good time to be betting red and a good time to be betting black in roulette. after the spin which color to have played is obvious. it's the same with IV. you can't know future volatility. after the fact you can say actual volatility was higher than where i bought IV so i was right. but you can't know this before hand. that's what efficiency is about. every trade is a push.

and with the example, IV was sold (the short straddle) higher than it was later bought (the long strangle hedge). otherwise there could not be any chance of profit.
 
Quote from Samson77:

Guys

Does anyone take into consideration the UNDERLYING ....... :D

I'm being totally serious here!

This is the problem that I have seen with you options guys over and over again.

Sheesh - You guys spend so much time on the MATH of trading, I mean really what's the friggin point if you can't get the direction right :confused:

I'm not being condescending I'm asking seriously.

If the volatility on a GOOG put is HIGH but the stock has topped what the heck do I care if it moves $10 south the next day anyways, even if I want to be safe and decide to write a Bear Call Spread I still don't see what the math has to do with it when I have the direction and timing correct.

Samson... don't you think that maverick74 has been implying that throughout this entire thread? Many times direction is very important factor in building a position, and adjusting/managing it correctly for greater returns.

IMHO ... your point is exactly correct!

this week is an excellent example... I closed many long calls.. and converted my strategies in tune with my "expectations" on ST direction being somewhat lower. Rolled some of these profits into back months (like December) while holding or adding front month shorts (calls). Of course I might have been wrong (and still may be if we get some st v-bottom and head to new highs) but like maverick74 said on this thread..... in the pursuit of decent profits one must consistenly flirt with risks in (options) trading... the key being to keep them reasonable by (among other things) an excellent understand of (options) fundamentals/theory, and consistent improvement of trading skills.

I'm not talking about long term trades, I'm talking about taking advantage of short term discrepencies in the flow of information. Further, if you hedge the trade properly, you are removing any currency risk/political risk there is. That's what including the underlying currencies does.


EDIT: I should say "mitigating" any currency risk, not eliminating, i suppose.

Quote from riskarb:

Appreciate the ad, but it's not relevant to expectancy. No, I don't think you give a damn what vols you pay. I am glad you trade options.

but riskarb.. not everyone is trading the size you likely trade... (given the onerous retail marginning scam-policies)... and perhaps not the style you adopt... thus their margins are different; make any sense or am I off-base here? Not to mention retail margins

Agreed. Then you are contributing toward making the markets more efficient. Hypothetically, if they already are, the cost of the hedge would cancel your gains on the stock side, assuming all elswe equal.

[edit] OK, but then you're mitigating your profit?
 
Quote from thenewguy:

I've been looking around for an example of trades that show inefficiencies for you guys.


look, i have never denied that inefficiencies occur. they undoubtedly occur and they are also undoubtedly short term phenomena that make devising a system for trading them a ticking time bomb.

if inefficiencies did not exist there'd be no reason for the battalions of highly paid folks on wall street. their job is to make the markets efficient by exploiting any arb situations or inefficiencies that show up on the radar. retail customers can devote their time in pursuit of finding these anomalies as well. my only argument is that from a cost/benefit perspective it's nonsensical. so for a retail guy or gal to win at this game accepting that the house has the edge is the first step in approaching the challenge of making money. believing otherwise is living in a fantasy realm.
 
Quote from inandlong:



Expectancy is about hits and misses and profits and losses as they occur following the application of a finite set of rules. Where there is subjective intervention - as is the case in every options trade I have seen discussed on ET by even our most erudite and seasoned veterans - there is no means to determine the expectancy of a trade; rather, one can only determine the expectancy of the trader.


expectancy is completely quantifiable and empirically validated. every trade has zero expectancy at fair value with no commissions.

where i will agree with you is that the only positive expectancy that i've found is in the individual trader.
 
The problem with this thread is that there's so much going on it's easy to lose the plot :confused:. I'll re-post the original quote...

Quote from dummy-variable:
in my opinion, that is why it is always better to convert a winning trade into another position rather than close it for a profit. example: say riskarb's short straddle could be closed for $2 profit but instead adding the strangle converts into a fly position at a net cost $1 better than the current market. it really doesn't matter if the potential max payoff is better than the current bird in the hand gain. the better-than-market-cost fly position is always better than taking the locked profit.
IV has everything to do with it ! If your short straddle could be closed at 10% vol, do you really think you're adding value / improving the position by going long a strangle at 12% vol ? And unless the vol smile goes inverted that's the deal.:confused:
 
Quote from dummy-variable:

well there's the contradiction of this approach. maybe the only way i can explain or justify what i'm calling "converting negative expectancy into positive expectancy" is really a betting scheme. it may be some version of an anti-martingale which pyramids winning bets. the method then appears as a means of leveraging winners while balancing risk.

You might be right in the comparison there, since I don't believe in those either. Everytime you 'leverage a winner' you have an opinion about what will happen next compared to the situation now. Your previous position has no relevance to that.

Suppose you use two different accounts then, in one account you sold the straddle. After a week you decide to buy a butterfly in the other account, and close the straddle in the first account. It's equivalent of course.
The owners of both accounts should ask at any time why this action was taken, without knowledge of the other account.


the negative expectancy limit is inescapable. to me disputing this is like denying that the house has an edge in a casino.

I agree, I'm not disputing that.


yet in both the markets and in casinos there are indisputably a few long term winners. are they merely on a long term lucky streak (the statistical equivalent of someone who guesses heads 10 times in a row and wins) or are they skilled bettors or is it some other x factor?

This is tricky. I think winners are skilled bettors, adjusting their risk when they know their chances are changing. This cannot be done in roulette but it can be done in finite cardgames, like blackjack. Knowing your odds in the future and adjusting accordingly will give you positive expectancy.
No question about that.

Adjusting your position because you have some indication about the future, approaching the market with tools to determine the odds and preposition yourself to profit from it is maybe possible, maybe not. That's not what I'm questioning.

But your decision to convert to another position should only be based on that, not on what you own already (because of previous assumptions about the future).

I consider that approach about the same as 'averaging down' or 'not taking my losses yet' or, yes, 'leveraging winners', now you mention it.
