In the Ãºltimo artÃculo, must learn about " delta". We follow. Gamma: Gamma drift of Delta is the probability of a change in the Delta. TambiÃ©n informs beforehand if the Delta podrÃa to be changing. Gammas is positive as much for the purchase and sale. When the options are lost in the money of deep of the money of the Gammas serÃnear zero as the probability of a change in the Delta is very low. In the same way in the price of exercise it is probable that to mÃs high and Gamma. Theta: Time of decay ³ n in options like Theta is reflected in posiciÃ. Options of purchase are Theta negatives, which means that each dÃa that does not sell that opciÃ ³ n, the value of time estÃdiminishing due to descomposiciÃ ³ n of the time. In this case, time of decay is reason why ³ n is worse for the buyer of opciÃ. When you sell options, Theta is positive, which means that the decay moment is good for the salesman of opciÃ ³ n. Fertile valley: ÂCÃ ³ mo affects to the volatileness of valoraciÃ ³ n of options is reflected in the one of Fertile valley. In other words, its sensitivity to volatileness. Options tend to have increases of prices when the underlying assets of volatileness are increased. In this case, volatileness is good for the bad buyer of one opciÃ ³ n and for the one salesman opciÃ ³ n. Fertile valley is positive for opciÃ ³ n of length and negative for opciÃ short ³ n. Rho: Rho is cÃ ³ mo the rates of interÃ©s affect the price of opciÃ ³ n. When the rates of interÃ©s are high and is good for the position, Rho serÃpositive. If the rates of interÃ©s are high, but bad for posiciÃ ³ n in options, Rho serÃnegative.

The salesman of a time of propagaciÃ ³ n of purchase opciÃ ³ n mÃs near month and sells opciÃ external ³ n months in one proporciÃ ³ n of one by one. In order to benefit from the sale of the time of propagaciÃ ³ n, the two salesman must look for cosas.& #13; First disminuciÃ is one ³ n of implÃcita volatileness. As volatileness falls, opciÃ ³ n of months (that the salesman is short) loses money mÃs rÃI ask that opciÃ ³ n month prÃ ³ ximo (that the salesman is long) due to the greater Fertile valley in opciÃ ³ n of months was. This harÃthat propagaciÃ ³ n of contract or to lose value and serÃprofitable the salesman to stagger in tiempo.& #13; The second thing that a salesman must look for is a movement in acciÃ ³ n. A time of propagaciÃ ³ n is the part mÃwide s, the point mÃexpensive s when one is in-the-money. A movement that moves away of strike in any direcciÃ ³ n diminishes the value of the differential. While poblaciÃ ³ n moves in any direcciÃ ³ n far from strike, posiciÃ ³ n of the salesman can be profitable if the decay time does not surpass to the movements of stocks.& #13; The time, lamentably, never works in favor of the salesman of extended time. Whatever mÃs opciÃ ³ n months (that the salesman is long), naturally decays to a rate mÃs rÃI ask that ³ n does opciÃ of months (that the salesman is short). These rates of atenuaciÃ ³ n different to cause propagaciÃ ³ n to extend and increase of value, that produces pÃ©rdida a salesman to stagger in tiempo.& #13; The increase of implÃcita volatileness is tambiÃ©n detrimental for the potential gains of the salesman of extended time. When it increases volatileness implÃcita, opciÃ ³ n of months was (that the salesman is short) the increases of value mÃs rÃI request that opciÃ ³ n month prÃ ³ ximo (that the salesman is long). This must to the increase of opciÃ ³ n Fertile valley month outside which expansiÃ creates one ³ n in propagaciÃ ³ n and increases to its resulting value in a negative for the salesman propagaciÃ ³ n.& #13; The salesman, in teorÃa, has a pÃ©rdida potential of limitless. The potential of pÃ©rdida mÃxima not estÃdetermined as much by the movement of the prices but by the movement of implÃcita volatileness. Like salesman, you pasarÃlong time the call months in front and cuts to the call to end meses.& #13; The call to end months serÃn mÃs sensible to the movements in implÃcita volatileness due to a greater Fertile valley sensitivity or the component of volatileness. If the increases of implÃcita, then volatileness the salesman opciÃ ³ n to short, month to end aumentarÃmÃs in value that serÃlong of the salesman, opciÃ ³ n months in front. This harÃthat propagaciÃ ³ n to extend or to increase to its value – a refusal for vendedor.& #13; The second risk is that opciÃ ³ n of the salesman is long is going to expire approximately 30 dÃas before elecciÃ ³ n of the salesman is short. If oa does not diminish volatileness poblaciÃ ³ n does not move far from the strike of significant way before opciÃ ³ n of length of the salesman expires, (s) that short to left one opciÃ ³ n of naked or without cover and one pÃ©rdida in posiciÃ ³ n.& #13; If the salesman can hope to that posiciÃ ³ n, pÃ©rdida of value extrÃnseco of opciÃ short ³ n is retainable. This opciÃ ³ n tambiÃ©n has a limited life and must undo of its value extrÃnseco, does not concern cuÃnto, by its lapsing. The problem that faces the salesman is that situaciÃ ³ n no longer estÃplace setting and the salesman faces at risk ilimitado.& now; #13; Once ³ n expires opciÃ long leaving dueÃ±o of a short call undresses now, the movement of prices of action in direcciÃ mistaken ³ n is an important risk and in the described conditions previously, great problema.& #13; Whereas the salesman can hope to that a movement of the implÃcita volatileness that creÃ ³ an increase in the value extrÃnseco, that probably not serÃable to wait for to that a great movement of negative stock creaciÃ ³ n of an increase in the value intrÃnseco. In that case, the salesman must take measures to avoid pÃ©rdidas substantial once a month in front expires. atenciÃ ³ n to implÃcita volatileness in opciÃ ³ n mÃs far when opciÃ ³ n mÃs near month expires can save to the pÃ©rdida salesman of a great one.

In order to be able to calculate the volatileness of propagaciÃ ³ n, we must equal volatilenesses of the options individuales.& #13; First of all, we are going to move of June of calls being moved the implÃcita volatileness of June by 40 to 36, one disminuciÃ ³ n of four garrapatas volatileness. Four volatileness of the garrapatas, multiplied by a fertile valley of. 05 by tick give a value us of $. 20. To continuaciÃ ³ n we reduced $. 20 of June the present value of 70 opciÃ ³ n of $ 2. 00 and obtains a 36 value of $ 1. 80 to volatileness. Now the two options are evaluated in a base volatileness igual.& #13; As far as this first adjustment in which trasladÃ ³ the 70 of June of volatileness up to 36 from 40, we have a value of $ 1. 80 to 36 volatileness. 40 August call volatileness has a value of $ 3. 00 to 36. Therefore propagaciÃ ³ n valdrÃ$ 1. 20 to 36 volatilidad.& #13; If you want to move August 70, solicits that, you tomarÃa the fertile valley August of call of 70. 08 and multiply by four the difference of implÃcita volatileness of garrapatas.& #13; This gives a value him of $. 32 that must be aÃ±adir to the present value of August of 70 calls with the purpose of to take it until an equal volatileness (40) with 70 June of call. To add $. 32 to 70 of August of call give to 3 dÃ ³ him lares. Value of 32 in the level of volatileness of the new ones of 40 that is the same level of volatileness that June 40 llamadas.& #13; Now, ours expansiÃ ³ n is a value of $ 1. 32 to 40 volatileness. August 70 calls of $ 3. 32 except 70 June to two the calls of dÃ ³ lares. 00 to fix the price of propagaciÃ ³ n to 40 volatilidad.& #13; ³ n does not make any difference of opciÃ that to move. The point is to establish the same level of volatileness for both options. Then already estÃready to compare apples with apples and the options to the options for a value of propagaciÃ exact ³ n and level of volatilidad.& #13; Since now we have an equal base of volatileness, we can calculate propagaciÃ ³ n of fertile valley taking the difference between opciÃ ³ n from two fertile valleys individual. In the previous example, propagaciÃ ³ n fertile valley is. 03 (. 08 -. 05). The fertile valley of propagaciÃ ³ n calculates finding the difference between those of the fertile valley of the two individual options, because in the time of propagaciÃ ³ n, that pasarÃlong time one opciÃ ³ n and cuts the other opciÃ ³ n.& #13; As volatileness moves a garrapata, you ganarÃthe value of fertile valley one of the options at the same time of losing the value fertile valley of the other. Therefore propagaciÃ ³ n of fertile valley must be equal to the difference between the fertile valley of two options. Therefore, ours expansiÃ ³ n is a value of $ 1. 20 to 36 with a volatileness. 03 fertile valley or $ 1. 32 to 40 with a volatileness. 03 vega.& #13; Returning to our value difusiÃ original ³ n of $ 1. 00 with a fertile valley from. 03, now we can calculate the volatileness of which propagan.& #13; We know the difference is a value of $ 1. 20 to 36 of volatileness with a fertile valley of. 03. Therefore, we can suppose that the commerce of difusiÃ ³ n from $ 1. 00 deberÃto develop a commercial activity in a volatileness smaller than 36.& #13; In order to know cuÃnto mÃs under is in the first place to take care of the difference both enters values extended and that is of $. 20 ($ 1. 20 to 36 volatileness less $ 1. 00 a? Volatileness). Soon we divided $. 20 by fertile valley propagaciÃ ³ n of. 03 and we obtain 6. 667 garrapatas volatileness. To continuaciÃ ³ n, to reduce 6. 667 garrapatas volatileness of the volatileness of 36 and we have 29. 33 of volatileness for the commerce of difusiÃ ³ n from $ 1. 00.& #13; TambiÃ©n can determine the volatileness of propagaciÃ ³ n like changes of prices of propagaciÃ ³ n. We are going to fix the price of difusiÃ ³ n from $ 1. 30. In order to calculate this, first we must have the value of propagaciÃ ³ n ($ 1. 20 to 36 volatileness) and of finding the difference in dÃ ³ lares between Ã©ste and the new price of propagaciÃ ³ n ($ 1. 30). The difference is of $. 10. This difference in dÃ ³ lares now is divided by the fertile valley of the differential. $. 10 divided by the difference. 03 fertile valley gives to a value of 3. 33 garrapatas volatileness him. Soon one adds the 3. 33 garrapatas to the volatileness of 36 and propagaciÃ is obtained 39. 33 like the volatileness of the interchanges ³ n from $ 1. 30.& #13; Double-Go to verify our work by means of cÃlculo of the volatileness of the other manera.& #13; This time we are going to do cÃlculo moving the August 70 calls to the volatileness of the base of the June equality 70 calls. SegÃºn the calculated thing previously, the August 70 calls tendrÃa value of $ 3. 32 to 40 volatilidad.& #13; The June 70 two calls are worth dÃ ³ lares. 00 to 40 volatileness. AsÃ, the difference is a value of $ 1. 32 to 40 volatilidad.& #13; Now we are going to move the new price extendiÃ ³ to $ 1. 30, $. 02 mÃlow s that the value of propagaciÃ ³ n to 40 volatileness. Like before, we took the difference in the prices from propagaciÃ ³ n. The result is $. 02 ($ 1. 32 – $ 1. 30). Then, it divides $. 02 by fertile valley ours expansiÃ ³ n of. 03 (it remembers that the fertile valley of propagaciÃ ³ n is equal to the difference between the fertile valley of the two individual options). $. 02 divided by. 03 give a value us of. 67. That. 67 the volatileness of our base of 40 is due to remain. That gives 39 us. 33 (40 -. 67) the volatileness of the interchanges propagaciÃ ³ n from $ 1. 30. This volatileness responds ours cÃlculo previous to perfecciÃ ³ n.& #13; Perhaps at first sight, it is asked for quÃ© we went to travÃ©s of all these cÃlculos. With the June 70 calls to 40 volatileness, the two price of dÃ ³ lares. 00, fertile valley. 05 and 70 of August to the 36 calls of volatileness, the three price of dÃ ³ lares. 00, fertile valley. 08 Âby quÃ© not to have an average of volatileness? This us darÃa a volatileness 38 for difusiÃ ³ n with a price of $ 1. 00 when in fact $ 1. 00 in extensiÃ ³ n represent 29. 33 volatilidad.& #13; This serÃa almost nine by garrapatas ones difference that represents a friolera error of 30%! Because, as it were said previously, Fertile valley is not linear, every month of way cannot be weighed uniforms and finishes both taking an average from months. By the love of argument to suppose it did that it. We say that you find the difference of fertile valleys of the options and came above for with one propagaciÃ ³ n of the fertile valley. 03 that is the correct one. Nevertheless, when ³ n tries to calculate the volatileness of propagaciÃ and the price that tendrÃan dificultades.& #13; Now, ³ n with the price of cotizaciÃ returns to calculate propagaciÃ ³ n of $ 1. 30, or $. 30 mÃhigh s that its value in 38 volatileness. It divides that $. 30 fertile valley differentiates superior in difusiÃ ³ n from. 03. You obtain an increase of 10 by garrapatas volatileness. AÃ±ade that increases to base 38 volatileness. That means that you feel propagaciÃ ³ n negotiates to 48 volatileness instead of 39. 33 volatileness! This type of error podrÃa to be very, very expensive. It remembers, apples with apples, oranges with oranges. It does not matter that volatileness opciÃ ³ n of propagaciÃ ³ n to move the time as both options for a volatileness of the equality base.
