For a review of how apply both bisection and Newton—Raphson methods, see Kritzman Resorting There are two important and independent features of the to numerical procedures is not always necessary; for the special Black—Scholes Option Pricing Theory , : the risk-neutral case of ATM options, Brenner and Subrahmanyam showed valuation and the assumption that stock prices evolve lognormally that the Black—Scholes formula can be inverted to derive a simple with a constant volatility at any time and market level.

For instance, Duque and Teixeira Lopes define the ing asset price stock, index, foreign currency, etc. The moneyness degree of ATM options formula to derive option values.

As an alternative, one may observe equals 1, for OTM call options it will be lower than 1 and for ITM the market price of the option then invert the option pricing for- mula to determine the volatility implied by the market price. Consequently, option premiums will rise. Option half to converge on the root. They estimated the implied volatil- 4. Pan also selected a similar Exchange WSE. Constituents of the WIG20 index are 20 com- exercise price interval [0.

The Ranking is based on month turnover values calls and the strike price less the futures price for puts with a and free float market capitalization on the Ranking day. The skewed pattern indicates that OTM options are prices of underlying shares whereas dividend income is excluded. The calls around zero moneyness. In the period under analysis 20 June—16 Septem- ber strike prices were every points of index WIG At the beginning of period mentioned above, there were striking prices from up to and level of where S represents the underlying stock price or index value and index WIG20 was about points see Fig.

Between 1st and X the exercise price. It could also be used different levels of mon- 11th September the index level went down from to The eyness in percentage. It seems to be a little bit too late, but however, they were not gives an interval of [0. These allow estimates implied much traded first days. Because on Warsaw Stock Exchange option volatilities under different groups of moneyness values the nearest market any reasonable liquidity is for option series nearest to the or further from at-the-money level.

In fore, it is impossible to extract daily implied volatilities with those our paper we decided to use weighted average as a way to calculate exact moneyness degrees, directly from the available option pre- values of volatility for chosen levels of moneyness. In this method miums.

In order to overcome this problem, volatility values for only two points — one on the left side and one on the right side of different points of moneyness for every day could be obtained from moneyness value are needed. For example, to calculate ATM index implied volatilities for options with given strikes by interpolation value when actual WIG20 level is points, we take implied in different ways. There are many different interpolation meth- ods such as the simplest Piecewise constant interpolation method The value of index ind for moneyness needed for example 1.

With these data points, the cubic version of B-spline The implied volatility values are taken from the Warsaw Stock enables us to draw a curve for the interval contained between the Exchange official website following its method of achieving values. Empirical results Values of implied volatilities are then at least twice as those of months before.

Besides characteristic growing shape of smiles which can be useful in our analysis. It concerns three points time-dependence of implied volatility, we can observe here the smile, which means that the center point is at-the-money level, jump of volatility between June and September. In this paper we take are presented. The values of implied volatilities for moneyness under investigation three such groups of moneyness values: 0.

These seventeen types which we propose here represent all possible cases of three points three moneynesses graphical Table 1 patterns. Nr Type of Smile Abbr. But in this paper we follow 2 Left Smile LS the precise, strict classification. In Smiles the at- the-money the middle point is always below or above reversed 11 Right smirk RK smiles other two points, while in Smirks, this at-the-money point has volatility between volatilities of two others.

We can note that 12 Reversed Left Smirk RLK smiles, smirks and ups are convex in shape, while reversed ones and downs are concave functions. The daily changes of this index had risen threefold—fourfold during period of drops. Characteristically, at the high-volatility day, the right tail of volatility curves situate higher, than before.

First Table 3 , given period presents implied volatilities curves for the most volatile week for was divided into three as follows: before jump of volatility call and put options with expiring day of Because of different period length the val- The smile type classification analysis is presented in Table 3.

The ues in Table 4 are in percentage. Besides for possible , rather than Reversed Right Smirk 73 , Right Smile Right Smirk for puts, there are no other characteristic types of smile, 60 and Left Smile Never occurred seven theoretical types, it which appears with considerably greater frequency.

Decreasing character of number Right Down and Full Smile. Left and Right Slash, as well as Reversed of Left Smirks for call options from more than two-thirds to 7.

So, in first period, Left Smirk is the Down, Right Down are not presented in the columns because they most popular for calls and Reversed Right Smirk for puts.

In second, did not occur at all. The calls rather than puts. So, we can see here Smile this is more typical for bigger moneyness distance from a changing character of smiles preferred. These are presented below Fig. Typical calls and puts patters. Smirk, Right Smile and Left smile are the most common. For put as well as Reversed Right Smile have occurred only several times options for first two months Right Reversed Smirk has the highest no more than 4.

Reversed Right Smile was never the case for put that decreasing character of number of Left Smirks for call options options, it occurred only for calls.

In second, Left Smirk is still the most of 5. The last period is a domination less Reversed Right Smirks In comparison with previous studies, smile 6. Exchange WSE during the volatile summer of In this period, We believe that our research may modestly contribute to under- the value of main index of Warsaw Stock Exchange market WIG20 stand the volatility smile behavior in the Warsaw Stock Exchange.

Polish option market is not very liq- behave between Polish and Spanish options markets taking into uid, thus we investigate the volatility smile derived from call and consideration calls and puts options on IBEX We have taken into consideration September expiring series. In Bates, D. The crash of Was it expected?

The evidence from options order to estimate the implied volatility by linear interpolation, we markets. Many of the tricks in Warsow originate from the Quake series, including circle-jumping, bunny hopping, strafe-jumping, double jumping, ramp-sliding, and rocket jumping, but Warsow also gives players the ability to dash, dodge or wall jump, tricks that were originally possible in Urban Terror. It uses a separate button for most of the special movements, making it easier to use them while doing other things at the same time.

The various movement tricks combine to add an extra dimension to the gameplay; as the player's proficiency at moving increases, they are able to collect health, armor and weapons more quickly, and to overpower less capable enemies.

The variety and flexibility of the physics has spawned an entire community dedicated to competing on the various Race maps that the game offers.
