The authors approximate the basket by using the shifted log-normal distribution with the polynomial expansion, which can match exactly any required m moments of the basket, to give quasi-analytical formulas for the prices and hedging parameters of basket options. Numerical simulations show that the methodology provides superior results for basket option prices and hedging parameters.

The strategies benefit from the fact that the implied volatility of options is generally higher than actual realized volatility. In this article, we show that this premium is higher at elevated levels of implied volatility (as represented by the VIX index level). Based on this finding, we propose a simple conditional strategy in which one sells options at elevated levels of the VIX. Using data from 1990 through 2018, we find that this conditional strategy outperforms both the market and continuous option-selling strategies on an absolute and risk-adjusted basis.","PeriodicalId":34223,"journal":{"name":"Jurnal Derivat","volume":"26 1","pages":"38 - 49"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3905/jod.2018.26.2.038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46366624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implies that a straightforward application of the Monte Carlo method is not available and the need arises to resort to time consuming nested simulations or to the least squares Monte Carlo approach. We propose to compute common risk measures by using the celebrated binomial model of Cox, Ross, and Rubinstein (1979) (CRR). The main advantage of this approach is that the usual construction of the CRR model is not influenced by the change of measure and a unique lattice can be used along the whole policy duration. Numerical results highlight that the proposed algorithm computes highly accurate values.","PeriodicalId":34223,"journal":{"name":"Jurnal Derivat","volume":"26 1","pages":"86 - 94"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3905/jod.2018.26.2.086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43298500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we discuss the goodness of fit, smoothness, and economic implications of 12 distinctive curve-fitting methods. The choice of method relies on specific requirements. When fitting the Chicago Board Options Exchange data, three interpolation methods were found to provide the best goodness, whereas quadratic regression, the Nadaraya–Watson kernel regression, and the theoretical Carr–Wu model generate the smoothest surfaces. Because of the irregular nature of the emerging options market data, we propose a transformation method to improve three statistical methods to satisfy the Lee’s condition. Empirically, quadratic regression provides the best goodness when fitting the China 50ETF options data. In addition, the Carr–Wu model is a very good alternative because it natively satisfies the Lee’s condition and has economic implications.","PeriodicalId":34223,"journal":{"name":"Jurnal Derivat","volume":"26 1","pages":"19 - 37"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3905/jod.2018.26.2.019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41633308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because convertible bond pricing requires time-consuming finite difference or tree pricing methods in general, such proxy formulas can help to calibrate model parameters more efficiently.

Hence, the quality of the approximations stands and falls with the value of the early conversion premium.

The model prices for TIPS resulting from this pricing framework are found to most closely fit the 10-year notes issued following the 2008 crisis. Considering these notes accounted for over 70% of the total TIPS-market trading activity, this result underscores the importance of properly assessing DPO value in times of deflationary fears compounded by rising real yields, negligence of which may well be liable for the post-crisis mispricing in TIPS.","PeriodicalId":34223,"journal":{"name":"Jurnal Derivat","volume":"26 1","pages":"50 - 69"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3905/jod.2018.1.069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47823072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the panel quantile regression model, this article finds that the effects of informed trading activity on CDS spreads are asymmetrical across firms with different levels of credit conditions. Further, these asymmetric dynamics behave in opposite directions across different economic conditions. In particular, when economic conditions are good, a negative (positive) relation between informed trading activity and CDS spreads is documented for firms with bad (good) credit conditions. When economic conditions are unfavorable, catastrophic news dominates investment decisions, and a reverse asymmetrical dynamic between the two variables is then observed.","PeriodicalId":34223,"journal":{"name":"Jurnal Derivat","volume":"26 1","pages":"70 - 85"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3905/jod.2018.1.070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42380442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the single-stock Black–Scholes market, Ordentlich and Cover (1998) only priced this derivative at time-0, giving . Of course, the general time-t price is not equal to . The author completes the Ordentlich–Cover (1998) analysis by deriving the price at any time t. By contrast, the author also studies the more natural case of the best-levered rebalancing rule in hindsight. This yields , where b(S, t) is the best rebalancing rule in hindsight over the observed history [0, t]. The author shows that the replicating strategy amounts to betting the fraction b(S, t) of wealth on the stock over the interval [t, t + dt]. This fact holds for the general market with n correlated stocks in geometric Brownian motion: C(S, t) = (T/t)n/2 exp(rt + b′Σb·t/2), where Σ is the covariance of instantaneous returns per unit time. This result matches the O(Tn/2) “cost of universality” derived by Cover in his “universal portfolio theory” (1986, 1991, 1996, 1998), which super-replicates the same derivative in discrete-time. The replicating strategy compounds its money at the same asymptotic rate as the best-levered rebalancing rule in hindsight, thereby beating the market asymptotically. Naturally enough, the American-style version of Cover’s Derivative is never exercised early in equilibrium.
