Download or read book Does Adverse Selection Affect Bid Ask Spreads for Options written by Söhnke M. Bartram and published by . This book was released on 2019 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines two different option markets to test whether differences in the level of adverse selection faced by market makers affects the size of bid-ask spreads. The data are from bank-issued options that trade on EuWax, where market makers face little adverse selection and traditional options that trade on EuRex. The results support the hypothesis that the adverse selection component of the bid-ask spread is important as options on EuWax have lower bid-ask spreads than comparable options on EuRex. The results show that the adverse selection component represents at least half of the overall bid-ask spread on the traditional EuRex.

Book excerpt: An important feature of financial markets is that securities are traded repeatedly by asymmetrically informed investors. We study how current and future adverse selection affect the required return. We find that the bid-ask spread generated by adverse selection is not a cost, on average, for agents who trade, and hence the bid-ask spread does not directly in uence the required return. Adverse selection contributes to trading-decision distortions, however, implying allocation costs, which affect the required return. We explicitly derive the effect of adverse selection on required returns, and show how our result differs from models that consider the bid-ask spread to be an exogenous cost.

Download or read book The Effect of Decimalization on the Components of the Bid Ask Spread written by Scott Gibson and published by . This book was released on 2002 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous empirical studies that decompose the bid-ask spread were done when securities traded in discrete price points equal to one-sixteenth or one-eighth of a dollar. These studies concluded that inventory and adverse-selection costs were economically insignificant compared to order-processing costs. Natural questions arise as to: (i) whether price discreteness allowed market makers to enjoy excess rents, thus reducing the significance of the inventory and adverse selection costs; (ii) whether discreteness decreased the traders' incentives to gather information; or (iii) whether methodologies previously employed mis-estimated the inventory and the adverse-selection costs. We show that the recent conversion to decimal pricing results in significantly tighter spreads. However, the dollar value of spreads attributed to adverse selection and inventory costs do not change significantly. Almost all of the reduction occurs in the order-processing component. As a result, inventory and adverse-selection costs now account for a significantly larger proportion of the traded spreads. A plausible explanation is that the minimum tick size constraint previously in place under fractional pricing allowed market makers to enjoy spreads that were larger than their actual costs.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we show that George, Kaul and Nimalendran's (GKN) estimators of the adverse selection and order processing cost components of the bid-ask spread are biased due to intertemporal variations in the bid-ask spread. We provide new estimators that correct this bias and that are applicable to individual securities, and estimate these cost components empirically using data on NYSE/AMEX stocks. As expected, our results indicate that on average adverse selection costs account for approximately 50 percent of the bid-ask spread, sharply higher than the estimates of 8-10 percent obtained by GKN for NASDAQ stocks and 21 percent that we obtain for NYSE/AMEX stocks using GKN's estimators. We then conduct cross-sectional regressions designed primarily to determine whether adverse selection costs vary across specialists after controlling for firm size and other factors. Consistent with previously-established hypotheses, we find that adverse-selection costs vary across specialists, and that this variation is related to the number of securities that the specialist handles.
Download or read book Modeling the Bid Ask Spread written by Nicolas P. B. Bollen and published by . This book was released on 2012 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to understand and measure the determinants of market maker bid/ask spreads is crucial in evaluating the merits of competing market structures and the fairness of market maker rents. After providing a brief review of past work, this study develops a simple, parsimonious model for the market maker's spread that accounts for the effects of price discreteness induced by minimum tick size, order-processing costs, inventory-holding costs, adverse selection, and competition. The inventory-holding and adverse selection cost components of spread are modeled as an option with a stochastic time to expiration. This inventory-holding premium embedded in the spread represents compensation for the price risk borne by the market maker while the security is held in inventory. The premium is partitioned in such a way that the inventory holding and adverse selection cost components and the probability of an informed trade are identified. The model is tested empirically on a sample of NASDAQ stocks over three distinct tick size regimes and is shown to perform well.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last 20 years hedge funds and derivatives have fluctuated in reputational terms; they have been blamed for the global financial crisis and been praised for the provision of liquidity in troubled times. Both topics are rather under-researched due to a combination of data and secrecy issues. This book is a collection of papers celebrating 20 years of the Journal of Derivatives and Hedge Funds (JDHF). The 18 papers included in this volume represent a small sample of influential papers included during the life of the Journal, representing industry-orientated research in these areas. With a Preface from co-editor of the journal Stephen Satchell, the first part of the collection focuses on hedge funds and the second on markets, prices and products.
Download or read book The bid ask spread of bank issued options written by Giovanni Petrella and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we apply a structural model to investigate the main determinants of the bid-ask spread for Australian covered warrants. These instruments are also referred to as bank-issued options. They have been mainly promoted to retail investors, and have attracted the interest of market practitioners and academics, based upon their tremendous growth in trading volume across several stock exchanges. Three main determinants are found that significantly contribute to the size of the warrant bid-ask spread. The first two determinants relate to the inventory risk management practices of market makers and include the initial cost of setting up a delta neutral portfolio, as well as rebalancing costs to keep the portfolio delta neutral. This particular result validates that the spread of warrants are positively related to the spread of the underlying asset. The last determinant relates to adverse selection costs, where market makers incorporate a reservation bid-ask spread to protect themselves from scalpers. No evidence is found to show that a higher level of market competition among warrant issuers leads to a narrower warrant spread.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a cross-market model to extend Huang and Stoll (1997) by utilizing information from trade flows in the options market. Empirical tests reveal a significant increase in the estimated adverse information component. This increase is observed irrespective of the degree of option leverage. Further, intraday variation in stock bid-ask spread components are affected by the stock trade size and the extent of imbalance in information-based option trades. Including information from the options market enhances the estimation of the stock bid-ask spread decomposition.
Download or read book Options Illiquidity written by Ruslan Goyenko and published by . This book was released on 2015 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the determinants of options illiquidity measured with relative bid-ask spreads of intraday transactions for S&P 500 firms over an extended time period. We find that market makers' hedging costs significantly impact options illiquidity with the future rebalancing cost dominating the initial delta-hedging cost. Inventory demand pressure and adverse selection also contribute to variations in options illiquidity, with the latter effect intensifying around information events. We find option-induced order flows predict their underlying returns only when options illiquidity simultaneously increases. This suggests that shocks to options illiquidity help distinguish abnormal order flows that contain private information from those induced by liquidity trading. We show a simple strategy that uses high-option-illiquidity stocks and yields 16.5% in risk-adjusted returns per year.

This book was released on 2009-05-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foreign exchange market is the largest, fastest-growing financial market in the world. Yet conventional macroeconomic approaches do not explain why people trade foreign exchange. At the same time, they fail to explain the short-run determinants of the exchange rate. These nine innovative essays use a microstructure approach to analyze the workings of the foreign exchange market, with special emphasis on institutional aspects and the actual behavior of market participants. They examine the volume of transactions, heterogeneity of traders, the time of day and location of trading, the bid-ask spread, and the high level of exchange rate volatility that has puzzled many observers. They also consider the structure of the market, including such issues as nontransparency, asymmetric information, liquidity trading, the use of automated brokers, the relationship between spot and derivative markets, and the importance of systemic risk in the market. This timely volume will be essential reading for anyone interested in the economics of international finance.
Download or read book Modeling the Impacts of Market Activity on Bid Ask Spreads in the Option Market written by Young-Hye Cho and published by . This book was released on 2010 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we examine the impact of market activity on the percentage bid-ask spreads of Samp;P 100 index options using transactions data. We propose a new market microstructure theory which we call derivative hedge theory, in which option market percentage spreads will be inversely related to the option market maker's ability to hedge his positions in the underlying market, as measured by the liquidity of the latter market. In a perfect hedge world, spreads arise from the illiquidity of the underlying market, rather than from inventory risk or informed trading in the option market itself. We find option market volume is not a significant determinant of option market spreads. This finding leads us to question the use of volume as a measure of liquidity and supports the derivative hedge theory. Option market spreads are positively related to spreads in the underlying market, again supporting our theory. However, option market duration does affect option market spreads, with very slow and very fast option markets both leading to bigger spreads. The fast market result would be predicted by the asymmetric information theory. Inventory model predicts big spreads in slow markets. Neither result would be observed if the underlying securities market provided a perfect hedge. We interpret these mixed results as meaning that the option market maker is able to only imperfectly hedge his positions in the underlying securities market. Our result of insignificant options volume casts doubt on the price discovery argument between stock and option market (Easley, O'Hara, and Srinivas (1998)). Asymmetric information costs in either market are naturally passed to the other market maker's hedgeing and therefore it is unimportant where the informed traders trade.

Available in PDF, EPUB and Kindle. Book excerpt: The analysis of the microstructure of financial markets has been one of the most important areas of research in finance and has allowed scholars and practitioners alike to have a much more sophisticated understanding of the dynamics of price formation in financial markets. Frank de Jong and Barbara Rindi provide an integrated graduate level textbook treatment of the theory and empirics of the subject, starting with a detailed description of the trading systems on stock exchanges and other markets and then turning to economic theory and asset pricing models. Special attention is paid to models explaining transaction costs, with a treatment of the measurement of these costs and the implications for the return on investment. The final chapters review recent developments in the academic literature. End-of-chapter exercises and downloadable data from the book's companion website provide opportunities to revise and apply models developed in the text.
