Available in PDF, EPUB and Kindle. Book excerpt: This paper shows that option trading does not reduce overpricing in the underlying stock market. A popular view in the literature is that options lower short selling cost, therefore, they allow stock prices to better incorporate negative information and opinions. Testing such a hypothesis is challenging because certain variables can drive both option trading and stock pricing, and failure to control for these variables gives rise to endogeneity issues. We develop an instrumental variable for option trading volume and use it to show that exogenous increase in option trading leads to more severe overpricing, which contradicts the existing view. Specifically, the instrumental variable is the distance between two adjacent option strike prices measured as a percentage of the underlying stock price.

Download or read book The Effects of Options Markets on the Underlying Markets written by Brenden James Mason and published by . This book was released on 2018 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three essays in applied financial economics. The unifying theme is the use of financial regulation as quasi-experiments to understand the interrelationship between derivatives and the underlying assets. The first two essays use different quasi-experimental econometric techniques to answer the same research question: how does option listing affect the return volatility of the underlying stock? This question is difficult to answer empirically because being listed on an options exchange is not random. Volatility is one of the dimensions along which the options exchanges make their listing decisions. This selection bias confounds any causal effect that option listing may have. What is more, the options exchanges may list along unobservable dimensions. Such omitted variable bias can also confound any causal effect of option listing. My first essay overcomes these two biases by exploiting the exogenous variation in option listing that is created by the SEC-imposed option listing standards. Specifically, the SEC mandates that a stock must meet certain criteria in the underlying market before it can trade on an options exchange. For example, a stock needs to trade a total of 2.4 million shares over the previous 12 months before it can be listed. Since 2.4 million is an arbitrary number, stocks that are "just above" the 2.4 million threshold will be identical to stocks that are "just below" it, the sole difference being their probability of option listing. Accordingly, I use the 2.4 million threshold as an instrument for option listing in a fuzzy regression discontinuity design. I find that option listing causes a modest decrease in underlying volatility, a result that corroborates many previous empirical studies. My second essay attempts to estimate the effect of option listing for stocks that are "far away from" the 2.4 million threshold. I overcome the aforementioned omitted variable bias by fully exploiting the panel nature of the data. I control for the unobserved heterogeneity across stocks by implementing a two-way fixed effects model. Unlike most previous studies, I control for individual-level fixed effects at the firm level rather than at the industry level. My results show that option listing is associated with a decrease in volatility. Importantly, these results are only statistically significant in a model with firm-level fixed effects; they are insignificant with industry-level fixed effects. My third essay is a policy evaluation of the SEC's Penny Pilot Program, a mandated decrease of the option tick size for various equity options classes. Several financial professionals claimed that this decrease would drive institutional investors out of the exchange-traded options market, channeling them into the opaque, over-the-counter (OTC) options market. I empirically test an implication of this hypothesis: if institutional investors have fled the exchange-traded options market for the OTC market, then it may take longer for information to be impounded into a stock's price. Using the `price delay' measure of Hou and Moskowitz (2005), I test whether stocks become less price efficient as a result of being included in the Penny Pilot Program. I perform this test using firm-level fixed effects on all classes that were included in the program. I confirm these results with synthetic control experiments for the classes included in Phase I of the Penny Pilot Program. Generally, I find no change in price efficiency of the underlying stocks, which suggests that the decrease in option tick size did not materially erode the price discovery that takes place in the exchange-traded equity options market. I also find evidence that the decrease in option tick size caused an increase in short selling for the piloted stocks.

Download or read book Does Option Trading Have a Pervasive Impact on Underlying Stock Prices written by Neil D. Pearson and published by . This book was released on 2007 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of whether and to what extent option trading impacts underlying stock prices has been a focus of intense interest since options began exchange-based trading in 1973. Despite considerable effort, no convincing evidence for a pervasive impact has been produced. A recent strand of theoretical literature predicts that rebalancing by traders who hedge their option positions increases (decreases) underlying stock return volatility when these traders have net written (purchased) option positions. This paper tests this prediction and finds a statistically and economically significant negative relationship between stock return volatility and net purchased option positions of investors who are likely to hedge. Hence, we provide the first evidence for a substantial and pervasive influence of option trading on stock prices.

Universidad de Cantabria. This book was released on 2019-02-15 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Download or read book Does Option Trading Make Underlying Stock Prices More Efficient Evidence from IPO Lockup Expirations written by Li Wang and published by . This book was released on 2014 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well documented that IPO stock prices decline without reversals around lockup expirations, creating a novel setting to examine the impact of option trading on stock price efficiency. I find that optionable IPO stocks' prices experience significant declines prior to lockup expirations, while non-optionable stocks' prices start to decline at and after expiration dates. Delta-adjusted order imbalances in option markets are negative prior to lockup expirations and even more negative when it is hard to borrow in the underlying stock markets. These results provide robust new evidence that derivatives trading helps make the underlying stock market more efficient.

Download or read book How Does Option Listing Affect Underlying Stock Efficiency Evidence from a Duration Model written by Kaouther Jouaber-Snoussi and published by . This book was released on 2015 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: We empirically investigate the effect of option listing on the underlying stock efficiency by examining the stock price duration dynamic and the informed trading activity around option listing. We use univariate tests and extended Log-ACD models that account for liquidity. Despite a significant increase in the price duration, option listing seems not to deteriorate the underlying stock efficiency. The results reject a permanent change in the informed trading activity but suggest a positive intraday seasonal impact. However, this result is not confirmed for low volume stocks. Furthermore, Euronext and Liffe merger in 2002 seems to have an impact on the duration process and the efficiency of underlying stocks.

Download or read book Options Trading Activity and Firm Valuation written by Eduardo S. Schwartz and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the effect of options trading volume on the value of the underlying firm after controlling for other variables that may affect firm value. The volume of options trading might have an effect on firm value because it helps to complete the market (allocational efficiency) and because the options market impounds information faster than the stock market (informational efficiency). We find that firms with more options trading have higher values. This result holds for all sample firms and for the subset of firms with positive options volume.

Download or read book The Price Effect of Option Introductions written by Sorin M. Sorescu and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I examine the effect of option listings on underlying stock prices during 1973 - 1992. In accordance with previous studies, I find that option listings increase stock prices between 1973 and 1980. While some authors attribute this price increase to market completion, I show that this increase is only temporary, and is more likely attributed to market manipulation. As a result of new federal regulations introduced at the end of 1980, I find no evidence of stock price manipulation for options listed between 1981 and 1992. Surprisingly however, during this later period the price effect of option introductions does not merely vanish, but becomes negative, and remains persistent over the 200 trading days following option listings. A longer term negative effect is documented even for options listed prior to 1980, suggesting that the real price effect of option introductions is negative throughout the entire sample period.

Download or read book The Mathematics of Options written by Michael C. Thomsett and published by Springer. This book was released on 2017-08-30 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for the experienced portfolio manager and professional options traders. It is a practical guide offering how to apply options math in a trading world that demands mathematical measurement. Every options trader deals with an array of calculations: beginners learn to identify risks and opportunities using a short list of strategies, while researchers and academics turn to advanced technical manuals. However, almost no books exist for the experienced portfolio managers and professional options traders who fall between these extremes. Michael C. Thomsett addresses this glaring gap with The Mathematics of Options, a practical guide with actionable tools for the practical application of options math in a world that demands quantification. It serves as a valuable reference for advanced methods of evaluating issues of pricing, payoff, probability, and risk. In his characteristic approachable style, Thomsett simplifies complex hot button issues—such as strategic payoffs, return calculations, and hedging options—that may be mentioned in introductory texts but are often underserved. The result is a comprehensive book that helps traders understand the mathematic concepts of options trading so that they can improve their skills and outcomes.
