Valuation of American Futures Options: Theory and Empirical Tests
Published: 3/1986, Volume: 41, Issue: 1 | DOI: 10.1111/j.1540-6261.1986.tb04495.x | Cited by: 129
ROBERT E. WHALEY
This paper reviews the theory of futures option pricing and tests the valuation principles on transaction prices from the S&P 500 equity futures option market. The American futures option valuation equations are shown to generate mispricing errors which are systematically related to the degree the option is in‐the‐money and to the option's time to expiration. The models are also shown to generate abnormal risk‐adjusted rates of return after transaction costs. The joint hypothesis that the American futures option pricing models are correctly specified and that the S&P 500 futures option market is efficient is refuted, at least for the sample period January 28, 1983 through December 30, 1983.

U.S. exchange‐traded stock options are exercisable before expiration. While put options should frequently be exercised early to earn interest, they are not. In this paper, we derive an early exercise decision rule and then examine actual exercise behavior during the period January 1996 through September 2008. We find that more than 3.96 million puts that should have been exercised early remain unexercised, representing over 3.7% of all outstanding puts. We also find that failure to exercise cost put option holders $1.9 billion in forgone interest income and that this interest is systematically captured by market makers and proprietary firms.
The Value of Wildcard Options

Wildcard options are embedded in many derivative contracts. They arise when the settlement price of the contract is established before the time at which the wildcard option holder must declare his intention to make or accept delivery and the exercise of the wildcard option closes out the underlying asset position. This paper provides a simple method for valuing wildcard options and illustrates the technique by valuing the sequence of wildcard options embedded in the S&P 100 index (OEX) option contract. The results show that wildcard options can account for an economically significant fraction of OEX option value.
S&P 100 Index Option Volatility

CAMPBELL R. HARVEY, ROBERT E. WHALEY
Using transaction data on the S&P 100 index options, we study the effect of valuation simplifications that are commonplace in previous research on the timeseries properties of implied market volatility. Using an American‐style algorithm that accounts for the discrete nature of the dividends on the S&P 100 index, we find that spurious negative serial correlation in implied volatility changes is induced by nonsimultaneously observing the option price and the index level. Negative serial correlation is also induced by a bid/ask price effect if a single option is used to estimate implied volatility. In addition, we find that these same effects induce spurious (and unreasonable) negative cross‐correlations between the changes in call and put implied volatility.
Intraday Price Change and Trading Volume Relations in the Stock and Stock Option Markets

JENS A. STEPHAN, ROBERT E. WHALEY
This study investigates intraday relations between price changes and trading volume of options and stocks for a sample of firms whose options traded on the CBOE during the first quarter of 1986. After purging the price change series of the effects of bid/ask spreads, multivariate time‐series analysis is used to estimate the lead/lag relation between the price changes in the option and stock markets. The results indicate that price changes in the stock market lead the option market by as much as fifteen minutes. The analysis of trading volume indicates that the stock market lead may be even longer.
An Anatomy of the “S&P Game”: The Effects of Changing the Rules

MESSOD D. BENEISH, ROBERT E. WHALEY
This study analyzes the effects of changes in S&P 500 index composition from January 1986 through June 1994, a period during which Standard and Poor's began its practice of preannouncing changes five days beforehand. The new announcement practice has given rise to the “S&P game” and has altered the way stock prices react. We find that prices increase abnormally from the close on the announcement day to the close on the effective day. The overall increase is greater than under the old announcement policy although part of the increase reverses after the stock is included in the index.
One Market? Stocks, Futures, and Options During October 1987

ALLAN W. KLEIDON, ROBERT E. WHALEY
We provide new evidence regarding the degree of integration among markets for stocks, futures and options prior to and during the October 1987 market crash. Where previous analyses have resulted in recommendations for the implementation of circuit breakers, the coordination of margin requirements across markets, and changes in regulatory jurisdiction, our analysis indicates that delinkage between markets during the crash was primarily caused by an antiquated mechanism for processing stock market orders. The results suggest that market integration may be better served by efficient order execution than by further restricting markets.To a large extent, the problems of mid‐October can be traced to the failure of these market segments [stocks, stock index futures, and stock options] to act as one. (Report of the Presidential Task Force [Brady Report] (1988, Executive Summary, p. vi)).
Hedge Fund Risk Dynamics: Implications for Performance Appraisal

NICOLAS P.B. BOLLEN, ROBERT E. WHALEY
Accurate appraisal of hedge fund performance must recognize the freedom with which managers shift asset classes, strategies, and leverage in response to changing market conditions and arbitrage opportunities. The standard measure of performance is the abnormal return defined by a hedge fund's exposure to risk factors. If exposures are assumed constant when, in fact, they vary through time, estimated abnormal returns may be incorrect. We employ an optimal changepoint regression that allows risk exposures to shift, and illustrate the impact on performance appraisal using a sample of live and dead funds during the period January 1994 through December 2005.

This paper provides simple, analytic approximations for pricing exchange‐traded American call and put options written on commodities and commodity futures contracts. These approximations are accurate and considerably more computationally efficient than finite‐difference, binomial, or compound‐option pricing methods.

This paper examines the relation between net buying pressure and the shape of the implied volatility function (IVF) for index and individual stock options. We find that changes in implied volatility are directly related to net buying pressure from public order flow. We also find that changes in implied volatility of S&P 500 options are most strongly affected by buying pressure for index puts, while changes in implied volatility of stock options are dominated by call option demand. Simulated delta‐neutral option‐writing trading strategies generate abnormal returns that match the deviations of the IVFs above realized historical return volatilities.
Implied Volatility Functions: Empirical Tests

Bernard Dumas, Jeff Fleming, Robert E. Whaley
Derman and Kani (1994), Dupire (1994), and Rubinstein (1994) hypothesize that asset return volatility is a deterministic function of asset price and time, and develop a deterministic volatility function (DVF) option valuation model that has the potential of fitting the observed cross section of option prices exactly. Using S&P 500 options from June 1988 through December 1993, we examine the predictive and hedging performance of the DVF option valuation model and find it is no better than an ad hoc procedure that merely smooths Black–Scholes (1973) implied volatilities across exercise prices and times to expiration.

The development of asset pricing models that rely on instrumental variables together with the increased availability of easily‐accessible economic time‐series have renewed interest in predicting security returns. Evaluating the significance of these new research findings, however, is no easy task. Because these asset pricing theory tests are not independent, classical methods of assessing goodness‐of‐fit are inappropriate. This study investigates the distribution of the maximal when k of m regressors are used to predict security returns. We provide a simple procedure that adjusts critical values to account for selecting variables by searching among potential regressors.
Mean Reversion of Standard & Poor's 500 Index Basis Changes: Arbitrage‐induced or Statistical Illusion?

MERTON H. MILLER, JAYARAM MUTHUSWAMY, ROBERT E. WHALEY
Mean reversion in stock index basis changes has been presumed to be driven by the trading activity of stock index arbitragers. We propose here instead that the observed negative autocorrelation in basis changes is mainly a statistical illusion, arising because many stocks in the index portfolio trade infrequently. Even without formal arbitrage, reported basis changes would appear negatively autocorrelated as lagging stocks eventually trade and get updated. The implications of this study go beyond index arbitrage, however. Our analysis suggests that spurious elements may creep in whenever the price‐change or return series of two securities or portfolios of securities are differenced.

Theory suggests that reputations allow nonanonymous markets to attenuate adverse selection in trading. We identify instances in which New York Stock Exchange (NYSE) stocks experience trading floor relocations. Although specialists follow the stocks to their new locations, most brokers do not. We find a discernable increase in liquidity costs around a stock's relocation that is larger for stocks with higher adverse selection and greater broker turnover. We also find that floor brokers relocating with the stock obtain lower trading costs than brokers not moving and brokers beginning trading post‐move. Our results suggest that reputation plays an important role in the NYSE's liquidity provision process.
Asset Price Volatility, Bubbles, and Process Switching

Evidence of excess volatilities of asset prices compared with those of market fundamentals is often attributed to speculative bubbles. This study demonstrates that bubbles could in theory lead to excess volatility, but it shows that certain variance bounds tests preclude bubbles as an explanation. The evidence ought to be attributed to model misspecification or inappropriate statistical tests. One important misspecification occurs if a researcher incorrectly specifies the time series properties of market fundamentals. A bubble‐free example economy characterized by a potential switch in government policies produces asset prices that would appear, to an unwary researcher, to contain bubbles.

In its response to the 1975 Congressional mandate to implement a national market system for financial securities, the Securities and Exchange Commission (SEC) initially exempted the option market. Recent dramatic changes in the structure of the option market prompted the SEC to revisit this issue. We examine a sample of actively traded, multiply listed equity options to ask whether this market's characteristics appear consistent with the goals of producing economically efficient transactions and facilitating “best execution.” We find marked changes between June 2000, when quotes are often ignored, and January 2002, when the market more closely resembles a national market.
Can Brokers Have It All? On the Relation between Make‐Take Fees and Limit Order Execution Quality

We identify retail brokers that seemingly route orders to maximize order flow payments, by selling market orders and sending limit orders to venues paying large liquidity rebates. Angel, Harris, and Spatt argue that such routing may not always be in customers’ best interests. For both proprietary limit order data and a broad sample of trades from TAQ, we document a negative relation between several measures of limit order execution quality and rebate/fee level. This finding suggests that order routing designed to maximize liquidity rebates does not maximize limit order execution quality and thus brokers cannot have it all.
A Theory of Capital Structure Relevance under Imperfect Information

ROBERT HEINKEL
Firms raise debt and equity capital to finance a positive net present value project in perfectly competitive capital markets; firm insiders know the function generating the random firm cash flow but potential capital suppliers do not. Taking into account the incentives of insiders to misrepresent their firm type, capital suppliers attempt to design financing mixes of debt and equity that eliminate the adverse incentives of insiders and correctly price securities. Necessary conditions for a costless separating equilibrium are developed to show that the amount of debt used by a firm is monotonically related to its unobservable true value.

The Meaning of Internal Rates of Return

ROBERT DORFMAN
Nearly one hundred years after Irving Fisher' persuasive argument that net present value is the fundamental criterion for appraising investment projects, businessmen and bankers continue to consider the internal rate of return. Business practice is justified in some circumstances. It has long been recognized that a firm will grow asymptotically at a rate equal to the largest real positive root of an individual project' rate of return equation if the net cash flows are continually reinvested in projects of the same type. That same root also controls the firm' asymptotic growth rate if any fixed proportion of the cash flows is reinvested. The other roots of the equation are important also, since the stability of the firm' growth path depends on them.

ROBERT TREZEVANT
This study tests the joint prediction of the substitution effect and the tax exhaustion hypothesis that an increase in non‐debt tax shields leads to a decrease in leverage. Controls are introduced for the debt securability effect, the pecking order theory of financing, and the probability of losing tax shields. Using the relationship between changes in investment tax shields and changes in debt tax shields of firms in response to the Economic Recovery Tax Act of 1981, strong empirical support is found for predictions based on the substitution effect and the tax exhaustion hypothesis.

ROBERT JARROW
Under heterogeneous expectations, the mean–variance model of capital market equilibrium is employed to determine the effect restricting short sales has on equilibrium asset prices. Two equivalent markets differing only with respect to short sale restrictions are compared. It is shown that, in general, risky asset prices can either rise or fall due to short sale constraints. However, under a homogeneity of beliefs for the covariance matrix of future prices, short sale constraints will only increase risky asset prices.

This study examines the behavior of laboratory markets in which two uninformed market makers compete to trade with heterogeneously informed investors. The data provide three main results. First, market makers set quotes to protect against adverse selection and to control inventory. Second, when investors are less well‐informed, their trades are less reliable measures of their information, and market makers respond to those trades with greater skepticism. Third, errors in market makers' reactions to trades cause the time‐series behavior of quotes and prices to depend on the information environment in ways beyond those captured in extant theory.

THE PRICING OF OPTIONS WITH STOCHASTIC DIVIDEND YIELD

Robert Geske
A formula is derived in discrete time for pricing options when the underlying stock has a stochastic dividend yield. The result implies that regarding the dividend yield as certain when it is not results in misestimation of the variance of the underlying stock. Comparative statics indicate that this adjustment could diminish a bias of the Black‐Scholes model. This model systematically underprices deep‐out‐of‐the‐money options. A numerical example demonstrates that this stochastic adjustment may be more important for longer‐lived options and warrants.
The Relationship between Arbitrage and First Order Stochastic Dominance

ROBERT JARROW
This paper joins together two fields of research in financial economics. The first field studies stochastic dominance, while the second field studies arbitrage pricing. The two fields are linked together through the derivation and the proof of a characterization theorem. The characterization theorem gives necessary and sufficient conditions for the existence of arbitrage opportunities in terms of the existence of two assets, one of which first order stochastically dominates the other and the price of a particular contingent claim. Examples are provided to demonstrate the theorem's content.

Robert M. Conroy, Kenneth M. Eades, Robert S. Harris
We study the pricing effects of dividend and earnings announcements by taking advantage of the unique setting in Japan where managers simultaneously announce the current year's dividends and earnings as well as forecasts of next year's dividends and earnings. Defining surprises as deviations from analysts' forecasts, we find that share price reactions are significantly affected by earnings surprises, especially management forecasts of next year's earnings. The information content of dividends is marginal and is restricted to announcements of next year's dividends. Consistent with Modigliani and Miller's dividend irrelevance proposition, current dividend surprises have no material impact on stock prices in Japan.
The Effects of Stock Splits on Bid‐Ask Spreads

ROBERT M. CONROY, ROBERT S. HARRIS, BRUCE A. BENET
This paper examines the effects of stock splits on bid‐ask spreads for NYSE‐listed companies. Percentage spreads increase after splits, representing a liquidity cost to investors. These spread increases are directly related to decreases in share prices following splits and can explain part, but not all, of the observed increase in return variability after splits. The evidence thus suggests a liquidity cost of stock splits that must be weighed against any other perceived benefits of splits. Such a liquidity cost may validate that stock splits are a signal of favorable information about the firm.
