Return predictability and the real option value of segments

Theory suggests that firm value should include the value of real options; that is, firms have the option to expand more profitable businesses and liquidate less profitable businesses. In a diversified firm, each segment has its own real options. Applying real options theory to a diversified firm at the firm level neglects the value of segment-level options. If investors overlook segment-level options, mispricing will occur. Using data from 1981 to 2013, we find that a hedge portfolio buying diversified firms in the highest decile of the estimated real option value of segments (RVS) and selling those in the lowest RVS decile earns a significant 0.79% size-adjusted monthly return. The hedge returns are more significant for firms whose growth opportunities mainly lie in the more profitable segments. We also find that the predictive power of RVS is stronger for firms with high growth, lower analyst coverage, and stronger corporate governance. Further investigation links improved operating performance to the exercise of segment-level real options.     

Brealey,Myers, and Allen on Real Options

Real options are valuable sources of flexibility that are either inherent in, or can be built into, corporate assets. The value of such options are generally not captured by the standard discounted cash flow (DCF) approach, but can be estimated using a variant of financial option pricing techniques. This article provides an overview of the basics of real option valuation by examining four important kinds of real options:

• 1 The option to make follow‐on investments. Companies often cite “strategic” value when taking on negative‐NPV projects. A close look at the payoffs from such projects reveals call options on follow‐on projects in addition to the immediate cash flows from the projects. Today's investments can generate tomorrow's opportunities.
• 2 The option to wait (and learn) before investing. This is equivalent to owning a call option on the investment project. The call is exercised when the firm commits to the project. But often it's better to defer a positive‐NPV project in order to keep the call alive. Deferral is most attractive when uncertainty is great and immediate project cash flows—which are lost or postponed by waiting—are small.
• 3 The option to abandon. The option to abandon a project provides partial insurance against failure. This is a put option; the put's exercise price is the value of the project's assets if sold or shifted to a more valuable use.
• 4 The option to vary the firm's output or its production methods. Companies often build flexibility into their production facilities so that they can use the cheapest raw materials or produce the most valuable set of outputs. In this case they effectively acquire the option to exchange one asset for another.

The authors also make the point that, in most applications, real‐option valuation methods are a complement to, not a substitute for, the DCF method. Indeed DCF, which is best suited to and usually sufficient for safe investments and “cash cow” assets, is typically the starting point for real‐option analyses. In such cases, DCF is used to generate the values of the “underlying assets”—that is, the projects when viewed without their options or sources of flexibility.     

The Real Options Component and Market Value of Taiwan Technological Companies

Real options valuation has been applied in real investment extensively. However the empirical researches of real options components’ value are seldom studied. This study uses the panel data model to test whether the stock prices of Taiwan listed companies reflect investor’s expectations regarding the value of real options. This article demonstrates that investors cannot ignore the real options components when evaluating stock market value. The results also confirm that the proportion of a firm’s market value not due to assets-in-place is significantly and positively related to the variables of stock beta, skewness of stock returns, size, capital stock, and research and development. In addition, firms with lower firm life cycle have a higher real options value.     

A Fuzzy Set Approach for Generalized CRR Model: An Empirical Analysis of S&;P 500 Index Options

This paper applies fuzzy set theory to the Cox, Ross and Rubinstein (CRR) model to set up the fuzzy binomial option pricing model (OPM). The model can provide reasonable ranges of option prices, which many investors can use it for arbitrage or hedge. Because of the CRR model can provide only theoretical reference values for a generalized CRR model in this article we use fuzzy volatility and fuzzy riskless interest rate to replace the corresponding crisp values. In the fuzzy binomial OPM, investors can correct their portfolio strategy according to the right and left value of triangular fuzzy number and they can interpret the optimal difference, according to their individual risk preferences. Finally, in this study an empirical analysis of S&P 500 index options is used to find that the fuzzy binomial OPM is much closer to the reality than the generalized CRR model.This project has been supported by NSC 93-2416-H-009-024.JEL Classification:     

Information manipulation in equity crowdfunding markets

In digital finance markets, investors can withdraw their non-binding bids within a cooling-off period. As the bids are visible online, we argue that this option can be used to manipulate the information available to investors. Previous research indeed shows that early bids attract later investors and trigger information cascades, thereby enhancing the chances of success of the offerings. Using a dataset of 3564 investment lines, we observe frequent (10.2%) investment withdrawals before the end of the offerings. Platform members invested in 64% and later withdrew from 30% of the offerings listed in their portal, being 1.85 times more likely to withdraw than the average crowdfunding investor. We document that their investments take place predominantly in low-quality offerings and influence the campaign dynamics, increasing the number of subsequent bids.     

Real Options, (Dis)Investment Decision-Making and Accounting Measures of Performance

This paper suggests that a residual income-type measure of performance can be designed which supports optimal investment and disinvestment decision-making in a real options framework involving the options to wait before investing and to abandon. The measure has a number of advantages and disadvantages. Nonetheless, the balance of advantage versus disadvantage for the proposed measure must be set against the inadequacies of other competing measures of performance and associated organisational designs. Even if the measure of performance suggested is not regarded as practically useful, it has another general advantage – it can be used as a benchmark against which to evaluate other performance measures with regard to their support of optimal investment and disinvestment decision-making in a real options framework.

Managerial flexibility and the wealth effect of new product introductions

This paper examines whether investors recognize the value of managerial flexibilities, as proxied by real options, in their valuation of new product introductions. We define a firm’s real options portfolio as the difference between the firm’s market value and its assets in place. A firm’s strategic flexibilities are modeled as the ratio of its real option portfolio to its book value. Using a sample of new product introductions from 1998–2007, we find our real options measure is positively related to announcement period abnormal returns. This result holds after we control for other variables known to be correlated with the announcement effect in previous studies. Our result is robust to alternative measures of real options based on analysts’ earnings expectations and whether a firm has one or multiple segments. In summary, our results suggest that a firm’s perceived strategic and operating flexibilities are an important factor in the valuation of new products.     

Effects of taxation for option writers: an Australian perspective

Writing an option is a taxable event for Australian investors. This method of taxation penalizes investors who hold open short option positions over the tax year end by accelerating their tax liability relative to the timing of the economic gain from writing options. This paper examines the levels of open interest in the Australian Stock Exchange over the change in financial year to determine whether investors time their transactions to avoid this tax acceleration. The results show that level of open interest is lower in the last month of the financial year after controlling for non‐tax determinants of option demand.     

DIVERSIFICATION AND SKEWNESS IN OPTION PORTFOLIOS

Skewness in returns is relevant to option investors. Because options possess positively skewed distributions, the traditional maxim of diversification, which can destroy positive skewness, is not necessarily consistent with investment objectives. The results indicate that the majority of skewness in option portfolios is diversified with a relatively small portfolio size, suggesting a strategy of antidiversification for option investors. Even though the investment performance of options is inferior to stocks on a risk-return basis, the data indicate the suitability of option portfolios in an environment where an investor's utility is measured by the return, risk, and skewness of the return distribution.     

Retail clientele and option returns

Does the retail clientele matter for option returns? By delta-hedging options and trading straddles, thus allowing a focus on volatility, this paper empirically shows that a higher retail trading proportion (RTP) is related to lower option returns. Long-short portfolios involving options on low and high RTP stocks generate significantly positive abnormal returns. The results suggest that retail investors speculate and pay a lottery premium on the expected future volatility, resulting in more expensive options with higher implied volatilities.     

An Empirical Portfolio Perspective on Option Pricing Anomalies

We empirically study the economic benefits of giving investorsaccess to index options in the standard portfolio problem, analyzingboth expected-utility and nonexpected-utility investors in orderto understand who optimally buys and sells options. Using dataon S&P 500 index options, CRRA investors find it alwaysoptimal to short out-of-the-money puts and at-the-money straddles.The option positions are economically and statistically significantand robust to corrections for transaction costs, margin requirements,and Peso problems. Loss-averse and disappointment-averse investorsalso optimally hold short option positions. Only with highlydistorted probability assessments can we obtain positive portfolioweights for puts (cumulative prospect theory and anticipatedutility) and straddles (anticipated utility).     

Empirical Study of Nikkei 225 Options with the Markov Switching GARCH Model

This paper investigates the pricing of Nikkei 225 Options using the Markov Switching GARCH (MSGARCH) model, and examines its practical usefulness in option markets. We assume that investors are risk-neutral and then compute option prices by using Monte Carlo simulation. The results reveal that, for call options, the MSGARCH model with Student’s t-distribution gives more accurate pricing results than GARCH models and the Black–Scholes model. However, this model does not have good performance for put options.     

Derivative Pricing 60 Years before Black–Scholes: Evidence from the Johannesburg Stock Exchange

We obtain daily data for warrants traded on the Johannesburg Stock Exchange between 1909 and 1922, and for a broker's call option quotes on stocks from 1908 to 1911. We use this new data set to test how close derivative prices are to Black–Scholes (1973) prices and to compute profits for investors using a simple trading rule for call options. We examine whether investors exercised warrants optimally and how they reacted to extensions of the warrants' durations. We show that long before the development of the formal theory, investors had an intuitive grasp of the determinants of derivative pricing.     

Bookbuilding and Strategic Allocation

In the bookbuilding procedure, an investment banker solicits bids for shares from institutional investors prior to pricing an equity issue. The banker then prices the issue and allocates shares at his discretion to the investors. We examine the books for 39 international equity issues. We find that the investment banker awards more shares to bidders who provide information in their bids. Regular investors receive favorable allocations, especially when the issue is heavily oversubscribed. The investment banker also favors revised bids and domestic investors.     

The implied Sharpe ratio

In an incomplete market, including liquidly traded European options in an investment portfolio could potentially improve the expected terminal utility for a risk-averse investor. However, unlike the Sharpe ratio, which provides a concise measure of the relative investment attractiveness of different underlying risky assets, there is no such measure available to help investors choose among the different European options. We introduce a new concept—the implied Sharpe ratio—which allows investors to make such a comparison in an incomplete financial market. Specifically, when comparing various European options, it is the option with the highest implied Sharpe ratio that, if included in an investor's portfolio, will improve his expected utility the most. Through the method of Taylor series expansion of the state-dependent coefficients in a nonlinear partial differential equation, we also establish the behaviour of the implied Sharpe ratio with respect to an investor's risk-aversion parameter. In a series of numerical studies, we compare the investment attractiveness of different European options by studying their implied Sharpe ratio.     

Laboratory Evidence on How Managers Intuitively Value Real Growth Options

We asked 82 experienced managers to value, in effect, a set of real options, by taking decisions on invented case studies. The classic Black Scholes model should set an upper bound for rational valuations of these options (since it assumes a risk neutral discount rate, which may be optimistic). The managers valued their options erratically, and generally optimistically, though their responses to changes in moneyness, volatility and maturity tended to be in the 'correct' directions. Oil industry managers over-valued least, relative to Black-Scholes, and Brewery managers most. Questionnaires explored managers' perceptions of the real option parameters encountered in their workplaces.     

On-market share buybacks, exercisable share options and earnings management

Chan et al. (2006b ) suggest that managers might announce a share buyback to manipulate investors’ perceptions and capitalize on the positive price reaction usually associated with the announcement. The incentive to do so is greater when managers have exercisable options. Prior studies document that managers engage in upwards earnings management for opportunistic reasons related to option holdings (Bergstresser and Philippon, 2006). We examine the association between earnings management and exercisable option holdings for buyback firms to investigate if earnings management in the pre‐buyback period is greater for firms with equity incentives to increase share price. Our results, using 138 buybacks over the period 1996–2003, support our prediction. We find that buyback firms with both exercisable options that are in‐the‐money prior to the buyback announcement as well as options that are exercised in the buyback period have higher discretionary current accruals than buyback firms with no exercisable options, unexercised options or with out‐of‐the‐money options. Overall, our results are consistent with buyback firms with exercisable options using earnings management and buyback announcements to maximize option payoffs, and buyback firms without exercisable options signalling undervaluation.     

Bookbuilding with heterogeneous investors

Empirical evidence suggests that better-informed investors in bookbuilt IPOs submit more informative bids and receive better allocations than do investors with less precise information. While the traditional bookbuilding argument accounts for this evidence as better-informed investors being rewarded with more favorable allocations for providing more useful information, the present paper adopts the winner's curse argument and shows that better-informed investors get better allocations by being better able to pick underpriced issues, even though in equilibrium investors' bids fully reveal their information. The paper offers empirical implications that allow the two arguments to be separated.     

Using real options theory to explain patterns in the valuation of research and development expenditures

Real options theory posits that the value of the firm is a combination of the value generated by the assets in place and the value of the option to invest in the future. It is based on the idea that many decisions are difficult to reverse, and valuing the outcome of these decisions is more complicated than estimating the present value of future cash flows. R&D activities often generate real options due to the nature of these activities, and examining the valuation of R&D expenditures through the lens of real options theory can help explain differing results documented in both the R&D and value relevance of earnings and book value literatures. Numerous studies have documented that the stock market positively values R&D expenditures; however, recent work has raised questions about whether this positive relation occurs across firms reporting both profits and losses. Consistent with real options theory, I find that the negative coefficient on the R&D expenditures of profitable firms documented by prior studies only exists for low growth firms. In addition, for all R&D firms experiencing high sales growth, the market places a lower value on assets in place and a higher value on R&D expenditures.
