''Identifying real options''
Duke University, 2002. A real option itself, is the right—but not the obligation—to undertake certain business initiatives, such as deferring, abandoning, expanding, staging, or contracting a
capital investment project.
For example, real options valuation could examine the opportunity to invest in the expansion of a firm's factory and the alternative option to sell the factory.

Real options are most valuable when uncertainty is high; management has significant flexibility to change the course of the project in a favorable direction and is willing to exercise the options.
Scope
Real options are generally distinguished from conventional financial options in that they are not typically traded as securities, and do not usually involve decisions on an underlying asset that is traded as a financial security. A further distinction is that option holders here, i.e. management, can directly influence the value of the option's

project; whereas this is not a consideration regarding the underlying security of a financial option. Moreover, management cannot measure uncertainty in terms of
volatility, and must instead rely on their perceptions of uncertainty. Unlike financial options, management must also create or discover real options, and such creation and discovery process comprises an entrepreneurial or business task.
Real options analysis, as a discipline, extends from its application in

Options relating to project size
Where the project's scope is uncertain, flexibility as to the size of the relevant facilities is valuable, and constitutes optionality.
*Option to expand: Here the project is built with capacity in excess of the expected level of output so that it can produce at higher rates if needed. Management then has the option (but not the obligation) to expand – i.e.
exercise the option – should conditions turn out to be favourable. A project with the option to expand will cost more to establish, the excess being the

Options relating to project life and timing
Where there is uncertainty as to when, and how, business or other conditions will eventuate, flexibility as to the timing of the relevant project(s) is valuable, and constitutes optionality.

The firm will market and develop the product only if the present value of the expected cash flows from the product sales exceeds the cost of development.

*Sequencing options: This option is related to the initiation option above, although entails flexibility as to the timing of more than one inter-related projects: the analysis here is as to whether it is advantageous to implement these
sequentially or
in parallel. Here, observing the outcomes relating to the first project, the firm can resolve some of the uncertainty relating to the venture overall. Once resolved, management has the option to proceed or not with the development of the other projects. If taken in parallel, management would have already spent the resources and the value of the option not to spend them is lost. The sequencing of projects is an important issue in

Options relating to project operation
Management may have flexibility relating to the product produced and/or the
process used in manufacture. As in the preceding cases, this flexibility increases the value of the project, corresponding in turn, to the "premium" paid for the real option.
*Output mix options: The option to produce different outputs from the same facility is known as an output mix option or product flexibility. These options are particularly valuable in industries where demand is volatile or where quantities demanded in total for a particular good are typically low, and management would wish to change to a different product quickly if required.
*Input mix options: An input mix option – process flexibility – allows management to use different inputs to produce the same output as appropriate. For example, a farmer will value the option to switch between various feed sources, preferring to use the cheapest acceptable alternative. An

Intensity options.

Even when employed, however, these latter methods do not normally properly account for changes in risk over the project's lifecycle and hence fail to appropriately adapt the risk adjustment.

''Calculating value during uncertainty''
IBM Institute for Business Value
By contrast, ROV assumes that management is "active" and can "continuously" respond to market changes. Real options consider "all" scenarios (or
"states") and indicate the best corporate action in each of these
contingent events.
Because management adapts to each negative outcome by decreasing its exposure and to positive scenarios by scaling up, the firm benefits from uncertainty in the underlying market, achieving a lower variability of profits than under the commitment/NPV stance. The contingent nature of future profits in real option models is captured by employing the techniques developed for
financial options in the literature on
contingent claims analysis. Here the approach, known as risk-neutral valuation, consists in
adjusting the probability distribution for risk consideration, while discounting at the risk-free rate. This technique is also known as the "martingale" approach, and uses a
risk-neutral measure

Given these different treatments, the real options value of a project is typically higher than the NPV – and the difference will be most marked in projects with major flexibility, contingency, and volatility.
As for
financial options, a higher
volatility of the underlying leads to a higher value. An application of real options valuation in the Philippine banking industry exhibited that increased levels of income volatility may adversely affect option values on the loan portfolio, when the presence of information asymmetry is considered. In this case, increased volatility may limit the value of an option. Part of the criticism and subsequently slow adoption of real options valuation in practice and academia stems from the generally higher values for underlying assets these functions generate. However, studies have shown that these models are reliable estimators of underlying asset value, when input values are properly identified.
Options based valuation
Although there is much similarity between the modelling of real options and
financial options,
ROV is distinguished from the latter, in that it takes into account uncertainty about the future evolution of the parameters that determine the value of the project, ''coupled with'' management's ability to respond to the evolution of these parameters.
[Jenifer Piesse and Alexander Van de Putte. (2004)]
"Volatility estimation in Real Options"
8th Annual International Conference on Real Options It is the combined effect of these that makes ROV technically more challenging than its alternatives.
When valuing the real option, the analyst must therefore consider the inputs to the valuation, the valuation method employed, and whether any technical limitations may apply. Conceptually, valuing a real option looks at the premium between inflows and outlays for a particular project. Inputs to the value of a real option (time, discount rates, volatility, cash inflows and outflows) are each affected by the terms of business, and external environmental factors that a project exists in. Terms of business as information regarding ownership, data collection costs, and patents, are formed in relation to political, environmental, socio-cultural, technological, environmental and legal factors that affect an industry. Just as terms of business are affected by external environmental factors, these same circumstances affect the volatility of returns, as well as the discount rate (as firm or project specific risk). Furthermore, the external environmental influences that affect an industry affect projections on expected inflows and outlays.
Valuation inputs
Given the similarity in valuation approach, the inputs required for modelling the real option correspond, generically, to those required for a financial option valuation.
The specific application, though, is as follows:

the fuzzy pay-off method for real option valuation, fuzzy pay-off method,

By contrast, methods focusing on, for example, real option valuation in engineering design may be more sophisticated. These include analytics based on decision rules, which merge physical design considerations and management decisions through an intuitive "if-then-else" statement e.g., ''if'' demand is higher than a certain production capacity level, ''then'' expand existing capacity, ''else'' do nothing; this approach can be combined with advanced mathematical optimization methods like stochastic programming and Robust optimization, robust optimisation to find the optimal design and decision rule variables. A more recent approach reformulates the real option problem as a data-driven Markov decision process, and uses advanced machine learning like deep reinforcement learning to evaluate a wide range of possible real option and design implementation strategies, well suited for complex systems and investment projects.
These help quantify the value of flexibility engineered early on in system designs and/or irreversible investment projects. The methods help rank order flexible design solutions relative to one another, and thus enable the best real option strategies to be exercised cost effectively during operations. These methods have been applied in many use cases in aerospace, defense, energy, transport, space, and water infrastructure design and planning.
Limitations
The relevance of Real options, even as a thought framework, may be limited due to market, organizational and / or technical considerations.
[Ronald Fink]
Reality Check for Real Options
''CFO Magazine'', September, 2001 When the framework is employed, therefore, the analyst must first ensure that ROV is relevant to the project in question. These considerations are as follows.
Market characteristics
As discussed #Applicability of standard techniques, above, the market and environment underlying the project must be one where "change is most evident", and the "source, trends and evolution" in product demand and supply, create the "flexibility, contingency, and volatility"
which result in optionality. Without this, the NPV framework would be more relevant.
Organizational considerations
Real options are "particularly important for businesses with a few key characteristics",
and may be less relevant otherwise.
In overview, it is important to consider the following in determining that the RO framework is applicable:
#Corporate strategy has to be adaptive to contingent events. Some corporations face organizational rigidities and are unable to react to market changes; in this case, the NPV approach is appropriate.
# Practically, the business must be positioned such that it has appropriate information flow, and opportunities to act. This will often be a market leader and / or a firm enjoying economy of scale, economies of scale and scope.
# Management must understand options, be able to identify and create them, and appropriately exercise them.
This contrasts with business leaders focused on maintaining the status quo and / or near-term accounting earnings.
# The Statement of Financial Position, financial position of the business must be such that it has the ability to fund the project as, and when, required (i.e. issue shares, absorb further debt and / or use internally generated cash flow); see Financial statement analysis. Management must, correspondingly, have appropriate access to this capital.
# Management must be in the position to exercise, in so far as some real options are proprietary (owned or exercisable by a single individual or a company) while others are shared (can (only) be exercised by many parties).
Technical considerations
Limitations as to the use of these models arise due to the contrast between Real Options and
financial options, for which these were originally developed.

The main difference is that the
underlying
In finance, a derivative is a contract between a buyer and a seller. The derivative can take various forms, depending on the transaction, but every derivative has the following four elements:
# an item (the "underlier") that can or must be bou ...
is often not tradable – e.g. the factory owner cannot easily sell the factory upon which he has the option. Additionally, the real option itself may also not be tradeable – e.g. the factory owner cannot sell the right to extend his factory to another party, only he can make this decision (some real options, however, can be sold, e.g., ownership of a vacant lot of land is a real option to develop that land in the future). Even where a market exists – for the underlying or for the option – in most cases there is limited (or no) market liquidity. Finally, even if the firm can actively adapt to market changes, it remains to determine the right paradigm to discount future claims
The difficulties, are then:
# As above, data issues arise as far as estimating key model inputs. Here, since the value or price of the underlying cannot be (directly) observed, there will always be some (much) uncertainty as to its value (i.e. spot price) and Volatility (finance), volatility (further complicated by uncertainty as to management's actions in the future).
# It is often difficult to capture the rules relating to exercise, and consequent actions by management. Further, a project may have a portfolio of embedded real options, some of which may be mutually exclusive.
# Theoretical difficulties, which are more serious, may also arise.

Does Risk-Neutral Valuation Mean that Investors Are Risk-Neutral?

::*Option pricing models are built on Rational pricing#Options, rational pricing logic. Here, essentially: (a) it is presupposed that one can create a "hedged portfolio" comprising one option and "delta" shares of the underlying. (b) Arbitrage arguments then allow for the option's price to be estimated today; see . (c) When hedging of this sort is possible, since delta hedging and risk neutral pricing are ''mathematically'' identical, then Rational pricing#Risk neutral valuation, risk neutral valuation may be applied, as is the case with most option pricing models. (d) Under ROV however, the option and (usually) its underlying are clearly not traded, and forming a hedging portfolio would be difficult, if not impossible.
::*Standard option models: (a) Assume that the risk characteristics of the underlying do not change over the life of the option, usually expressed via a Black–Scholes#Model assumptions, constant volatility assumption. (b) Hence a standard, risk free rate may be applied as the discount window, discount rate at each decision point, allowing for risk neutral valuation. Under ROV, however: (a) managements' actions actually change the risk characteristics of the project in question, and hence (b) the Required rate of return could differ depending on what state was realised, and a Capital asset pricing model#Asset-specific required return, premium over risk free would be required, invalidating (technically) the risk neutrality assumption.
These issues are addressed via several interrelated assumptions:
# As discussed Real options analysis#Valuation inputs, above, the data issues are usually addressed using a simulation of the project, or a listed proxy. Various new methods – see for example #Valuation methods, those described above – also address these issues.
# Also Real options analysis#Valuation methods, as above, specific exercise rules can often be accommodated by coding these in a bespoke binomial options pricing model, binomial tree; see:.
# The theoretical issues:
::*To use standard option pricing models here, despite the difficulties relating to rational pricing, practitioners adopt the Legal fiction, "fiction" that the real option and the underlying project are both traded: the so called, Marketed Asset Disclaimer (MAD) approach. Although this is a strong assumption, it is pointed out that a similar fiction in fact underpins standard NPV / DCF valuation (and using simulation as above). See: and.
::*To address the fact that changing characteristics invalidate the use of a constant discount rate, some analysts use the "Rational pricing#The replicating portfolio, replicating portfolio approach", as opposed to Rational pricing#Risk neutral valuation, Risk neutral valuation, and modify their models correspondingly. Under this approach, (a) we "replicate" the cash flows on the option by holding a risk free bond and the underlying in the correct proportions. Then, (b) since the cash flows of the option and the portfolio will ''always'' be identical, by arbitrage arguments their values may (must) be equated ''today'', and (c) ''no'' discounting is required. (For an alternative, modifying Black-Scholes, see:.)
History
Whereas business managers have been making capital investment decisions for centuries, the term "real option" is relatively new, and was coined by Professor Stewart Myers of the MIT Sloan School of Management in 1977. In 1930, Irving Fisher wrote explicitly of the "options" available to a business owner (''Irving Fisher#Selected publications, The Theory of Interest''
II.VIII
. The description of such opportunities as "real options", however, followed on the development of analytical techniques for Option (finance), financial options, such as Black–Scholes in 1973. As such, the term "real option" is closely tied to these option methods.
Real options are today an active field of academic research. Professor Lenos Trigeorgis has been a leading name for many years, publishing several influential books and academic articles. Other pioneering academics in the field include Professors Michael Brennan (finance), Michael Brennan, Eduardo Schwartz, Avinash Dixit and Robert Pindyck (the latter two, authoring the pioneering text in the discipline). An academic conference on real options is organized yearly ( Annual International Conference on Real Options).
Amongst others, the concept was "popularized" by Michael Mauboussin, Michael J. Mauboussin, then chief U.S. investment strategist for Credit Suisse First Boston.[Michael J. Mauboussin, Credit Suisse First Boston, 1999]
''Get Real: Using Real Options in Security Analysis''
/ref> He uses real options to explain the gap between how the stock market prices some businesses and the "Intrinsic value (finance), intrinsic value" for those businesses. Trigeorgis also has broadened exposure to real options through layman articles in publications such as The Wall Street Journal.[Lenos Trigeorgis, Rainer Brosch and Han Smit]
''Stay Loose''
copyright 2009 Dow Jones & Company. This popularization is such that ROV is now a standard offering in Master of Finance, postgraduate finance degrees, and often, even in MBA curricula at many Business Schools.
Recently, real options have been employed in business strategy

, both for valuation purposes and as a conceptual framework. The idea of treating strategic investments as options was popularized by Timothy Luehrman in two Harvard Business Review, HBR articles:[Timothy Luehrman: "Investment Opportunities as Real Options: Getting Started on the Numbers". ''Harvard Business Review'' 76, no. 4 (July – August 1998): 51–67.; "Strategy as a Portfolio of Real Options". ''Harvard Business Review'' 76, no. 5 (September–October 1998): 87-99.] "In financial terms, a business strategy is much more like a series of options, than a series of static cash flows". Investment opportunities are plotted in an "option space" with dimensions "volatility" & value-to-cost ("NPVq").
Luehrman also co-authored with William Teichner a Harvard business school cases, Harvard Business School case study, ''Arundel Partners: The Sequel Project'', in 1992, which may have been the first business school case study to teach ROV.[Timothy A. Luehrman and William A. Teichner]
"Arundel Partners: The Sequel Project."
''Harvard Business School Publishing'' case no. 9-292-140 (1992) Reflecting the Mainstream economics, "mainstreaming" of ROV, Professor Robert C. Merton discussed the essential points of Arundel in his Nobel Prize Nobel Prize#Nobel lecture, Lecture in 1997.[Robert Merton, Nobel Prize#Nobel lecture, Nobel Lecture]
''Applications of Option-Pricing Theory: Twenty-Five Years Later''
Pages 107, 115; reprinted: ''American Economic Review'', American Economic Association, vol. 88(3), pages 323–49, June. Arundel involves a group of investors that is considering acquiring the sequel rights to a portfolio of yet-to-be released feature films. In particular, the investors must determine the value of the sequel rights before any of the first films are produced. Here, the investors face two main choices. They can produce an original movie and sequel at the same time ''or'' they can wait to decide on a sequel after the original film is released. The second approach, he states, provides the option ''not'' to make a sequel in the event the original movie is not successful. This real option has economic worth and can be valued monetarily using an option-pricing model. See Option (filmmaking).
