Real option
Encyclopedia
Real options valuation, also often termed Real options analysis, (ROV or ROA) applies option
valuation techniques
to capital budgeting
decisions. A real option itself, is the right — but not the obligation — to undertake some business decision; typically the option to make, abandon, expand, or contract a capital investment. For example, the opportunity to invest in the expansion of a firm's factory, or alternatively to sell the factory, is a real call
or put option
, respectively.
Real Options, as a discipline, extends from its application in Corporate Finance
, to decision making under uncertainty in general, adapting the techniques developed for financial options
to "real-life" decisions. For example, R&D managers can use Real Options Valuation to help them determine where to best invest their money in research; a non business example might be the decision to join the work force, or rather, to forgo several years of income to attend graduate school
. It thus forces decision makers to be explicit about the assumptions underlying their projections, and for this reason ROV is increasingly employed as a tool in business strategy formulation.
, such as discounted cash flow
(DCF) analysis / net present value
(NPV).
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
higher volatility of the underlying
leads to higher value).
:
However, ROV is distinguished from these approaches in that it takes into account uncertainty about the future evolution of the parameters that determine the value of the project, and management's ability to respond to the evolution of these parameters. It is the combined effect of these that makes ROV technically more challenging than its alternatives. When valuing the real option, the analyst must consider the inputs to the valuation, the valuation method employed, and whether any technical limitations may apply.
. Note though that, in general, while most "real" problems allow for American style exercise at any point (many points) in the project's life and are impacted by multiple underlying variables, the standard methods are limited either with regard to dimensionality, to early exercise, or to both. In selecting a model, therefore, analysts must make a trade off between these considerations; see Option (finance): Model implementation. The model must also be flexible enough to allow for the relevant decision rule to be coded appropriately at each decision point.
Various other methods, aimed mainly at practitioner
s, have been developed for real option valuation. These typically use cash-flow scenarios for the projection of the future pay-off distribution, and are not based on restricting assumptions similar to those that underlie the closed form (or even numeric) solutions discussed. The most recent additions include the Datar–Mathews method
and the Fuzzy Pay-Off Method

In overview:
, for which these were originally developed. The main difference is that the underlying
is often not tradeable - 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

The difficulties:
These issues are addressed via several interrelated assumptions:
of the MIT Sloan School of Management
in 1977. It is interesting to note though, that in 1930, Irving Fisher
wrote explicitly of the "options" available to a business owner (The Theory of Interest, II.VIII). The description of such opportunities as "real options", however, followed on the development of analytical techniques for 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
(University of Cyprus
) has been a leading name for many years, publishing several influential books and academic articles. Other pioneering academics in the field include Professors Eduardo Schwartz
and Michael Brennan
(UCLA Anderson). An academic conference on real options is organized yearly (Annual International Conference on Real Options
).
Amongst others, the concept was "popularized" by Michael J. Mauboussin
, then chief U.S. investment strategist for Credit Suisse First Boston
. He uses real options to explain the gap between how the stock market prices some businesses and the "intrinsic value
" for those businesses. Trigeorgis also has broadened exposure to real options through layman articles in publications such as The Wall Street Journal
. This popularization is such that ROV is now a standard offering in 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 HBR
articles: "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").

. The NPV framework (implicitly) assumes that management is "passive" with regard to their Capital Investment once committed. Analysts usually account for this uncertainty by adjusting the discount rate (e.g. by increasing the cost of capitalCost of capitalThe cost of capital is a term used in the field of financial investment to refer to the cost of a company's funds , or, from an investor's point of view "the shareholder's required return on a portfolio of all the company's existing securities"...
) or the cash flows (using certainty equivalents, or applying (subjective) "haircuts" to the forecast numbers). These methods normally do not properly account for changes in risk over a project's lifecycle and fail to appropriately adapt the risk adjustment. - By contrast, ROV assumes that management is "active" and can modify the project as necessary. ROV models consider "all" future outcomes and management's response to these contingent scenarios. Because management responds to each outcome - i.e. the options are exercisedExercise (options)The owner of an option contract may exercise it, indicating that the financial transaction specified by the contract is to be enacted immediately between the two parties, and the contract itself is terminated...
- the possibility of a (large) negative outcome is reduced (or even eliminated), and /or greater profit is achieved. Risk is therefore reduced or "eliminated" under ROV, and uncertainty is accounted for using the techniques applied to financial optionsOption (finance)In finance, an option is a derivative financial instrument that specifies a contract between two parties for a future transaction on an asset at a reference price.

Limitations
The relevance of Real options, even as a thought framework, may be limited due to organizational and / or technical considerations. When the framework is employed, therefore, the analyst must first ensure that ROV is relevant to the project in question. These considerations are as below.Organizational considerations
Real options are “particularly important for businesses with a few key characteristics”, and may be less relevant otherwise. At the same time the market in question must be one where "change is most evident", and the "source, trends and evolution" in product demand and supply, create the volatility and contingencies discussed above.In overview:
- 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 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 financial position of the business must be such that it has the ability to fund the project as required (i.e. issue shares, absorb further debt and / or use internally generated cash flow); see Financial statement analysisFinancial statement analysisFinancial statement analysis is the process of understanding the risk and profitability of a firm through analysis of reported financial information, particularly annual and quarterly reports....
. Management must also have appropriate access to this capital.
Technical considerations
Limitations as to the use of these models arise due to the contrast between Real Options and financial optionsOption (finance)

The difficulties:
- 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 priceSpot priceThe spot price or spot rate of a commodity, a security or a currency is the price that is quoted for immediate settlement .

(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: Some real options are proprietary (owned or exercisable by a single individual or a company) while others are shared (can be exercised by many parties). 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.

- Option pricing models are built on 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) ArbitrageArbitrageIn economics and finance, arbitrage is the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices...
arguments then allow for the option's price to be estimated today; see Rational pricing: Delta hedging. (c) When hedging of this sort is possible, since delta hedging and risk neutral pricing are mathematically identical, then 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 constant volatility assumption.

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 premium over risk free would be required, invalidating (technically) the risk neutrality assumption.

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, interestingly, 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 practitioners use the "replicating portfolio approach", as opposed to Risk neutral valuation, and modify their models correspondingly. Under this approach, we "replicate" the cash flows on the option by holding a risk free bond and the underlying in the correct proportions. Then, since the value of the option and the portfolio will be identical in the future, they may be equated today, and no discounting is required.
