Information about Real Option
Real Options Analysis involves applying the mathematical techniques found in financial options to assess the best course of action to be taken when faced with a real-life decision. For example, R&D managers can use Real Options Analysis to help them determine where to best invest their money in research. It can be used in conjunction with Monte Carlo analysis.
The distinctive feature of this technique is that it takes into account uncertainty about the future evolution of the parameters that determine the value of the project, and managements ability to respond to the evolution of these parameters. The uncertainty is modeled as the volatility of the project value, and managements ability to respond is modeled as an option to contract (an American put option), abandon (also an American put), expand or extend the project (both American call options). For real world projects, often also switching options, composite options or rainbow options are required, which makes a real options analysis technically more difficult than its alternatives. An additional technical difficulty is in estimating the volatility of the project.
Because real options analysis takes into account responding to uncertainty, the real options value of a project is always higher than the net present value, especially in projects with huge uncertainties (higher volatility of the underlying leads to higher value of an option). This is because net present value, which is still the most frequently used technique to date, can only model responding to uncertainty by using precommitted management decisions to mutually exclusive scenarios, and then equating total project value to the scenario that has the highest value.
The technique does involve attempting to predict the future, and as such the quality of the output will only ever be as good as the quality of the inputs, which by their nature are sketchy. This is also valid for net present value analysis, but this technique does not require volatility information. Opinion is therefore divided as to whether Real Options Analysis provides genuinely useful information to real-world practitioners.
In corporate finance, real options analysis applies put option and call option valuation techniques to capital budgeting decisions.[1]
A real option is the right, but not the obligation, to undertake some business decision, typically the option to make a capital investment. For example, the opportunity to invest in the expansion of a firm's factory is a real option. In contrast to financial options a real option is not tradeable—e.g. the factory owner cannot sell the right to extend his factory to another party, only he can make this decision. The terminology "real option" is relatively new, whereas business operators have been making capital investment decisions for centuries. However the description of such opportunities as real options has occurred at the same time as thinking about such decisions in new, more analytically-based, ways. As such the terminology "real option" is closely tied to these new methods. The term "real option" was coined by Professor Stewart Myers at the MIT Sloan School of Management.
Additionally, with real option analysis, uncertainty inherent in investment projects is usually accounted for by risk-adjusting probabilities (a technique known as the equivalent martingale approach). Cash flows can then be discounted at the risk-free rate. With regular DCF analysis, on the other hand, this uncertainty is accounted for by adjusting the discount rate (using e.g. the cost of capital) or the cash flows (using certainty equivalents). These methods normally do not properly account for changes in risk over a project's lifecycle and fail to appropriately adapt the risk adjustment. More importantly, the real options approach forces decision makers to be more explicit about the assumptions underlying their projections.
This kind of option is not a derivative instrument, but an actual tangible option (in the sense of "choice") that a business may gain by undertaking certain endeavors. For example, by investing in a project or property, a company may have the real option of expanding, downsizing, or abandoning other projects in the future. Other examples of real options may be opportunities for research and development, mergers and acquisitions, licensing and film options.
These are called "real options" because they pertain to physical or tangible assets, such as equipment, rather than financial instruments. Taking into account real options can greatly affect the valuation of potential investments. However, valuation methods, such as Net present value (NPV), do not include the benefits that real options might provide.
Generally, the most widely used methods are: Closed form solutions, partial differential equations and the binomial lattices. In business strategy, Real Options have been advanced by the construction of option space, where volatility is compared with value-to-cost, NPVq.
