Many projects involve spending money to buy or build a productive asset. Spending money to exploit such a business opportunity is analogous to exercising an option on, for example, a share of stock. The present value of the asset built or acquired corresponds to the stock price S. Finally, the time value of money is given in both cases by the risk-free rate of return r f.

By pricing an option using values for these variables generated from our project, we learn more about the value of the project than a simple discounted-cash-flow analysis would tell us. Traditional DCF methods would assess this opportunity by computing its net present value. NPV is the difference between how much the operating assets are worth their present value and how much they cost:. When NPV is positive, the corporation will increase its own value by making the investment.

When NPV is negative, the corporation is better off not making the investment. At that time, either. To reconcile the two completely, we need only observe that when NPV is negative, the corporation will not invest, so the project value is effectively zero just like the option value rather than negative.

In short, both approaches boil down to the same number and the same decision. Conventional NPV and option value are identical when the investment decision can no longer be deferred. This common ground between NPV and option value has great practical significance. It means that corporate spreadsheets set up to compute conventional NPV are highly relevant for option pricing. Any spreadsheet that computes NPV already contains the information necessary to compute S and X , which are two of the five option-pricing variables. Accordingly, executives who want to begin using option pricing need not discard their current DCF-based systems.

When do NPV and option pricing diverge? When the investment decision may be deferred. The possibility of deferral gives rise to two additional sources of value. First, we would always rather pay later than sooner, all else being equal, because we can earn the time value of money on the deferred expenditure. Specifically, the value of the operating assets we intend to acquire may change. If their value goes down, we might decide not to acquire them. That also is fine very good, in fact because, by waiting, we avoid making what would have turned out to be a poor investment. We have preserved the ability to participate in good outcomes and insulated ourselves from some bad ones.

Moving on to Advanced Options Trading. Thanks for sharing this information with us……its nice and keep posting. For example, you could purchase a put option to sell your shares of a stock if you are worried that the price might drop suddenly. In case you raise initially of the game you have to be distinct which you have a successful hands. Once you've mastered simple options trading and have decided to move on to more complex options trading, you need to learn about the so-called "Greeks. Not all investors are allowed to trade every kind of strategy, since some strategies involve substantial risk.

For both of these reasons, being able to defer the investment decision is valuable. Traditional NPV misses the extra value associated with deferral because it assumes the decision cannot be put off. In contrast, option pricing presumes the ability to defer and provides a way to quantify the value of deferring. So to value the investment, we need to develop two new metrics that capture these extra sources of value. The first source of value is the interest you can earn on the required capital expenditure by investing later rather than sooner.

How much money is that? It is the discounted present value of the capital expenditure. To compute PV X , we discount X for the requisite number of periods t at the risk-free rate of return r f :.

The extra value is the interest rate r f times X , compounded over however many time periods t are involved. Alternatively, it is the difference between X and PV X. We have seen that NPV can be expressed in option notation as:. Note that our modified NPV will be greater than or equal to regular NPV because it explicitly includes interest to be earned while we wait. It picks up one of the sources of value we are interested in.

Modified NPV can be positive, negative, or zero. However, it will make our calculations a lot easier if we express the relationship between cost and value in such a way that the number can never be negative or zero. By converting the difference to a ratio, all we are doing, essentially, is converting negative values to decimals between zero and one. That possibility is very important, but naturally it is more difficult to quantify because we are not actually sure that asset values will change or, if they do, what the future values will be.

Fortunately, rather than measuring added value directly, we can measure uncertainty instead and let an option-pricing model quantify the value associated with a given amount of uncertainty.

The only way to measure uncertainty is by assessing probabilities. How can we quantify this uncertainty? Perhaps the most obvious measure is simply the range of all possible values: the difference between the lowest and the highest possibilities. But we can do better than that by taking into account the relative likelihood of values between those extremes.

Variance is a summary measure of the likelihood of drawing a value far away from the average value in the urn. The higher the variance, the more likely it is that the values drawn will be either much higher or much lower than average.

In other words, we might say that high-variance assets are riskier than low-variance assets. We have to worry about a time dimension as well: how much things can change while we wait depends on how long we can afford to wait. For business projects, things can change a lot more if we wait two years than if we wait only two months. So in option valuation, we speak in terms of variance per period.

This sometimes is called cumulative variance. An option expiring in two years has twice the cumulative variance as an otherwise identical option expiring in one year, given the same variance per period. Cumulative variance is a good way to measure the uncertainty associated with business investments.

A Brief History of Binary Options

The probability distribution of possible values is usually quite asymmetric; value can increase greatly but cannot drop below zero. Returns, in contrast, can be positive or negative, sometimes symmetrically positive or negative, which makes their probability distribution easier to work with. Second, it helps to express uncertainty in terms of standard deviation rather than variance. Standard deviation is simply the square root of variance and is denoted by o. It tells us just as much about uncertainty as variance does, but it has the advantage of being denominated in the same units as the thing being measured.

In our business example, future asset values are denominated in units of currency—say, dollars—and returns are denominated in percentage points. Standard deviation, then, is likewise denominated in dollars or percentage points, whereas variance is denominated in squared dollars or squared percentage points, which are not intuitive.

Since we are going to work with returns instead of values, our units will be percentage points instead of dollars. Third, take the square root of cumulative variance to change units, expressing the metric as standard deviation rather than variance.

A New Watchlist

They capture the extra sources of value associated with opportunities. And they are composed of the five fundamental option-pricing variables onto which we mapped our business opportunity. NPVq is actually a combination of four of the five variables: S, X, r f , and t. Finally, each of the metrics has a natural business interpretation, which makes option-based analysis less opaque to non-finance executives. Combining five variables into two lets us locate opportunities in two-dimensional space.

NPVq is on the horizontal axis, increasing from left to right. As NPVq rises, so does the value of the call option. What causes higher values of NPVq? Higher project values S or lower capital expenditures X. Note further that NPVq also is higher whenever the present value of X is lower. Higher interest rates r f or longer time to expiration t both lead to lower present values of X.

Any of these changes lower X or higher S, r f , or t increases the value of a European call. Locating the Option Value in Two-Dimensional Space We can locate investment opportunities in this two-dimensional space.

Cumulative volatility is on the vertical axis of the graph, increasing from top to bottom. Plotting projects in this two-dimensional space creates a visual representation of their relative option values. No matter where you start in the graph, call value increases when you move down, to the right, or in both directions at once.
