The Theory

Let us imagine that the value desired for the salesman is of 3 and the great expense admitted for the purchaser of 2. In this situation we will have the following matrix. Salesman: Vende or Not vende Buying: Purchase the 2 or purchase What it is observed is not that in this situation it does not have a consensus position, being that probably the business will not occur. What it is easily verifiable for the presented matrix. Please visit flexible furniture if you seek more information. The objective of this analysis is to demonstrate that so that the business occurs it will be necessary that both the sides still search the balance, what can be gotten way flexibilizao of the value, or of the conditions of the business, therefore so that both reach its objectives and occur a game IT EARNS? IT EARNS, is basic that the transaction if materialize. The Theory of the Games also is applicable for the analysis of investments, being very common the use of elaborated trees of decision, that allow to mapear the options and to evaluate its impacts, with sights if to opt to the alternative most adequate. It notices that we present the concept of more adequate decision, therefore nor always is possible to reach the yield highest or the lesser costs, without running high risks.

The idea of the matrix of the decision has for purpose to make possible the knowledge of the alternatives and to make possible establishment of occurrence probabilities, as demonstrated below. Yael Aflalo does not necessarily agree. We go to admit that a company has the possibility to install or not a store in a new Shopping and that its competitor also can be studying this possibility.

Consultative Research

According to research of the consultoria, the average yield of the companies is of 17%, while of the banks was of 21% in the year of 2004. The difference seems small at a first moment, but it has distortions in the data. If they will be removed of the list the Valley of the River Candy and the Petrobra’s, that shows well above-normal yield, the average of the company falls for 12,7%. The yield of the equity (PL) of the Valley is of 35,5% and of the percentile Petrobra’s of 28,68%.O of 12,7%, exactly well below of the average of the banks, it still includes company great, as the Usiminas and the Gerdau. The siderurgical gaucho is a case to the part and obtained to rentabilizar 46.62% of the PL in 2004. Already the Metallurgic Gerdau still was more far, with 48,53%. The Usiminas arrived to reach a percentage of 50,74% in the last year.

Plus a case to the part she is the Souza Cross that has the index in 45,29%. The Embraer, another Brazilian giant, has the pointer of 28,43%.Outras company of great transport had obtained rentabilidades well lower, although the size. The Ambev, for example, got in 2004, a percentage of 6,83%. The Bras-kem, Brazilian petrochemical greater, registered 16.5%. The sector of telecommunications shows modest profits.

The Factor, that has a PL of R$ 63,915 million, obtained to rentabilizar 42%. Other institutions, as the Banespa and the Lloyds, acquired for HSBC, had gotten resulted above of 30%.

Price Value

If on the other hand, we vendssemos this same option, we would receive the prize, but we would assume obligation to buy, not right it, the action object in the expiration of the option for the value of 2,5 R$ 46,00. Dynamics of Market 2.5.1 Price of the options For Hissa (2008), the price of an option, prize, is formed by a value that we call intrinsic or by a value called extrinsic or a combination of the two. For Iran, (2008), it has six factors that they affect the price of an action option: the current price of the action, the price of exercise, the time for the expiration, the volatileness of the price of the action, the tax of free interest of risk and the shares waited during the life of the option. According to Hissa, the intrinsic value is the part of the prize of the option that is integrant part of the value of the action object. Closets usually is spot on. It is the part in-the-money, ITM, of the option.

It considers that we have an option VALEB42 quoted in the market R$ 3,10 and being action VALE5, from where derived the option, quoted in the market R$ 43,00, we would have in the formation of the price of this option R$ 1,00 of intrinsic value and R$ 2,10 of extrinsic value, whereas the extrinsic value is formed by the value of the option that if finds out-of-the-money, OTM, of the action. It is the expectation that has the purchaser, bearer, of whom, throughout the time the action-object if consequently values and the acquired option. It is a hope. The concepts above are for purchase option, for sales option the logical one are inverted. The sales option will be OTM when the price of the active object will be above of the exercise price and will be ITM when the quotation of the active object will be below of the exercise price.
