Explain why it has proved impossible to derive an analytical formula for valuing
American Puts, and outline the main techniques that are used to produce approximate valuations for such securities
Investing in stock options is a way used by investors to hedge against risk. It is simply because all the investors could lose if the option is not exercised before the expiration rate is just the option price (that is the premium) that he or she has paid earlier. Call options give the investor the right to buy the underlying stock at the exercise price, X; while the put options give the investor the right to sell the underlying security at X. However only America options can be exercised at any time during the life of the option if the holder sees fit while European options can only be exercised at the expiration rate, and this is the reason why American put options are normally valued higher than
European options. Nonetheless it has been proved by academics that it is impossible to derive an analytical formula for valuing American put options and the reason why will be discussed in this paper as well as some main suggested techniques that are used to value them.
According to Hull, exercising an American put option on a non-dividend-paying stock early if it is sufficiently deeply in the money can be an optimal practice.
For example, suppose that the strike price of an American option is $20 and the stock price is virtually zero. By exercising early at this point of time, an investor makes an immediate gain of $20. On the contrary, if the investor waits, he might not be able to get as much as $20 gain since negative stock prices are impossible. Therefore it implies that if the share price was zero, the put would have reached its highest possible value so the investor should exercise the option early at this point of time.
Additionally, in general, the early exerices of a put option becomes more attractive as S, the stock price, decreases; as r, the risk-free interest rate, increases; and as , the volatility, decreases. Since the value of a put is always positive as the worst can happen to it is that it expires worthless so this can be expressed as where X is the strike price Therefore for an American put with price P, , must always hold since the investor can execute immediate exercise any time prior to the expiry date. As shown in Figure 1,
Refer to OMS case, if the modification to the terms of the award was made on January 1, 2017, this implies that the modified share options are immediately vested. Therefore, the additional compensation cost should be recognized in the 2017.

“Batter up!” the umpire yelled from behind home plate on the diamond-shaped field for the inning to begin. Adrenaline rushed through the players’ veins as the crowd cheering echoed from the bleachers to the outfield. Softball and baseball are team sports which both require an umpire and a diamond shaped field. All players are important. Most aspects of the games are the same. Each team has only nine players on the field at nine different positions. Each inning ends when there are three outs. Baseball generally consists of nine innings, whereas softball usually is played in seven innings. People think that softball is not as tough as baseball because they think that softball is a soft sport. I have been playing softball for about ten years, but prior to that I played baseball. However, the game of softball is on a whole different level. Softball plays require much more speed, and there is a greater possibility of getting injured. The game of softball is more hazardous and fast-paced than baseball.
After evalutating both the Black-Scholes Model and the Brownian Motion, we have come to know that the Black-Scholes Model is quite predictive as it gets close to the observed price. We found that with the Brownian motion it may take on negative values which results certain modelling prices to be frowned upon , hence making Black-Scholes Model more realistic. As we ventured in this study, we found that there is still more research to be done since many of the modern option models stems from the Black-Scholes model. Thus making the modern option pricing models more
In the short story “Everyday Use” by Alice Walker, a relationship between a mother and daughter is destroyed due to conflicting views and insecurities. This story exemplifies the painful but honest truth in what can happen in families today. As children grow up and go off into the world, they cross paths with new people and become caught up in the never-ending whirlwind of differing opinions and a new identity within themselves. Many grow into the false realization that they have to come in touch with their culture, without first understanding where they are truly from. This story essentially comes down to a lack of connection between loved ones and their families.
The phrase: "the world is flat" can be interpreted in many ways. Basically what Friedman means by "flat" is "linked." The falling of trade and political barriers and technical advances have made it possible to do business, instantaneously with billions of other people around the world. It has allowed for parts of the world, which had previously been cut off, like China and India, to successfully compete in the world market. Thus, the playing field is being leveled, and no one nation has an advantage. Friedman could also refer to a "flat world" in a metaphorical sense. In a spherical earth you cannot see around the world and cannot recognize the opportunities far from where you live. If the world were flat you could see it all. There would be no barriers to get in your way. This is the equivalent to a smaller globe which allows one to reach far away opportunities.
It is very hard not to realize that technology has overpowered education in many ways. “Technology integration is similar to a tidal wave, growing silently in strength, then falling with an unstoppable roar upon those who paid no attention or showed little interest” (Guhlin, 40). Nowadays, computers are almost considered a necessity in the classroom, and are the main component of technology integration. Computers are being used in more numerous ways, besides only being used for basic word processing. With a simple computer, copious availabilities of technologies can be used in the classroom. “The one thing that is so great about the computer is that it does give a lot of instruction--and you don't need to have hearing to take advantage of it” (Anderson, 12). It’s amazing how one simple screen can provide everlasting opportunity for learning.
In your response, build upon extant portfolio theory and make sure to talk about different types of risks that investors might face and how they go about managing such risks. This means you need to consider topics such as efficient frontier and optimal portfolios; as well their relevance to investment theory. Furthermore, given the nature of the assignment, avoid bringing the brokerage industry into your discussion. In other words, assume you can invest directly in the stock market and do not need any financial intermediaries like brokerage houses.

In college, attendance is crucial to students’ success. Being late to class can result in having less time to take a test or missing fundamental concepts that may be discussed in a classroom. Students must take responsibility by arriving on time; however, limited parking spaces and other transportation problems at many universities can cause students to be late which can result in poor academic performance. The University of Texas at San Antonio, one of most populous cities in Texas, has 29,000 enrolled students (UTSA . . .). During peak hours, one must be timely to find a parking space; many students find themselves driving in circles while hoping to find someone else leaving the campus and others wait for a shuttle bus that has a reputation of arriving late. Due to transportation problems, some students may feel unmotivated to study in the library or go to class regularly. Therefore, the University of Texas at San Antonio should improve student transportation because doing so could increase students’ academic performance.
There are two basic ways of financing for a business: Debt financing and equity financing. Debt financing is defined as 'borrowing money that is to be repaid over a period of time, usually with interest" (Financing Basics, 1). The lender does not gain any ownership in the business that is borrowing. Equity financing is described as "an exchange of money for a share of business ownership" (Financing Basics, 1). This form of financing allows the business to obtain funds without having to repay a specific amount of money at any particular time. There are also a few different instruments that could be defined as either debt or equity. One such instrument is stock options that an employee can exercise after so many years with the company. Either using the debt or equity method, or a combination of the two methods can be used to account for stock options or other instruments with the similar characteristics.
If you are able to hold onto your bond until the maturity date is reached, temporary changes in
It is hard to find parking on campus, especially during rush hours. Both students and professors are encountering trouble for this crisis. As a simple example, the parking lot next to the Sarkeys building is always full. This problem is a continuous, daily hazard. As a student required to maintain a lot of class schedules and activities, I suffer from the parking problem daily and find that others encounter the same. It is true that the university is working on a new parking garage, but during the construction process, there is no alternative way to settle the crisis. The official home page of OU parking and transportation services is a source to consider for exploring the problem.
