Investors Valuation of Stock Essay Example for Free

Investors Valuation of Stock Essay An investor should value a stock by looking at the intrinsic value of the stock and how the market value compare to the intrinsic value. The most common mathematical method of valuing stock is to determine the price earnings ratio (P/E). The P/E ratio is calculated by dividing the share price by the company’s net income. As a general rule a P/E ratio should be in the higher teens. Stocks with a below-market P/E are considered cheaper, and a higher P/E ratio are considered expensive (Kansas, 2014). To evaluate if a stock is under or over-valued investors should look at the CAPM (Market securities Line) based on the Beta of the company and determine the performance of the stock. An investor can use indexes, such as the Dow Jones, NYSE, or SP 500, in stock valuation. Value investing is common for investors. It is misrepresentation of price so the buyer buys a stock at a lower price than true worth or sells at a higher price than true worth. Considering all variables and determining true fault in price, this method provides investors easy margins. Investors’ value stocks using various strategies and methods, but all driving factors are in hopes of gaining margin and growth of the company invested in. The concept of stock valuation is simple. However, predicting the future is not as simple and can be complicated. Market Valuation of Stock Market and investors value stock differently. The market depends on expectations and recent information available to the market. The market’s value of stock are usually based on past history and trends. Based on current economic conditions we look at the past and see how it would look going forward. Through use of charts, value lines, or other indicators, the market looks at certain things such as floors, ceiling, resistance points, when valuing stock. The stock value is a collective price based on numerous variables considered, equaling a company’s worth combined with social trends and economic factors. The most common value of a stock for the market is the open and close prices. NASDAQ uses an auction approach called opening cross and closing cross to determine stock prices (â€Å"Stock Market Prices†, 2014). The opening cross uses computer software to determine opening prices for stocks based on night trading; buying and selling of stock during close of business. The closing cross software calculates closing price based on  that day’s trades. The technology takes into consideration each trade made at the exchange and sets what is referred to as the fairest closing price. The final stock prices are released after close of the exchange and work as a main factor for night trading. The amount an investor is willing to pay is often dependent on the prices set by the market. Stock Market Prices. (2014). http://money.howstuffworks.com/nasdaq-opening-closing- cross1.htm Kansas, D.

Sickle Cell Anemia :: Health, Medicine, Cells

Sickle cell anemia primarily affects people with African, Mediterranean, Middle Eastern, and Indian ancestry (Learn genetics, 2010; NHLBI, n.d.; Vorvick et al., 2010). Sickle cell anemia occurs when a person inherits two sickle cell gene, one from each parent, that cause the red blood cells to change and become crescent shaped. The underlying problem involves hemoglobin, a component of the red blood cells. Hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs (Nabili, 2008, para. 1). In sickle cell anemia, the hemoglobin is flawed. As a result, the cells become sickle shaped and can’t travel as easily through blood vessels. Sickle cell anemia is an illness which has one primary cause, but a variety of symptoms and treatments. Like most illnesses, sickle cell anemia has one primary cause. In order for sickle cell anemia to occur, a sickle cell gene must be inherited from both the mother and the father, so that the child has two sickle cell genes (Shiel, 2006, para. 3). The sickle cell gene causes the body to make abnormal hemoglobin. As mentioned above, hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs (Nabili, 2008, para. 1). A person with normal red blood cell will have hemoglobin A, however a person with sickle cell disease will have hemoglobin S (Sickle cell Disease Association of America, Inc.,2005, para 3). Normal red blood cells are usually round and soft and travel easily through small vessels; however sickle cells are abnormally shaped and stiff, thus causing them to have difficulty travelling through small vessels. Sickle cells can clog vessels depriving tissues of oxygen. A s spoken of in two articles, sickle cells have a shorter life span than normal red blood cells. Normal red blood cells can live 120 days compared to sickle cells that only last 10 to 20 days, resulting in anemia. (Learn genetics, 2010 & Nabili, 2008) Sickle cell anemia does not only have one primary cause, but also has a variety of symptoms. Sickle cell anemia has various symptoms that may vary upon every individual. All the symptoms that a person may experience are basically the direct result of the abnormal shaped blood cells. These cells deprive tissues of oxygen and in time the lack of oxygen to the tissues damages the organs and leads to pain.

Ketone Reduction Using Sodium Borohydride

Experiment 5B: Ketone Reduction Objective: Using sodium borohydride as a reducing agent, the ketone 4-tert-butylcyclohexane is reduced to its corresponding alcohol. It is purified through extraction techniques to give the cis and trans diasteromer products. Procedure: The procedure was followed as outlined in Mayo’s book for Experiment 5B with the following modifications: 1. Reagents and Equipment – The reaction will be on a scale of 2X what is described in the text. 2. Reagents and Equipment – The progress of the reaction will be followed by TLC as directed in the Reaction Conditions section.Glass backed TLC plates will be created with the following three spots: Ketone Standard/Co-Spot/Crude Reaction Mixture. Prepare the TLC plate while the reaction is being set up. To the initial solution of 4-tert-butylcyclohexane in methanol, before adding the reducing solution, insert a TLC capillary. Use this sample as your ketone standard. Do NOT stop the reaction before c hecking the progress by TLC. If the reaction is not complete, add another portion of the reducing solution. 3. Isolation of Product – All other amounts specified in this section should be followed without doubling. . Isolation of Product – Substitute 1. 0 mL of cold 3. 0 M HCl for 1. 0 mL of cold 0. 1 M HCl. 5. Purification and Characterization – Will not obtain an NMR spectrum.

Christmas Weather Lore

Weather lore exists for nearly every season and every type of weather, but many of the most well-known sayings have to do with winter weather.   Besides hoping for a White Christmas, theres another reason youll want to keep a watchful eye on your Christmas Day forecast. According to weather folklore, the weather on Christmas foretells the weather for the remaining winter and upcoming year.   Based on the below sayings, what does your Christmas Day weather suggest? Stormy Christmas Weather   - If theres thunder during Christmas week,The Winter will be anything but meek. - If windy on Christmas, trees will bring much fruit. - If it rain much during the twelve days after Christmas Day it will be a wet year. A Mild Christmas Means Cold Will Come   - A green (warm) Christmas, a white (cold) Easter. - So far as the sun shines on Christmas Day,So far will the snow blow in May. - If the ice will bear a goose before Christmas, it will not bear a duck after. - If Christmas day be bright and clear, therell be two winters in the year.. The below proverbs could be used to forecast whether or not youll see a White Christmas based on the weather at Hollantide -- a Cornish feast traditionally celebrated at the end of October/first of November  which marked the eve of winter. - If ducks do slide at Hollantide,At Christmas they will swim.If ducks do swim at Hollantide,At Christmas they will slide. - If Candlemas day be dry and fair,The half of the winter is gone and mair.If Candlemas day be wet and foul,The half of the winter is gone at Yule (Christmas). The following sayings have less to do with the weather on Christmas and more to do with what calendar day Christmas falls on:   - If Christmas Day on Thursday be,A windy winter ye shall see. - It will be the same weather for nine weeks as it is on the ninth day after Christmas. - The nearer the New Moon to Christmas Day, the harder the Winter. Christmas Lore: Where Does It Come From?   Why are these particular Christmas weather scenarios linked to these weather occurrences? Long before there was such a thing as  meteorologists  or tools like barometers or thermometers, farmers, seafarers, and others whose daily work was tied to the weather had nothing to clue them in on what the days weather would bring. To remedy this, people began observing how animals, plants, insects, and even they themselves behaved just before certain weather events. After years and years of noticing these patterns, folks began expecting certain weather based on whether or not they observed these certain events in nature.  They then created rhymes (like those above) to make the connections easily remembered and shared. How many of the above pieces of lore have you heard before? Have you known any of them to ring true where you live?
