How To Calculate Stock Quotes

Consider brokerage and taxes while calculating profit and loss:-

If you can distill the essence of GE's stock behavior over the past twenty years, then you can apply it to financial engineering. You can estimate the risk of holding the stock over the next twenty years. You can estimate how many shares of the stock to buy for your portfolio. You can calculate the proper value of options you want to trade on the stock.

While some methods of calculation find that cancer and its patients take up too many resources, from another angle, cancer patients are cash cows. Each cancer patient generates millions of dollars in revenues. If one wonders why we would extend the life of a pancreatic patient for a dozen days with a $16,000 drug, let’s remember that this money does not evaporate after twelve days; it continues to circulate in stock prices, salaries, and smaller crumbs of an infinitely profitable cancer pie. Just as the demon of communism justified the proliferation of a lucrative nuclear industry, so cancer fills the core of so many economies that if a cure were to be found, the economy might just crash.

A 1997 study of the consumer product design firm IDEO found that most of the company’s biggest successes originated as “combinations of existing knowledge from disparate industries.” IDEO’s designers created a top-selling water bottle, for example, by mixing a standard water carafe with the leak-proof nozzle of a shampoo container. The power of combining old ideas in new ways also extends to finance, where the prices of stock derivatives are calculated by mixing formulas originally developed to describe the motion of dust particles with gambling techniques. Modern bike helmets exist because a designer wondered if he could take a boat’s hull, which can withstand nearly any collision, and design it in the shape of a hat. It even reaches to parenting, where one of the most popular baby books—Benjamin Spock’s The Common Sense Book of Baby and Child Care, first published in 1946—combined Freudian psychotherapy with traditional child-rearing techniques. “A lot of the people we think of as exceptionally creative are essentially intellectual middlemen,” said Uzzi. “They’ve learned how to transfer knowledge between different industries or groups. They’ve seen a lot of different people attack the same problems in different settings, and so they know which kinds of ideas are more likely to work.” Within sociology, these middlemen are often referred to as idea or innovation brokers. In one study published in 2004, a sociologist named Ronald Burt studied 673 managers at a large electronics company and found that ideas that were most consistently ranked as “creative” came from people who were particularly talented at taking concepts from one division of the company and explaining them to employees in other departments. “People connected across groups are more familiar with alternative ways of thinking and behaving,” Burt wrote. “The between-group brokers are more likely to express ideas, less likely to have ideas dismissed, and more likely to have ideas evaluated as valuable.” They were more credible when they made suggestions, Burt said, because they could say which ideas had already succeeded somewhere else.

To oversee all the details yourself in person; to be at once pilot and captain, and owner and underwriter; to buy and sell and keep the accounts; to read every letter received, and write or read every letter sent; to superintend the discharge of imports night and day; to be upon many parts of the coast almost at the same time—often the richest freight will be discharged upon a Jersey shore;—to be your own telegraph, unweariedly sweeping the horizon, speaking all passing vessels bound coastwise; to keep up a steady despatch of commodities, for the supply of such a distant and exorbitant market; to keep yourself informed of the state of the markets, prospects of war and peace everywhere, and anticipate the tendencies of trade and civilization—taking advantage of the results of all exploring expeditions, using new passages and all improvements in navigation;—charts to be studied, the position of reefs and new lights and buoys to be ascertained, and ever, and ever, the logarithmic tables to be corrected, for by the error of some calculator the vessel often splits upon a rock that should have reached a friendly pier—there is the untold fate of La Prouse;—universal science to be kept pace with, studying the lives of all great discoverers and navigators, great adventurers and merchants, from Hanno and the Phoenicians down to our day; in fine, account of stock to be taken from time to time, to know how you stand.

some small counting house on the coast, in some Salem harbor, will be fixture enough. You will export such articles as the country affords, purely native products, much ice and pine timber and a little granite, always in native bottoms. These will be good ventures. To oversee all the details yourself in person; to be at once pilot and captain, and owner and underwriter; to buy and sell and keep the accounts; to read every letter received, and write or read every letter sent; to superintend the discharge of imports night and day; to be upon many parts of the coast almost at the same time—often the richest freight will be discharged upon a Jersey shore;—to be your own telegraph, unweariedly sweeping the horizon, speaking all passing vessels bound coastwise; to keep up a steady despatch of commodities, for the supply of such a distant and exorbitant market; to keep yourself informed of the state of the markets, prospects of war and peace everywhere, and anticipate the tendencies of trade and civilization—taking advantage of the results of all exploring expeditions, using new passages and all improvements in navigation;—charts to be studied, the position of reefs and new lights and buoys to be ascertained, and ever, and ever, the logarithmic tables to be corrected, for by the error of some calculator the vessel often splits upon a rock that should have reached a friendly pier—there is the untold fate of La Prouse;—universal science to be kept pace with, studying the lives of all great discoverers and navigators, great adventurers and merchants, from Hanno and the Phoenicians down to our day; in fine, account of stock to be taken from time to time, to know how you stand. It is a labor to task the faculties of a man—such problems of profit and loss, of interest, of tare and tret, and gauging of all kinds in it, as demand a universal knowledge. I have thought that Walden Pond would be a good place for business, not solely on account of the railroad and the ice trade; it offers advantages which it may not be good policy to divulge; it is a good port and a good foundation. No Neva marshes to be filled; though you must everywhere build on piles of your own driving. It is said that a flood-tide, with a westerly wind, and ice in the Neva, would sweep St. Petersburg from the face of the earth. As this business was to be entered into without the usual capital, it may not be easy to conjecture where those means, that will still be indispensable to every such undertaking, were to be obtained.

By now, though, it had been a steep learning curve, he was fairly well versed on the basics of how clearing worked: When a customer bought shares in a stock on Robinhood — say, GameStop — at a specific price, the order was first sent to Robinhood's in-house clearing brokerage, who in turn bundled the trade to a market maker for execution. The trade was then brought to a clearinghouse, who oversaw the trade all the way to the settlement. During this time period, the trade itself needed to be 'insured' against anything that might go wrong, such as some sort of systemic collapse or a default by either party — although in reality, in regulated markets, this seemed extremely unlikely. While the customer's money was temporarily put aside, essentially in an untouchable safe, for the two days it took for the clearing agency to verify that both parties were able to provide what they had agreed upon — the brokerage house, Robinhood — had to insure the deal with a deposit; money of its own, separate from the money that the customer had provided, that could be used to guarantee the value of the trade. In financial parlance, this 'collateral' was known as VAR — or value at risk. For a single trade of a simple asset, it would have been relatively easy to know how much the brokerage would need to deposit to insure the situation; the risk of something going wrong would be small, and the total value would be simple to calculate. If GME was trading at $400 a share and a customer wanted ten shares, there was $4000 at risk, plus or minus some nominal amount due to minute vagaries in market fluctuations during the two-day period before settlement. In such a simple situation, Robinhood might be asked to put up $4000 and change — in addition to the $4000 of the customer's buy order, which remained locked in the safe. The deposit requirement calculation grew more complicated as layers were added onto the trading situation. A single trade had low inherent risk; multiplied to millions of trades, the risk profile began to change. The more volatile the stock — in price and/or volume — the riskier a buy or sell became. Of course, the NSCC did not make these calculations by hand; they used sophisticated algorithms to digest the numerous inputs coming in from the trade — type of equity, volume, current volatility, where it fit into a brokerage's portfolio as a whole — and spit out a 'recommendation' of what sort of deposit would protect the trade. And this process was entirely automated; the brokerage house would continually run its trading activity through the federal clearing system and would receive its updated deposit requirements as often as every fifteen minutes while the market was open. Premarket during a trading week, that number would come in at 5:11 a.m. East Coast time, usually right as Jim, in Orlando, was finishing his morning coffee. Robinhood would then have until 10:00 a.m. to satisfy the deposit requirement for the upcoming day of trading — or risk being in default, which could lead to an immediate shutdown of all operations. Usually, the deposit requirement was tied closely to the actual dollars being 'spent' on the trades; a near equal number of buys and sells in a brokerage house's trading profile lowered its overall risk, and though volatility was common, especially in the past half-decade, even a two-day settlement period came with an acceptable level of confidence that nobody would fail to deliver on their trades.

Not only did this gain Sharpe his PhD, but it eventually evolved into a seminal paper on what he called the “capital asset pricing model” (CAPM), a formula that investors could use to calculate the value of financial securities. The broader, groundbreaking implication of CAPM was introducing the concept of risk-adjusted returns—one had to measure the performance of a stock or a fund manager versus the volatility of its returns—and indicated that the best overall investment for most investors is the entire market, as it reflects the optimal tradeoff between risks and returns.

Reconstructing family life amid the chaos of the cotton revolution was no easy matter. Under the best of circumstances, the slave family on the frontier was extraordinarily unstable because the frontier plantation was extraordinarily unstable. For every aspiring master who climbed into the planter class, dozens failed because of undercapitalization, unproductive land, insect infestation, bad weather, or sheer incompetence. Others, discouraged by low prices and disdainful of the primitive conditions, simply gave up and returned home. Those who succeeded often did so only after they had failed numerous times. Each failure or near-failure caused slaves to be sold, shattering families and scattering husbands and wives, parents and children. Success, moreover, was no guarantee of security for slaves. Disease and violence struck down some of the most successful planters. Not even longevity assured stability, as many successful planters looked west for still greater challenges. Whatever the source, the chronic volatility of the plantation took its toll on the domestic life of slaves. Despite these difficulties, the family became the center of slave life in the interior, as it was on the seaboard. From the slaves' perspective, the most important role they played was not that of field hand or mechanic but husband or wife, son or daughter - the precise opposite of their owners' calculation. As in Virginia and the Carolinas, the family became the locus of socialization, education, governance, and vocational training. Slave families guided courting patterns, marriage rituals, child-rearing practices, and the division of domestic labor in Alabama, Mississippi, and beyond. Sally Anne Chambers, who grew up in Louisiana, recalled how slaves turned to the business of family on Saturdays and Sundays. 'De women do dey own washing den. De menfolks tend to de gardens round dey own house. Dey raise some cotton and sell it to massa and git li'l money dat way.' As Sally Anne Chambers's memories reveal, the reconstructed slave family was more than a source of affection. It was a demanding institution that defined responsibilities and enforced obligations, even as it provided a source of succor. Parents taught their children that a careless word in the presence of the master or mistress could spell disaster. Children and the elderly, not yet or no longer laboring in the masters' fields, often worked in the slaves' gardens and grounds, as did new arrivals who might be placed in the household of an established family. Charles Ball, sold south from Maryland, was accepted into his new family but only when he agreed to contribute all of his overwork 'earnings into the family stock.' The 'family stock' reveals how the slaves' economy undergirded the slave family in the southern interior, just as it had on the seaboard. As slaves gained access to gardens and grounds, overwork, or the sale of handicraft, they began trading independently and accumulating property. The material linkages of sellers and buyers - the bartering of goods and labor among themselves - began to knit slaves together into working groups that were often based on familial connections. Before long, systems of ownership and inheritance emerged, joining men and women together on a foundation of need as well as affection.

To simplify Markowitz’s model, Sharpe stipulated one fundamental underlying factor—the return of the overall stock market—and instead calculated the variation of individual securities relative to this, rather than each security relative to each other. In his formula, it was given the Greek letter beta. So if Coca-Cola’s shares rise by 0.8 percentage points for every 1 percent the broader stock market climbs, it has a beta of 0.8. If a racier stock gains 2 percent, it has a beta of 2. Higher-beta stocks are more volatile, and should therefore offer greater returns than steadier, lower-beta securities. And thus beta became the lingua franca for the returns of the stock market as a whole, while “alpha” later emerged as the term for the extra returns generated by a skilled investor.

Delta, a function of interest rates, is a measure of exactly how much stock a futures contract hedges. It was an easy calculation. I

Everybody wished to confess, not to admit anything. The sins they remembered, before the end of the world, were general rather than particular. Nobody even knew how to tell the time. Banks of computers around the planet were predicted to crash when the end of the millennium arrived. All the machinery dependent on electronic calculation would go: jumbo jets and atomic power plants, satellites and radio stations, nuclear submarines beneath the ice caps and the stock exchange in New York. Each sin demanded to be told to its full extent before the day arrived. The culprits counted them out one after the other, arriving at a total just as if they were finding the sums of the cents in their hands. But there was no simple way to measure sin.

Explaining their allure, Milken said, “The opportunity to be true to yourself in high-yield bonds is great. It is not like buying a stock. With a stock, its value is generally dependent upon investors’ collective perceptions of the future. No matter how much research you have done regarding a particular stock, you don’t have a contract as to what the future price will be. But with a high-yield bond there is a date certain in the future when it matures, and if you hold it to maturity and your analysis is correct, you will be correct in your calculation of your yield—and you do have a contract as to future price. One is certain if you’re right. The other is not.

Hence, after this foreshortened discussion of the major considerations, we once again enunciate the same basic compromise policy for defensive investors—namely that at all times they have a significant part of their funds in bond-type holdings and a significant part also in equities. It is still true that they may choose between maintaining a simple 50–50 division between the two components or a ratio, dependent on their judgment, varying between a minimum of 25% and a maximum of 75% of either. We shall give our more detailed view of these alternative policies in a later chapter. Since at present the overall return envisaged from common stocks is nearly the same as that from bonds, the presently expectable return (including growth of stock values) for the investor would change little regardless of how he divides his fund between the two components. As calculated above, the aggregate return from both parts should be about 7.8% before taxes or 5.5% on a tax-free (or estimated tax-paid) basis. A return of this order is appreciably higher than that realized by the typical conservative investor over most of the long-term past. It may not seem attractive in relation to the 14%, or so, return shown by common stocks during the 20 years of the predominantly bull market after 1949. But it should be remembered that between 1949 and 1969 the price of the DJIA had advanced more than fivefold while its earnings and dividends had about doubled. Hence the greater part of the impressive market record for that period was based on a change in investors’ and speculators’ attitudes rather than in underlying corporate values. To that extent it might well be called a “bootstrap operation.” In

Here’s how to calculate the dividend yield of a stock: Take the annual dividend payment ($1.56 in this case) and divide it by the current price of the stock ($41.55). In this case, that gives you 0.03754513, or 3.75%. 3.75% is Coke’s current dividend yield.

The Dark Cloud Is the memory bank you have which time does not seem to heal Is the speed with which you block men who lie that they care about how you feel Is the questioning of where society is going and whether our icy coldness will lead us to complete destruction Is the stock market obsession some of us have and how we crave calculated instruction

Come on, I mean it, tell me, how does it work?' said Maxentius-Drontio. 'I am interested, and not just because I am bored.' 'Hmm, calculating potential for targeted, induced social embarrassment.' The magos stopped, stock-still. Something clicked in his chest. 'Risks acceptable. Bond with me. Pass me that size nine molecular manipulator, please, in order to initiate emotional pairing,' said Fe.

Kuznets himself, however, would not have chosen this as the picture of economic progress because he was well aware of the limits of his ingenious calculations from the outset. Emphasising that national income captured only the market value of goods and services produced in an economy, he pointed out that it therefore excluded the enormous value of goods and services produced by and for households, and by society in the course of daily life. In addition, he recognised that it gave no indication of how income and consumption were actually distributed between households. And since national income is a flow measure (recording only the amount of income generated each year), Kuznets saw that it needed to be complemented by a stock measure, accounting for the wealth from which it was generated, and its distribution. Indeed, as GNP reached the height of its popularity in the early 1960s, Kuznets became one of its most outspoken critics, having warned from the start that ‘the welfare of a nation can scarcely be inferred from a measure of national income’.
