In finance, stock (also capital stock) consists of all the

"stock - ''especially AmE'' one of the shares into which ownership of a company is divided, or these shares considered together"
"When a company issues shares or stocks ''especially AmE'', it makes them available for people to buy for the first time." (Especially in American English, the word "stocks" is also used to refer to shares.)

), or voting power, often dividing these up in proportion to the amount of money each stockholder has invested. Not all stock is necessarily equal, as certain classes of stock may be issued for example without voting rights, with enhanced voting rights, or with a certain priority to receive profits or liquidation proceeds before or after other classes of shareholders.
Stock can be bought and sold privately or on stock exchanges, and such transactions are typically heavily regulated by governments to prevent fraud, protect investors, and benefit the larger economy. The stocks are deposited with the depositories in the electronic format also known as Demat account. As new shares are issued by a company, the ownership and rights of existing shareholders are diluted in return for cash to sustain or grow the business. Companies can also buy back stock, which often lets investors recoup the initial investment plus capital gains

from subsequent rises in stock price. Stock options issued by many companies as part of employee compensation do not represent ownership, but represent the right to buy ownership at a future time at a specified price. This would represent a windfall to the employees if the option is exercised when the market price is higher than the promised price, since if they immediately sold the stock they would keep the difference (minus taxes).
Shares
A person who owns a percentage of the stock has the ownership of the corporation proportional to their share. The shares form a stock. The stock of a corporation is partitioned into shares, the total of which are stated at the time of business formation. Additional shares may subsequently be authorized by the existing shareholders and issued by the company. In some jurisdictions, each share of stock has a certain declared par value, which is a nominal accounting value used to represent the equity on the balance sheet of the corporation. In other jurisdictions, however, shares of stock may be issued without associated par value.

Types
Stock typically takes the form of shares of either common stock or preferred stock. As a unit of ownership, common stock typically carries voting rights that can be exercised in corporate decisions. Preferred stock differs from common stock in that it typically does not carry voting rights but is legally entitled to receive a certain level of dividend
A dividend is a distribution of profits by a corporation to its shareholders. When a corporation earns a profit or surplus, it is able to pay a portion of the profit as a dividend to shareholders. Any amount not distributed is taken to be re-inv ...

for the holder to convert the preferred shares into a fixed number of common shares, usually any time after a predetermined date. Shares of such stock are called "convertible preferred shares" (or "convertible preference shares" in the UK).
New equity issue may have specific legal clauses attached that differentiate them from previous issues of the issuer. Some shares of common stock may be issued without the typical voting rights, for instance, or some shares may have special rights unique to them and issued only to certain parties. Often, new issues that have not been registered with a securities governing body may be restricted from resale for certain periods of time.
Preferred stock may be hybrid by having the qualities of bonds of fixed returns and common stock voting rights. They also have preference in the payment of dividends over common stock and also have been given preference at the time of liquidation over common stock. They have other features of accumulation in dividend. In addition, preferred stock usually comes with a letter designation at the end of the security; for example, Berkshire-Hathaway Class "B" shares sell under stock ticker BRK.B, whereas Class "A" shares of ORION DHC, Inc will sell under ticker OODHA until the company drops the "A" creating ticker OODH for its "Common" shares only designation. This extra letter does not mean that any exclusive rights exist for the shareholders but it does let investors know that the shares are considered for such, however, these rights or privileges may change based on the decisions made by the underlying company.

Stock" is an American term given to shares of stock subject to SEC Rule 144: Selling Restricted and Control Securities. Under Rule 144, restricted and controlled securities are acquired in unregistered form. Investors either purchase or take ownership of these securities through private sales (or other means such as via ESOPs or in exchange for seed money) from the issuing company (as in the case with Restricted Securities) or from an affiliate of the issuer (as in the case with Control Securities). Investors wishing to sell these securities are subject to different rules than those selling traditional common or preferred stock. These individuals will only be allowed to liquidate their securities after meeting the specific conditions set forth by SEC Rule 144. Rule 144 allows public re-sale of restricted securities if a number of different conditions are met.

are the main types of derivatives on stocks. The underlying security may be a stock index or an individual firm's stock, e.g. single-stock futures.
Stock futures are contracts where the buyer is long, i.e., takes on the obligation to buy on the contract maturity date, and the seller is short, i.e., takes on the obligation to sell. Stock index futures are generally delivered by cash settlement.
A stock option is a class of option. Specifically, a call option is the right (''not'' obligation) to buy stock in the future at a fixed price and a put option is the right (''not'' obligation) to sell stock in the future at a fixed price.

, the state contracted (leased) out many of its services to private companies. These government contractors were called ''publicani'', or ''societas publicanorum'' as individual companies. These companies were similar to modern corporations, or joint-stock companies more specifically, in a couple of aspects. They issued shares called ''partes'' (for large cooperatives) and ''particulae'' which were small shares that acted like today's over-the-counter shares. Polybius mentions that "almost every citizen" participated in the government leases. There is also evidence that the price of stocks fluctuated. The Roman orator Cicero speaks of ''partes illo tempore carissimae'', which means "shares that had a very high price at that time". This implies a fluctuation of price and stock market behavior in Rome.

The Dutch stock market of the 17th century included the use of stock futures, stock options, short selling, the use of credit to purchase shares, a speculative bubble that crashed in 1695, and a change in fashion (namely, in headdresses) that unfolded and reverted in time with the market. Edward Stringham also noted that the uses of practices such as short selling continued to occur during this time despite the government passing laws against it. This is unusual because it shows individual parties fulfilling contracts that were not legally enforceable and where the parties involved could incur a loss. Stringham argues that this shows that contracts can be created and enforced without state sanction or, in this case, in spite of laws to the contrary.
Shareholder
A shareholder (or ''stockholder'') is an individual or company (including a corporation

) that legally owns one or more shares of stock in a joint stock company. Both private and public traded companies have shareholders.
Shareholders are granted special privileges depending on the class of stock, including the right to vote on matters such as elections to the board of directors, the right to share in distributions of the company's income, the right to purchase new shares issued by the company, and the right to a company's assets during a liquidation of the company. However, shareholder's rights to a company's assets are subordinate to the rights of the company's creditors.

Application
The owners of a private company may want additional capital to invest in new projects within the company. They may also simply wish to reduce their holding, freeing up capital for their own private use. They can achieve these goals by selling shares in the company to the general public, through a sale on a stock exchange. This process is called an initial public offering

and even litigation.
In the common case of a publicly traded corporation, where there may be thousands of shareholders, it is impractical to have all of them making the daily decisions required to run a company. Thus, the shareholders will use their shares as votes in the election of members of the board of directors of the company.
In a typical case, each share constitutes one vote. Corporations may, however, issue different classes of shares, which may have different voting rights. Owning the majority of the shares allows other shareholders to be out-voted – effective control rests with the majority shareholder (or shareholders acting in concert). In this way the original owners of the company often still have control of the company.
Shareholder rights
Although ownership of 50% of shares does result in 50% ownership of a company, it does not give the shareholder the right to use a company's building, equipment, materials, or other property. This is because the company is considered a legal person, thus it owns all its assets itself. This is important in areas such as insurance, which must be in the name of the company and not the main shareholder.
In most countries, boards of directors and company managers have a fiduciary responsibility to run the company in the interests of its stockholders. Nonetheless, as Martin Whitman writes:
:...it can safely be stated that there does not exist any publicly traded company where management works exclusively in the best interests of OPMI utside Passive Minority Investorstockholders. Instead, there are both "communities of interest" and "conflicts of interest" between stockholders (principal) and management (agent). This conflict is referred to as the principal–agent problem. It would be naive to think that any management would forego management compensation, and management entrenchment, just because some of these management privileges might be perceived as giving rise to a conflict of interest with OPMIs.
Even though the board of directors runs the company, the shareholder has some impact on the company's policy, as the shareholders elect the board of directors. Each shareholder typically has a percentage of votes equal to the percentage of shares he or she owns. So as long as the shareholders agree that the management (agent) are performing poorly they can select a new board of directors which can then hire a new management team. In practice, however, genuinely contested board elections are rare. Board candidates are usually nominated by insiders or by the board of the directors themselves, and a considerable amount of stock is held or voted by insiders.
Owning shares does not mean responsibility for liabilities. If a company goes broke and has to default on loans, the shareholders are not liable in any way. However, all money obtained by converting assets into cash will be used to repay loans and other debts first, so that shareholders cannot receive any money unless and until creditors have been paid (often the shareholders end up with nothing).

Financing a company through the sale of stock in a company is known as equity financing. Alternatively, debt

Trading
In general, the shares of a company may be transferred from shareholders to other parties by sale or other mechanisms, unless prohibited. Most jurisdictions have established laws and regulations governing such transfers, particularly if the issuer is a publicly traded entity.
The desire of stockholders to trade their shares has led to the establishment of stock exchanges, organizations which provide marketplaces for trading shares and other derivatives and financial products. Today, stock traders are usually represented by a stockbroker who buys and sells shares of a wide range of companies on such exchanges. A company may list its shares on an exchange by meeting and maintaining the listing requirements

Many large non-U.S companies choose to list on a U.S. exchange as well as an exchange in their home country in order to broaden their investor base. These companies must maintain a block of shares at a bank in the US, typically a certain percentage of their capital. On this basis, the holding bank establishes American depositary shares and issues an American depositary receipt

Small companies that do not qualify and cannot meet the listing requirements of the major exchanges may be traded over-the-counter (OTC) by an off-exchange mechanism in which trading occurs directly between parties. The major OTC markets in the United States are the electronic quotation systems OTC Bulletin Board (OTCBB) and OTC Markets Group (formerly known as Pink OTC Markets Inc.) where individual retail investors are also represented by a brokerage firm and the quotation service's requirements for a company to be listed are minimal. Shares of companies in bankruptcy proceedings are usually listed by these quotation services after the stock is delisted from an exchange.

There are other ways of buying stock besides through a broker. One way is directly from the company itself. If at least one share is owned, most companies will allow the purchase of shares directly from the company through their investor relations departments. However, the initial share of stock in the company will have to be obtained through a regular stock broker. Another way to buy stock in companies is through Direct Public Offerings which are usually sold by the company itself. A direct public offering is an initial public offering

drops below the margin requirement, at least 50% of the value of the stocks in the account. Buying on margin works the same way as borrowing money to buy a car or a house, using a car or house as collateral. Moreover, borrowing is not free; the broker usually charges 8–10% interest.
Selling
Selling stock is procedurally similar to buying stock. Generally, the investor wants to buy low and sell high, if not in that order ( short selling); although a number of reasons may induce an investor to sell at a loss, e.g., to avoid further loss.
As with buying a stock, there is a transaction fee for the broker's efforts in arranging the transfer of stock from a seller to a buyer. This fee can be high or low depending on which type of brokerage, full service or discount, handles the transaction.
After the transaction has been made, the seller is then entitled to all of the money. An important part of selling is keeping track of the earnings. Importantly, on selling the stock, in jurisdictions that have them, capital gains taxes will have to be paid on the additional proceeds, if any, that are in excess of the cost basis.
Short selling
Short selling consists of an investor immediately selling borrowed shares and then buying them back when their price has gone down (called "covering").[How an Investor Makes Money Short Selling Stocks](_blank)
Investopedia.com Essentially, such an investor bets that the price of the shares will drop so that they can be bought back at the lower price and thus returned to the lender at a profit.
Risks of short selling
The risks of short selling stock are usually higher than those of buying stock. This is because the loss can theoretically be unlimited since the stock's value can theoretically go up indefinitely.
Stock price fluctuations
The price of a stock fluctuates fundamentally due to the theory of supply and demand. Like all commodities in the market, the price of a stock is sensitive to demand. However, there are many factors that influence the demand for a particular stock. The fields of fundamental analysis and technical analysis attempt to understand market conditions that lead to price changes, or even predict future price levels. A recent study shows that customer satisfaction, as measured by the American Customer Satisfaction Index (ACSI), is significantly correlated to the market value of a stock. Stock price may be influenced by analysts' business forecast for the company and outlooks for the company's general market segment. Stocks can also fluctuate greatly due to pump and dump scams. Also see List of S&P 600 companies.
Share price determination
At any given moment, an equity's price is strictly a result of supply and demand. The supply, commonly referred to as the '' float'', is the number of shares offered for sale at any one moment. The demand is the number of shares investors wish to buy at exactly that same time. The price of the stock moves in order to achieve and maintain equilibrium. The product of this instantaneous price and the float at any one time is the market capitalization of the entity offering the equity at that point in time.
When prospective buyers outnumber sellers, the price rises. Eventually, sellers attracted to the high selling price enter the market and/or buyers leave, achieving equilibrium between buyers and sellers. When sellers outnumber buyers, the price falls. Eventually buyers enter and/or sellers leave, again achieving equilibrium.
Thus, the value of a share of a company at any given moment is determined by all investors voting with their money. If more investors want a stock and are willing to pay more, the price will go up. If more investors are selling a stock and there aren't enough buyers, the price will go down.
* Note: "For Nasdaq-listed stocks, the price quote includes information on the bid and ask prices for the stock."
That does not explain how people decide the maximum price at which they are willing to buy or the minimum at which they are willing to sell. In professional investment circles the efficient market hypothesis (EMH) continues to be popular, although this theory is widely discredited in academic and professional circles. Briefly, EMH says that investing is overall (weighted by the standard deviation) rational; that the price of a stock at any given moment represents a rational evaluation of the known information that might bear on the future value of the company; and that share prices of equities are priced ''efficiently'', which is to say that they represent accurately the expected value

of the stock, as best it can be known at a given moment. In other words, prices are the result of discounting expected future cash flows.
The EMH model, if true, has at least two interesting consequences. First, because financial risk

is presumed to require at least a small premium on expected value, the return on equity can be expected to be slightly greater than that available from non-equity investments: if not, the same rational calculations would lead equity investors to shift to these safer non-equity investments that could be expected to give the same or better return at lower risk. Second, because the price of a share at every given moment is an "efficient" reflection of expected value, then—relative to the curve of expected return—prices will tend to follow a random walk, determined by the emergence of information (randomly) over time. Professional equity investors therefore immerse themselves in the flow of fundamental information, seeking to gain an advantage over their competitors (mainly other professional investors) by more intelligently interpreting the emerging flow of information (news).
The EMH model does not seem to give a complete description of the process of equity price determination. For example, stock markets are more volatile than EMH would imply. In recent years it has come to be accepted that the share markets are not perfectly efficient, perhaps especially in emerging markets or other markets that are not dominated by well-informed professional investors.
Another theory of share price determination comes from the field of Behavioral Finance. According to Behavioral Finance, humans often make irrational decisions—particularly, related to the buying and selling of securities—based upon fears and misperceptions of outcomes. The irrational trading of securities can often create securities prices which vary from rational, fundamental price valuations. For instance, during the technology bubble of the late 1990s (which was followed by the dot-com bust of 2000–2002), technology companies were often bid beyond any rational fundamental value because of what is commonly known as the " greater fool theory". The "greater fool theory" holds that, because the predominant method of realizing returns in equity is from the sale to another investor, one should select securities that they believe that someone else will value at a higher level at some point in the future, without regard to the basis for that other party's willingness to pay a higher price.Thus, even a rational investor may bank on others' irrationality.
Arbitrage trading
When companies raise capital by offering stock on more than one exchange, the potential exists for discrepancies in the valuation of shares on different exchanges. A keen investor with access to information about such discrepancies may invest in expectation of their eventual convergence, known as arbitrage trading. Electronic trading has resulted in extensive price transparency (efficient-market hypothesis

) and these discrepancies, if they exist, are short-lived and quickly equilibrated.
