A stock market, equity market or share market is the aggregation of buyers and sellers (a loose network of economic transactions, not a physical facility or discrete entity) of stocks (also called shares), which represent ownership claims on businesses; these may include securities listed on a public stock exchange as well as those only traded privately. Examples of the latter include shares of private companies which are sold to investors through equity crowdfunding platforms. Stock exchanges list shares of common equity as well as other security types, e.g. corporate bonds and convertible and non convertible bonds and many more.
Introduction of Share Market
Option & Professional Trading
A stock exchange is a place where, or an organization through which, individuals and organisations can trade stocks. Many large companies have their stock listed on a stock exchange. This makes the stock more liquid and thus more attractive to many investors. It may also act as a guarantor of settlement. Other stocks may be traded “over the counter” (OTC), that is, through a dealer. Some large companies will have their stock listed on more than one exchange in different countries, so as to attract international investors.
Stock exchanges may also cover other types of securities, such as fixed interest securities (bonds) or (less frequently) derivatives, which are more likely to be traded OTC.
Tobias Preis and his colleagues Helen Susannah Moat and H. Eugene Stanley introduced a method to identify online precursors for stock market moves, using trading strategies based on search volume data provided by Google Trends. Their analysis of Google search volume for 98 terms of varying financial relevance suggests that increases in search volume for financially relevant search terms tend to precede large losses in financial markets.
