Raising capital for businesses
The Stock Exchange provide companies with the facility to raise capital for expansion through selling shares to the investing public
Mobilizing savings for investment
When people draw their savings and invest in shares, it leads to a more rational allocation of resources because funds, which could have been consumed, or kept in idle deposits with banks, are mobilized and redirected to promote business activity with benefits for several economic sectors such as agriculture, commerce and industry, resulting in stronger economic growth and higher productivity levels of firms.
Facilitating company growth
Companies view acquisitions as an opportunity to expand product lines, increase distribution channels, hedge against volatility, increase its market share, or acquire other necessary business assets. A takeover bid or a merger agreement through the stock market is one of the simplest and most common ways for a company to grow by acquisition or fusion.
Profit sharing
Both casual and professional stock investors, through dividends and stock price increases that may result in capital gains, will share in the wealth of profitable businesses.
Corporate governance
By having a wide and varied scope of owners, companies generally tend to improve on their management standards and efficiency in order to satisfy the demands of these shareholders and the more stringent rules for public corporations imposed by public stock exchanges and the government. Consequently, it is alleged that public companies (companies that are owned by shareholders who are members of the general public and trade shares on public exchanges) tend to have better management records than privately-held companies (those companies where shares are not publicly traded, often owned by the company founders and/or their families and heirs, or otherwise by a small group of investors). However, some well-documented cases are known where it is alleged that there has been considerable slippage in corporate governance on the part of some public companies. The dot-com bubble in the early 2000s, and the subprime mortgage crisis in 2007-08, are classical examples of corporate mismanagement. Companies like Pets.com (2000), Enron Corporation (2001), One.Tel (2001), Sunbeam (2001), Webvan (2001), Adelphia (2002), MCI WorldCom (2002), Parmalat (2003), American International Group (2008), Lehman Brothers (2008), and Satyam Computer Services (2009) were among the most widely scrutinized by the media.
Creating investment opportunities for small investors
As opposed to other businesses that require huge capital outlay, investing in shares is open to both the large and small stock investors because a person buys the number of shares they can afford. Therefore the Stock Exchange provides the opportunity for small investors to own shares of the same companies as large investors.
Government capital-raising for development projects
Governments at various levels may decide to borrow money in order to finance infrastructure projects such as sewage and water treatment works or housing estates by selling another category of securities known as bonds. These bonds can be raised through the Stock Exchange whereby members of the public buy them, thus loaning money to the government. The issuance of such bonds can obviate the need to directly tax the citizens in order to finance development, although by securing such bonds with the full faith and credit of the government instead of with collateral, the result is that the government must tax the citizens or otherwise raise additional funds to make any regular coupon payments and refund the principal when the bonds mature.
Barometer of the economy
At the stock exchange, share prices rise and fall depending, largely, on market forces. Share prices tend to rise or remain stable when companies and the economy in general show signs of stability and growth. An economic recession, depression, or financial crisis could eventually lead to a stock market crash. Therefore the movement of share prices and in general of the stock indexes can be an indicator of the general trend in the economy.
