This may include the following: Raising capital for businesses Besides the borrowing capacity provided to an individual or firm by the banking system, in the form of credit or a loan, a stock exchange provides companies with the facility to raise capital for expansion through selling shares to the investing public. Capital intensive companies, particularly high tech companies, typically need to raise high volumes of capital in their early stages. For this reason, the public market provided by the stock exchanges has been one of the most important funding sources for many capital intensive startups. In the 1990s and early 2000s, hi-tech listed companies experienced a boom and bust in the world's major stock exchanges. Since then, it has been much more demanding for the high-tech entrepreneur to take his/her company public, unless either the company is already generating sales and earnings, or the company has demonstrated credibility and potential from successful outcomes: clinical trials, market research, patent registrations, etc. This is quite different from the situation of the 1990s to early-2000s period, when a number of companies (particularly Internet boom and biotechnology companies) went public in the most prominent stock exchanges around the world in the total absence of sales, earnings, or any type of well-documented promising outcome. Though it's not as common, it still happens that highly speculative and financially unpredictable hi-tech startups are listed for the first time in a major stock exchange. Additionally, there are smaller, specialized entry markets for these kind of companies with stock indexes tracking their performance (examples include the Alternext, CAC Small, SDAX, TecDAX). Alternatives to stock exchanges for raising capital Alternative investment funds refer to funds that include hedge funds, venture capital, private equity, angel funds, real estate, commodities, collectibles, structured products, etc. Alternative investment funds are an alternative to traditional investment options (stocks, bonds, and cash). Research and Development limited partnerships Companies have also raised significant amounts of capital through R&D limited partnerships. Tax law changes that were enacted in 1987 in the United States changed the tax deductibility of investments in R&D limited partnerships. In order for a partnership to be of interest to investors today, the cash on cash return must be high enough to entice investors. Venture capital A general source of capital
