Definitions and Basics
The price of a share of stock, like that of any other financial asset, equals the present value of the sum of the expected dividends or other cash payments to the shareholders, where future payments are discounted by the interest rate and risks involved. Most of the cash payments to stockholders arise from dividends, which are paid out of earnings and other distributions resulting from the sale or liquidation of assets....Bonds, from the Concise Encyclopedia of Economics
Bond markets are important components of capital markets. Bonds are fixed-income financial assets--essentially IOUs that promise the holder a specified set of payments. The value of a bond, like the value of any other asset, is the present value of the income stream one expects to receive from holding the bond....Efficient Capital Markets, from the Concise Encyclopedia of Economics
The efficient markets theory (EMT) of financial economics states that the price of an asset reflects all relevant information that is available about the intrinsic value of the asset. Although the EMT applies to all types of financial securities, discussions of the theory usually focus on one kind of security, namely, shares of common stock in a company. A financial security represents a claim on future cash flows, and thus the intrinsic value is the present value of the cash flows the owner of the security expects to receive....In economics the word "investment" does not mean buying stocks and bonds! Investment, from the Concise Encyclopedia of Economics
By investment, economists mean the production of goods that will be used to produce other goods. This definition differs from the popular usage, wherein decisions to purchase stocks or bonds are thought of as investment.

Insider Trading, from the Concise Encyclopedia of Economics
"Insider trading" refers to transactions in a company's securities, such as stocks or options, by corporate insiders or their associates based on information originating within the firm that would, once publicly disclosed, affect the prices of such securities. Corporate insiders are individuals whose employment with the firm (as executives, directors, or sometimes rank-and-file employees) or whose privileged access to the firm's internal affairs (as large shareholders, consultants, accountants, lawyers, etc.) gives them valuable information. ...Pensions, from the Concise Encyclopedia of Economics
A private pension plan is an organized program to provide retirement income for a firm's workers. Some 56.7 percent of full-time, full-year wage and salary workers in the United States participate in employment-based pension plans (EBRI Issue Brief, October 2003)....
A Little History: Primary Sources and References
The Bond Market Association estimates that U.S. corporations had more than $4.5 trillion in bonds outstanding at the end of 2003, with debt averaging about 50 percent of equity (the value of the stock) from 1994 through 2003. Thus, corporations depend heavily on debt financing. One question that market participants or academic observers have not answered adequately, however, is how companies determine what fraction of their corporate activities should be funded through borrowing and what fraction through issuing stock.
The legendary John Bogle, founder of the Vanguard Group and creator of the index mutual fund, talks about the Great Depression, the riskiness of bond funds, how he created the Index 500 mutual fund—now the largest single mutual fund in the world—how the study of economics changed his life and ours, and Sarbanes-Oxley. At the end of the conversation, he reflects on his life and career....How mutual funds work: Good Timing: A Mutual-Fund "Scandal"?, by Fred S. McChesney. Econlib, January 5, 2004
Mutual funds perform several functions for investors, and do so through different kinds of funds. Specialized (e.g., high-tech, energy-company) funds research opportunities for investors, and invest in specific sectors accordingly. Index funds hold a diversified portfolio of different stocks that replicates the entire equity market rather than particular sectors.Enron's collapse and subsequent legislation: Sarbanes-Oxley (SOX), Belts and Suspenders: The Regulatory Aftermath of the Corporate Accounting Scandals, by Richard Mahoney. Econlib, February 2, 2004.
The market drop had another result, potentially more damaging. A dozen or more companies, the most prominent of which was Enron, were alleged to be "cooking the books"—inflating earnings in an attempt to keep stock prices up in a rapidly declining market. Other complaints against various companies included alleged self-dealing insider schemes and lavish personal use of shareowner assets....Futures and Options Markets, from the Concise Encyclopedia of Economics
In the late 1970s and early 1980s, radical changes in the international currency system and in the way the Federal Reserve managed the U.S. money supply produced unprecedented volatility in interest rates and currency exchange rates. As market forces shook the foundations of global financial stability, businesses wrestled with heretofore unimagined challenges. Between 1980 and 1985, Caterpillar, the Peoria-based maker of heavy equipment, saw exchange-rate shifts give its main Japanese competitor a 40 percent price advantage. Meanwhile, even the soundest business borrowers faced soaring double-digit interest rates. Investors clamored for dollars as commodity prices collapsed, taking whole nations down into insolvency and ushering in the Third World debt crisis....Junk Bonds, from the Concise Encyclopedia of Economics
Junk bonds, also known less pejoratively as high-yield bonds, are bonds that are rated as "speculative" or "below investment" grade issues: below BBB for bonds rated by Moody's and below Baa for bonds rated by Standard and Poor's (the two main debt-rating agencies). Bond ratings measure the perceived risk that the bonds' issuer will not make interest payments or repay the principal at maturity. The riskier a bond is, other things being equal, the lower its rating. The highest-rated nondefaulted bonds are rated AAA or Aaa, and the lowest are rated C, with defaulted bonds rated D; thus, junk bonds can be rated anywhere between Baa (BB) and D. As junk bonds are perceived to be riskier than other types of debt, they typically trade at higher yields--that is, higher rates of return--than investment-grade bonds. ...Program Trading, from the Concise Encyclopedia of Economics
Program trading, the subject of considerable controversy in recent years, is the simultaneous trading of a portfolio of stocks, as opposed to buying or selling just one stock at a time. The New York Stock Exchange defines program trading as any trade involving fifteen or more stocks with an aggregate value in excess of $1 million....Takeovers and Leveraged Buyouts, from the Concise Encyclopedia of Economics
Corporate takeovers became a prominent feature of the American business landscape during the seventies and eighties. A hostile takeover usually involves a public tender offer—a public offer of a specific price, usually at a substantial premium over the prevailing market price, good for a limited period, for a substantial percentage of the target firm's stock. Unlike a merger, which requires the approval of the target firm's board of directors as well as voting approval of the stockholders, a tender offer can provide voting control to the bidding firm without the approval of the target's management and directors.Merton Miller, biography from the Concise Encyclopedia of Economics
Miller's contribution was the Modigliani-Miller theorem, which he developed with Franco Modigliani while both were professors at Carnegie Institute of Technology. (Modigliani had earned the prize in 1985 for his life-cycle model of saving and for the Modigliani-Miller theorem.)
