1、Overview of Market StructureThe Securities and Exchange Commission (SEC) was created in 1934. Stock exchanges are regulated by the SEC, but they are considered self-regulatory organizations (SROs) with considerable latitude. The major national stock exchanges are the New York Stock Exchange (NYSE) a
2、nd the American Stock Exchange (AMEX). In 1998, the National Association of Security Dealers (NASD) acquired the AMEX. It then sold the AMEX in 2003 to a private equity group for only $110 million.The NASD regulates an electronic trading network called the NASDAQ (NASD Automated Quote System). The N
3、ASD went public in 2001, trades under the symbol NDAQ and is now called the Nasdaq Stock Market Incorporated. A funny name for an exchange that is not a stock market (at least according to the SEC).1知识书苑The New York Stock ExchangeStock markets like the New York Stock Exchange provide strict criteria
4、 for shares to be traded on their exchange. For this reason, they are still called listed securities.NYSE Facts and Figures:U.S. listing requirementsDaily trading volumeMarket capitalization10 Largest Companies2知识书苑The NYSE Trading FloorVirtual tour3知识书苑NYSE ParticipantsTo gain access to the floor,
5、you must buy a seat. The number of seats has remained at 1,366 since 1953. They currently sell for about $1.5 million. Each stock listed on the NYSE is allocated to a specialist, a market maker who trades only in specific stocks at a designated location. All buying and selling of a stock occurs at t
6、hat location, called a trading post. Buyers and sellers -represented by the floor brokers - meet openly to find the best price for a security. 4知识书苑The NYSE Auction ProcessSpecialists organize the auction process on the trading floor. They provide information about the current state of the market, t
7、he price at which shares can be bought (bid) or sold (offer or ask) and the quantity of shares available at each price, called depth. The difference between the bid and offer is called the spread.

The specialist has an affirmative obligation to stabilize marke
9、ts during severe market downturns, like the market crash of October 19, 1987. The vast majority (77%) of NYSE volume is a result of public order meeting public order - individuals, institutions and member firms interacting directly with each other. Non-specialists handle 14% and specialists 10%.Note
10、: There can be a conflict between the specialist acting as both principal and agent.6知识书苑NYSE Specialist FirmsThe largest NYSE specialist firm is LaBranche and Co. which handles more than 500 stocks. Spear, Leeds and Kellog (acquired by Goldman Sachs in 2000 for $6.5 billion) and Fleet Meehan are se

Together, these 3 firms trade about 2/3 of the daily volume.You can find a complete list on the here.7知识书苑NYSE Order Book8知识书苑Types Of Orders - NYSEThese are four kinds or orders: (1)market orders: an order to buy or sell a fixed quantity at the current market
12、 price; (2)limit orders: an order to buy or sell a fixed quantity at a designated price; (3)stop order: an order to buy or sell once a designated “stop” price has been hit.(4)stop-limit orders: a combination of a limit and a stop order On the NYSE, stop orders become market orders once a trade has b

The stock is VZ and Spear Leads and Kellogg (SLKS) was the specialist.The book also included market orders to buy 3,300 shares and market orders to sell 2,100 shares.The specialist could have paired off the market buy and sel
17、l orders and satisfied the remaining order from his account or against the limit orders at 41.10 and 41.12.Instead, the specialist shorted 3,300 shares at 41.10, 400 shares at 41.04, 200 shares at 41.03, bringing the spread to 41.00 X 41.10. At that price, he covered 2,100 shares from the market sel
18、l orders, earning a riskless profit on that portion of the trade.13知识书苑Grassos CompensationDuring his tenure as chairman and CEO of the NYSE, Richard Grasso, who had started out as a clerk of the floor, received nearly $160 million in compensation.The Webb report has all the details.Eliot Spitzer ha
19、s sued Grasso to recover some of his pay package.The bottom line: the specialist stocks are down, trading volume is down, electronic exchanges are eroding NYSE market share, NYSE seat prices are down to $1 million from a 1999 peak of $2.5 million. Mutual funds like Fidelity are actively exploring al
20、ternatives to the NYSE.Grasso was essentially being paid hush money to protect the specialists.My speculation: The NYSE is the only remaining large floor based trading system in the world. 5 years from now, it, like London, may no longer exist. Nonetheless, the power of this institution is huge and
21、it will fight to protect its monopoly.14知识书苑NYSE Goes PublicIn the Spring of 2005, the NYSE made two bold moves that are the most radical in its history:(1)NYSE ends its partnership structure and will go public.(2) NYSE will acquire an electronic exchange called Archipelago.NYSE comments.Archipelago

24、s dealers trading more than 15,000 different issues. These traders are called market makers. Nasdaq operates what it calls the National Market (NNM) for larger capitalization stocks and a smaller cap market called the Nasdaq SmallCap market. There is an over the counter service called the “OTC Bulle
25、tin Board (OTCBB).” OTCBB has no formal relationship with the Nasdaq.17知识书苑NASDAQ OwnershipNasdaq was owned until 2001 entirely by its member firms. Nasdaq issued stock that to its members that has been gradually acquired by an independent body called the Nasdaq Stock Market, Inc. which now trades o
26、n the NNM under the symbol NDAQ. The NASD has re-organized as a private, not for profit regulatory body. It has so far been more diligent than the NYSE in oversight of its members.VolumeFacts and Figures:3,271 listingsListing requirementsNasdaq 100 by market cap18知识书苑NASDAQ ParticipantsApproximately
27、 600 market makers ranging from large investment banks like Goldman Sachs (GSCO), to retail oriented operations like Knight Trimark (NITE) to small firms like Glen Rauch Securities (GRSI). There are now just 3 ECNs: Nasdaq+BRUT, INET, and ARCA19知识书苑Nasdaq Merger with InstinetNasdaq has responded to
28、ECN competition and the NYSEs move into electronic trading by trying to grab market share.They acquire the BRUT ECN in 2004.They also proposed a merger with Instinet in the Spring of 2005.Instinet had merged with a popular day trading ECN called Island in 2003.Instinet will give Nasdaq the ability t
29、o trade NYSE stocks. For the first time, there is a direct competitor to NYSE. On the other hand, ARCA will give the NYSE the ability to trade Nasdaq issues.20知识书苑The Nasdaq Limit Order BookThis is the total view display which shows multiple levels of liquidity from market participants. For example,
30、 Morgan Stanley (MSCO) is on the bid at both 19.98 and 19.97.The Level I quote is 19.98 x 19.99 with depths of 21 and 10, the largest at the inside.Most of Nasdaq execution systems have been folded into SuperMontage.21知识书苑SuperMontageNASDAQ SuperMontage is a fully integrated order display and execut
31、ion system for all NASDAQ National Market and SmallCap securities. SuperMontage is a voluntary, open-access system that accommodates diverse business models and trading preferences.SuperMontage allows market participants to enter unlimited quotes and orders at multiple price levels. Quotes and order
32、s of all SuperMontage participants are integrated and displayed on market participants front-ends as well as via data feeds. The system displays aggregate interest five price levels deep on each side of the market on a dynamic basis and additional price levels on a non-dynamic basis. SuperMontage pa

This means broadly that information is incorporated into stock prices.This implies that fundamental analysis, technical ana
37、lysis and other approaches to the market do not produce abnormal returns.We will present some evidence for and against market efficiency. The evidence against is the bubbles and crashes we have observed in markets.The evidence for is the poor performance of profession mutual fund managers. To give t
38、his evidence some context, we first have to discuss some basic valuation models for the market.27知识书苑Valuation ModelsMany models assume that stock prices are a present discounted value of the future dividendsIf dividends were constant, this simplifies toIf dividends were growing at a constant rate g
39、The solution here is28知识书苑Bubbles?29知识书苑Peaks And CrashesThe Dow Jones average did not return to its 1929 peak until 1954.Japans Nikkei index peaked at 40,000 on January 1, 1990 and currently trades atThe Nasdaq Composite peaked at 5,000 in March of 2000 and still trades almost 3,000 points below th
40、at level.Nonetheless, a well diversified portfolio of common stocks has returned nearly 6% in real terms over the last 200 years. Bonds have returned only 2%. This difference is called the equity premium. This argument has been promoted by Jeremy Siegel, author of Stocks for the Long Run.30知识书苑Irrat
41、ional Exuberance?The counter argument to Siegels view has come from Yale University professor Robert Shiller, author of Irrational Exuberance.Shiller claims that the market is overvalued compared to its historical levels.31知识书苑Real EarningsAn even stronger arguments comes from comparing real earning
42、s and real stock prices.The Shiller-Siegel debate is ongoing.32知识书苑(Under) Performance of Mutual FundsMark Carhart, now at Goldman Sachs, has shown (“On Persistence in Mutual Fund Performance,” Journal of Finance, 1997.) that over the 34-year period from 1962 to 1995, only 23% of funds outperformed
43、the S&P 500 index. 33知识书苑Dont Chase Mutual Fund WinnersCarhart makes a second point which is even less well understood. Funds with high returns tend to have high returns only in the year following their outperformance. This is just the momentum result we saw in individual stocks.After one-year, thei
44、r performance is just average.Fidelity Magellan, under Peter Lynch, and Legg Mason Value, under Bill Miller, have had long periods where they outperform the index.Are they just winners in a big coin flipping competition?Recent returns for Magellan suggest that may be the case.34知识书苑The Role of Secur
45、ity AnalystsAccording to the SEC, the role of analysts: “research analysts study publicly traded companies and make recommendations on the securities of those companies.Analysts have been in the news lately for not fulfilling their fiduciary duty to investors. If we understand their incentives, we c
46、an understand the problems they have faced.Analysts are not directly revenue producers for securities firms. They are a cost center, not a profit center. Yet we know they are well paid.How do they earn their money?(1) By attracting brokerage business to their firms.(2) Through investment banking bus

Jack Grubman attended WorldCom board meetings and was paid consulting fees.36知识书苑ReformsReg FDOn August 10, 2000, the SEC approved Regulation Fair Disclosure (Reg FD), which became effective on October 23rd of the same year. According to Eric Zitzewitz of Stanford Business School: This regulation
50、prohibits the selective disclosure of material information to financial professionals including analysts; companies with material information to disclose must now do so in a press release or conference call that is simultaneously open to all investors.”Spitzer investigationsMay 2002 settlement with
