Part II: Security Markets: Part II: Security Markets Topic 8 - Stock Markets
Equity Claims in Capital Markets: Equity Claims in Capital Markets Residual Claimants: Shareholders or equity owners
Are the legal owners of the firm
Have limited liability (losses are limited to the amount of the investment)
Have voting rights – elect the directors who hire/fire management
Otherwise are have little control and are passive in their participation of management
Dividends: equivalent to the coupon payment of a bond, except…
There is no promise of the amount of frequency
Are taxed twice (at the corporate level and at the personal level)
Maturity: Equity claims are infinitely lived
Unless a firm repurchases shares, investors never do not get their initial return back
Most investors anticipate a “capital” return which is untaxed until sold, which is often prefferred to dividends
Secondary markets allow investors to “cashout”

Role of Primary Markets: Role of Primary Markets Serve to reduces the adverse selection process in raising capital
Underwriters (investment banks) certify firm type by taking firms public (IPO)
Rating agencies certify debt issues
Government provides strict framework for the registration process
Reduces search costs – intermediaries (underwriters) find investors
Large institutions
Wealthy clients
Active household investors
How does this relate to perfect capital markets (PCM)?
Rational expectations a well-defined registration process with government supervision allows investors to have more homogenous beliefs
Transactions costs Lower search costs reduces market frictions, and reputable underwriters communicate information efficiently
Role of Secondary Markets: Role of Secondary Markets Liquidity: Investors trade time and risk, buying and selling financial instruments prior to maturity
Search costs: Central trading locations reduce search costs
Information production
Continuous trading – assets are priced daily
Low cost - look for stock price online
Market discipline: addresses moral hazard issue of a firm changing type
Financial markets (FM) – react to “bad” news with lower stock prices
Market for corporate control (MCC)– lower stock prices make firms “good” targets for takeover
Types of secondary markets: Types of secondary markets Exchanges: (NYSE, AMEX, Regional, CBOE, London Gold Exchange)
A central location (trading floor) where the exchange of financial securities takes place
Central agents match buyers and sellers (one point of contact)
Over-the-counter (OTC): eg. Nasdaq
A geographically dispersed trading forum where traders are linked through telecommunications (computer) systems
Infinite number of communications pathways (no single point of contact)
Secondary Market structures: Secondary Market structures Call Market (Walrasian auction): Orders are batched together for simultaneous execution
Auctioneer determines the market clearing price prior to trading in the following manner:
Auctioneer proposes a price
Representatives (buyers and sellers) privately indicate whether or not they are a buyer or seller at that price.
If equilibrium (net buys = net sells) is not reached, then auctioneer proposes adjusted price.
Process continues until auctioneer finds the market clearing price.
Once this price is determined, then all trades occur simultaneously
Free rider problem: All private information is revealed prior to trading since trading does not occur until a market clearing price is revealed. The price moves to equilibrium prior to the first trade, so even uninformed investors benefit (free-ride) off the private information of informed investors.
London Gold Bullion market is a call market – prices set twice daily.
Continuous (Auction) Market:
Most common market in the electronic age.
Prices are determined continuously throughout the trading hours as buyers submit their buy and sell orders.
Secondary Market Participants: Secondary Market Participants Investors: buyers and sellers of securities (households and financial institutions)
Brokers: Earn commissions by serving as an agent on behalf of the buyer or seller (real estate agent, mortgage broker, stock broker)
Dealers: Take inventory on their own account in a traded asset to facilitate trading (car dealer, investment or commercial bank)
Broker-dealers: act as agents in addition to holding inventory and trading on their own account
Market-Makers: A dealer that is tasked with keeping the market running smoothly, and may be a privileged/regulatory activity (NYSE specialist)
Stock Market Participants: Stock Market Participants Common Stock Markets: Stock markets that trade the securities of public firms are perhaps the most easily recognizable financial secondary markets.
Investors: buyers and sellers of common stock
Brokers: transmit investor orders (E*Trade, Schwab, Fidelity, Merrill Lynch, Ameritrade etc.)
Dealers: trade on their own account (Goldman Sachs, Morgan Stanley, JP Morgan, Merrill Lynch & other investment banks)
Market Makers: Dealer-brokers who are required to trade to keep market moving smoothly (NASD member firms and NYSE specialists). Market makers profit through two avenue streams:
Order matching – earns commission by acting as an agent to the investor
Taking a position – earns the bid-ask spread by acting as a dealer (principal/owner)
In an idealized market, Market makers would need only match orders and charge a small fee. However, if trade imbalances occur (more buys than sells or vice-versa), then the market-maker is required to take a position to smooth trading.

Brokers, Dealers and Market Makers: Brokers, Dealers and Market Makers Brokers, dealers, broker-dealers and market makers enter the market to reduce the trading costs incurred by investors
Easier to buy a new car from a dealer with a car-lot of 1,000 cars than visiting the same number of cars at the individual residences of private sellers
Dealers can stand ready to buy on a moments notice, enhances liquidity.
Brokers match buyers and sellers that might not otherwise find each other (real estate agents can pull up listing on the MLS and quickly show a buyer available properties)
Bid-Ask spreads: Bid-Ask spreads Bid-Ask Spread: Is the difference in price between what the market maker is willing to buy and sell a security, and is compensation for the market-maker assuming the risks associated with holding inventory in the security.
Bid Price: Price dealer pays investors or price investors receive from dealers.
Ask Price: Price dealer receives from investors or price investor pays dealer.
Spread = Ask - Bid
The size of the spread is indicative of the amount of risk associated with ownership in the security, including:
Liquidity risk (time required to unwind a position)
Security price uncertainty (highly volatile firms)
Trading against informed investors
Bid-Ask spreads increase with risk, particularly when a security is illiquid, volatile or there
is a threat that insiders (informed investors) are trading on private information
Slide15: Security A Security B Security B has a larger spread: Relative to Security A, B likely has (1) more risk, (2) more informed traders, or is less liquid.
Common Stock Exchanges: Common Stock Exchanges Market Structure: e.g. NYSE, AMEX
Operate using the auction system with a single market maker (in most cases) for each traded security
Membership:
Market makers must be member of the exchange. Members pay for the right to trade in a security (buy a seat on the exchange).
Not all seats are created equal – The right to trade IBM shares may be more profitable than the right to trade 7-Eleven
Regulation & listing rules:
Exchanges are regulated by the SEC according to the Securities Exchange Act of 1934. Exchanges like the NYSE are also self-regulating organizations (SRO), performing many of the monitoring activities to ensure credible markets. This does not prohibit the NYSE from profiting (NYSE is not a non-profit organization)
Exchanges have minimum listing requirements such as minimum stock price, market value and trading volume. These are imposed mainly to ensure that sufficient revenue can be earned by the market-maker.
Firms need not be exclusive with their listing, and can list shares on a regional and/or foreign exchange in addition to listing nationally. In each case, the firm must meet the listing requirements of the exchange.
New York Stock Exchange (NYSE)(a.k.a. the “Big Board”): New York Stock Exchange (NYSE) (a.k.a. the “Big Board”) Is the biggest and most prestigious national exchange with 2,800 listed companies and a market value of $13.3 Trillion (13/30/05).
The NYSE has 1366 exchange members (seats) which themselves trade at prices upwards of 2 million dollars. These firms collectively own the exchange; however, they do not run the exchange
Seat holders are allowed to buy and sell securities on the exchange floor without paying commissions
New York Stock Exchange (NYSE): New York Stock Exchange (NYSE) NYSE Characteristics:
Average trading volume is about 1 billion shares per day
About half of the NYSE members are commission brokers, while the other half is specialists/market makers
The market opens each day as a call market (specialist sets market clearing price), and then operates as a continuous auction throughout the rest of the trading day
Each firm traded on the exchange is assigned only one specialist, but a specialist can be assigned more than one security/firm
Each specialist has a private limit order book in which they have the demand schedule for all buyers and sellers (price & quantity). Their first obligation is to match orders, and only if necessary, trade on their own inventory
80% of all trades done by a specialist or order matches, 20% are trades on their own inventory.
If trade imbalances get too large, beyond the capacity of the market maker to facilitate smooth trading, then trade suspension may occur. This occurs more often than you think, particularly around merger announcement or large private information events. If the Specialist observes unusual activity, then trading can be suspended.
NYSE Delisting: NYSE Delisting NYSE delisting can occur if:
There are fewer than 400 total security holders
There are less than 1,200 total holders and average month-end volume is 100,000 shares
Fewer than 600,000 shares in public hands
Market cap less than $8 Million
Market cap or tangible assets less than $12 Million and NI less than 600,000
Comment: Reverse stock splits are often performed to meet exchange requirements.
Over the Counter (OTC) markets: Over the Counter (OTC) markets Over-the-counter stock markets: NASDAQ (National Association of Securities Dealers Automated Quotations system) was established in 1971 as a subsidiary of the NASD (National Association of Securities Dealers)
Trades over 3,800 stocks (Market cap of $3.6 Trillion – 12/31/05) on a virtual trading floor – a network of computer systems – and over 500 market makers.
Market characteristics
Negotiated system with Multiple Market Makers – as many as 20 market makers may list quotes on Microsoft (MSFT).
Although smaller aggregate market cap, share volume on the Nasdaq larger than NYSE, with almost 500 billions shares traded annually.
There are listing requirement for NASDAQ firms, but even so, this is referred to as the “unlisted” firm market, because initially the NASDAQ served those firms that could not list on an exchange. Historically, firms would switch to the NYSE from NASDAQ when they were sufficiently mature, but since the late 1980’s, many firms remained, particularly in the high-tech sectors (Microsoft, Oracle, Cisco etc.). Now the NASDAQ is on par with the NYSE.
Market makers post bid-ask spreads, but are only required to fill those quotes up to 1,000 shares, so doing so in not costly relative to the risks of a specialist.
Nasdaq is actually two separate markets: Nasdaq National Market (NNM) and Nasdaq small cap market.
Electronic Communication Networks (ECNs): Electronic Communication Networks (ECNs) ECNs electronic communications exchanges (Island, Instinet, Archipelago, MarketXT etc.) are a relatively recent financial innovation
ECNs were initially formed as a private network to execute trades, but have since been popularized with competitive pricing
NASDAQ was opened to ECN’s in late 1990’s which spurred their growth. ECN orders are transmitted to NASDAQ and are displayed along side market makers
ECNs are not market makers, do not act as a dealer holding inventory, but simply broker order matching. Investors can trade directly with one another through an ECN, by passing the regular market structure
ECN’s now have 30% of NASDAQ trading volume, 5% of NYSE
Execute after hour trades (past 4PM Eastern time) – greater than 70 million shares a day
Institutional Trading: Institutional Trading Block Trades: Trades greater than 10,000 shares and a Market Value of $200,000
1961: 9 block trades per day (3% of NYSE volume)
1999: 16,600 block trades per day (50% of NYSE volume, 24.6% of NASDAQ)
Program Trades: When a buyer wants to purchase a number of different stocks at the same time
NYSE definition is at least 15 stocks at a market value of $1 million
Institutions with diverse portfolios often care about firm characteristics, and not specific firm, hence “baskets” of stocks trading with lower transactions costs are attractive
Upstairs market: Trading desks at major securities firms are linked electronically to make trades among themselves, off of the exchange floor, and not through a market maker or specialist.
Trading Mechanics: Trading Mechanics Market Order: An order to be executed at the best price available in the market
The order with the best price is always executed first for buying and selling
When orders are submitted to the market at the same price, the rule is first-in first-executed. However, public orders always supercede dealer orders at the same price when dealers are trading on their own account (public orders executed first).
Risk of a market order is that the price is unknown at the time of submission. The investor specifies the number of shares to buy or sell, and then accepts the best price available.
Conditional Orders: Designates a price threshold for the execution of a trade.
Limit orders:
Buy limit order – the stock may be purchased only at a designated price or lower
Sell limit order – the stock may be sold only at a designated price or higher
Stop orders:
Buy stop order – the stock is purchased only after the price rises to a designated price.
Sell stop order – the stock is sold only if the price falls to a designated price.
Protects investors from adverse price changes at the time of order
Does not guarantee that the order will take place.
Limit order examples: Limit order examples Acme Lubbock Inc is currently trading at $92.
The following are possible limit orders:
buy limit order at $85 – Investor will buy only if the share price drops to $85 or lower
sell limit order at $99 – Investor will sell if the share price rises to $99
buy stop order at $99 – Investor will buy once the price rises to $99
sell stop order at $85 – Investor will sell if the share price drops to $85
Trading Mechanics: Trading Mechanics Fill or Kill: Order must be executed when it reaches the market (usually within a day, but usually shorter)
Open Order: This order is good until the investor cancels it, but no more than 3 months.
Odd Lot: < 100 shares. Firms often try to buy-out owners of odd lots since shareholders impose significant expense to the firm. Firm must send out annual reports and proxy statements to each owners of the firm. And these costs might be more than the aggregate investment value of an odd lot.
Round Lot: 100 share multiple
Short Selling: Short Selling Selling borrowed shares (securities not owned by the investor at the time of sale).
short selling is a vital component to maintaining market efficiency. It allows downward price pressure to over-valued securities that might not otherwise incorporate new information if left only to the discretion of current shareholder.
Borrowing shares is effectively taking out a loan. The short seller pays interest on borrowed shares until they are eventually returned (position covered).
Example: Investor sells short 100 shares of IBM at $90/share
Investor borrows shares from an IBM shareholder (could be a brokerage that is holding shares on behalf of an IBM shareholder)
Investor pays interest on shares borrowed, worth $9,000 at the time of borrowing. This accumulates daily.
Investor sells the shares at the market price of $90 and now has $9,000 in cash.
----- The shares must eventually be returned to the original IBM shareholder ----
Investor returns to the market and buys 100 shares at the new prevailing price, and returns the shares.
Short Selling: Short Selling If the price falls (drops) during the time the shares were sold short, then the investor buys them back at a reduced price and pockets the difference.
sold short 100 shares at $90 = collects $9,000
covered short position by buying back shares at $80 one week later = pays $8,000
Investor is left with $1,000 profit after returning the shares
Short selling constraints:
Short selling constraints occur when there is so much short interest (short sellers taking positions), that it is hard to find shares to borrow
The short selling transaction, borrowing interest, is settled daily
The original shareholder of stock (or intermediary holding the stock) can demand the shares back at any point in time, requiring the short seller to cover the position
There is no centralized market for selling short, so the process may be inefficient
Short selling constraints are believed by many to be one contributing factor for over valued share prices like we saw in the dot.com era.
Margin Trading: Margin Trading Trading on Margin: When an investor borrows money to buy securities.
By levering an investment (financial leverage), and investor can earn greater than the market rate of return. This is done by borrowing money and investing into the market as depicted in the diagram above
Example: Investor places $10,000 into a brokerage account to by shares of Acme Lubbock Inc at $100/share
No leverage: Investor A purchases 100 shares worth $10,000.
Leverage: Investor B purchases 200 shares, borrowing $10,000 for the extra shares
If price increases by $10 then investor B receives a higher return
RA = $10/share*100 shares = $1,000, $1,000/$10,000 = 10%
RB = $10/share*200 shares = $2,000, $1,000/$10,000 = 20%
The opposite is true for a $10 decline
If the price drops $50/share, then investor B loses 100% of his initial equity while investor A loses 50%.
Margin Trading and the Efficient Frontier: Margin Trading and the Efficient Frontier Margin trading can facilitate efficient markets by creating investment opportunities that might not otherwise be available.
Margin Maintenance: Margin Maintenance Margin Maintenance: The FED controls how much equity must be maintained by margin traders. During the bubble years, it was 35%, but now it is 50%.
Equity = (total value of investment – amount borrowed) / total value of investment.
In the previous example, investor B has (20,000–10,000)/20,000 = 50% (the current limit)
Margin Call: When an investor drops below, the current margin limit, the brokerage requires:
additional cash put into the account
liquidation of securities to the extent that margin requirements are met
If the investor fails to put up additional cash, then the broker has the authority to sell securities for the investors account
Some brokerages set different margin limits by restricting which stocks can be margined
High volatility stocks like xoom.com or etoys (both now bankrupt) may not be marginable
Market Indicies: Market Indicies An index is based on a statistical aggregation of share prices in a number of representative securities. The index is a single price representation for a basket of stocks that can be tracked by investors how wish to understand aggregate market movement
Popular examples
Dow Jones 30
Nasdaq composite
NYSE Composite
Russell 1000
S&P 500
Wilshire 5000
Value line composite
Indices are fictitious constructs defined by whomever created the index
Standard & Poors created the S&P500
Dow Jones created the DJ30 or DJIA
Index pricing methods: Index pricing methods Indicies are priced by weighting
Value weighting – companies with higher market capitalization (Microsoft & IBM) are weighted more heavily
Price weighting: Each stock is weighted by the price, or in other words, equal number of shares are invested in each security (buy 100 shares of each firm).
Equal weighting: Each stock is equally weighted regardless of market value of price. Assumes that equal dollar amounts are invested in each security (buy $100 in each firm).
Most indices, like the SP500 are value weighted, but the DJIA is price weighted. Price weighting is problematic when stock splits occur, and because of this, the DJIA has to use an index divisor.
DJIA – (1/divisor) * (the sum of all 30 share prices)
the divisor is adjusted for stock splits.
as of 11/15/2004, the divisor was a nice round 0.13532775
criticism of DJIA is that higher priced stock has a higher impact on the average.
Price weighted index: Price weighted index If divisor is 2, then price weighted index (PWI) is:
Index = (40 + 100) / 2 = $70
After Split divisor becomes
$70 = (40 + 50)/divisor
divisor = 90/70 = 1.285
Index = (40 + 50)/ 1.285 = $70
With the new divisor, the index remains unchanged with the split. Example: How does a price weighted index treat a stock split?
Consider a two stock index:
Market Value weighted Index: Market Value weighted Index Market Value weighting is weights each index component in proportion to its market capitalization. Consider the S&P500 composition, and in particular, the top 10 holdings (2001 data)
GE = 3.4%
Exxon Mobil = 2.9%
Microsoft = 2.6%
Citigroup = 2.2%
Wal-mart=2.0%
Pfizer = 1.8%
B of A = 1.7%
Johnson & Johnson = 1.7%
AIG = 1.5%
IBM = 1.5%
The top 10 holdings represent 21% of the entire market capitalization of the index, but represents only 2% of the total firms – would be 2% if equal weighted.
Index correlation: Index correlation Indices are highly correlated – portfolios remove idiosyncratic risk, therefore different indices are simply comparing different measure of systematic risk in the market
DJIA is systematic risk in industrial firms
NASDAQ 100 measure the systematic risk in high tech
SP500 measures the systematic risk as a broader market measure.
Dow Jones 30 correlation with other indices:
74% with Nasdaq composite
95% with NYSE composite
93% with Russell 1000
95% with SP500
87% with value line
92% with Wilshire
