Lecture 2 Capital Markets, EMH & Valuation Investment Analysis

Valuation Myths Myth 1:Since valuation models are quantitative, valuation is objective. Myth 2:A good valuation provides a precise estimate of value. Myth 3:The more quantitative a model, the better the valuation. Myth 4:Once calculated, the value is full and final. Investment Analysis

Stock Market – Basics Capital Market – A market for intermediate or long-term debt or corporate stocks. Stock Market and Stock Exchange – A stock exchange is the most important component of a stock market. It is an organized and regulated financial market where securities (bonds, notes, shares) are bought and sold at prices governed by the forces of demand and supply. – To be able to trade, a security on a certain stock exchange, it has to be listed there. Trade on an exchange is by members only. Over-the-Counter (OTC) Market – There is usually no compulsion to issue stock via the stock exchange, such trading is said to be off exchange or over-the-counter. This is the usual way that bonds are traded. – The OTC market is a negotiated market in which investors negotiate directly with the dealers. In contrast, the registered exchanges are markets in which the broker acts as an intermediary between the buyer and seller. – The term “OTC” has changed in meaning over the years. OTC used to simply refer to any trading system that did not have a trading floor. However, the term OTC has changed to refer instead to those stocks that do not meet the listing requirements of any of the major exchanges. Investment Analysis

Stock Market – Basics Primary Market – A market where corporations raise new capital. Secondary Market – A market where existing or outstanding securities are traded among investors. Third Market – Stocks listed on a registered exchange may also be traded in the OTC market. Non- member investment firms can make markets in and trade registered securities without going through the exchange. This segment of the OTC market is called the third market. Fourth Market – The fourth market describes the direct exchange of securities between investors without using the services of a broker as an intermediary. Directly negotiated sales are done by investors to save transaction costs. Investment Analysis

Efficient Markets & Abnormal Returns We need to define what we mean by: Can we make money by trading stocks? One definition: We can make money = We can find a (riskless) arbitrage We adopt a broader definition: We can make money = We can achieve an expected return which is “large” relative to the risk. Investment Analysis

Market Efficiency Definition 1: A market is efficient if we cannot achieve significant abnormal returns. Definition 2: A market is efficient if price changes are not predictable. The two definitions are consistent: – If price changes were predictable, then we could achieve abnormal returns. Investment Analysis

Efficient Market Hypothesis (EMH) The EMH, developed by Eugene Fama in his influential paper published in 1960s, states that it is impossible to consistently outperform or beat the market by using any information that the market already knows, except through luck. According to the EMH, stocks always trade at their fair value on stock exchanges and thus its is impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices or in other words to consistently make abnormal returns. Investment Analysis

Three Forms of Market Efficiency Three forms of market efficiency are: – Weak form. – Semi-strong form. – Strong form. Investment Analysis

1.The Weak Form A market is weak-form efficient if we cannot achieve abnormal returns by using information contained in past prices. The conclusion is that an investor cannot achieve excess returns using technical analysis. Example: Weak-form efficiency implies that the following statement is incorrect: –Years when the market goes up are expected to be followed by years when it goes down. If a market is weak-form efficient, then technical analysis (the search for predictable patterns in prices) is futile. Investment Analysis

2. The Semi-Strong Form A market is semi-strong form efficient if we cannot achieve abnormal returns by using publicly available information. The conclusion is that an investor cannot achieve abnormal returns using fundamental analysis. Publicly available information consists of past prices, trading volume, company announcements, macroeconomic announcements, etc. Example: Semi-strong form efficiency implies that the following statement is incorrect: –After a dividend decrease, the price decreases but the decrease takes place gradually over several days. Investment Analysis

3. The Strong Form A market is strong-form efficient if we cannot achieve returns by using all publicly available and private information. Private information is information of a company’s insiders not yet available to all investors. As a base level knowledge of the EMH, we should know that: – Weak form addresses security market information; – The semi-strong form addresses security market and non-market public information; and the – Strong form addresses security market, non-market and inside or private information. Investment Analysis

Theoretical Reasons for Market Efficiency There are good theoretical reasons to expect markets to be weak and semi-strong form efficient: – There are many sophisticated investors. – These investors have access to publicly available information. – They can eliminate any abnormal returns. There is no good reason to expect markets to be strong- form efficient. – Sophisticated investors may not have access to private information. Investment Analysis

Principles of Valuation Time Value of Money Present Value Opportunity Cost of Capital Investment Analysis

Valuation Applications Real Assets (Capital Budgeting) Bonds (Financing Decisions) Stocks and Firms (Financing Decisions) Common Feature Invest cash today in exchange for expected, but generally risky, cash flows in the future. Time01234… CostCF 0... PayoffCF 1 CF 2 CF 3 CF 4 … Investment Analysis

Valuation (cont’d …) Asset CF 0 CF 2 CF What determines the value of the asset? What factors are important? Investment Analysis

Valuation (cont’d …) Time Value of Money $1 today is worth more than $1 in the future. Principle of the time value of money: – If receiving a fixed sum, want it as soon as possible. – If paying a fixed sum, delay payment for as long as possible. Investment Analysis

Valuation (cont’d …) Suppose CF t is riskless Time value of money A $1 received in the future is always worth less than $1 received today. If the interest rate is r, then the ‘present value’ of a riskless cash flow CF t received in t years is: CF t Present value = (1+r) t Investment Analysis

Valuation (cont’d …) Investment Analysis

Time Value of Money You have $1 today and the interest rate on risk free investments (Treasury bills) is 5% How much will you have in … 1 year …$1 x 1.05 = $ years …$1 x 1.05 x 1.05 = $1.103 t years …$1 x 1.05 x 1.05 x 1.05 = $1.05 t These cash flows are equivalent to each other. They all have the same value.  $1 today is equivalent to $(1+r) t in t years  $1 in t years is equivalent to $1(1+r) t today Investment Analysis

Example Your firm spends $800,000 annually for electricity at its Karachi headquarters. A sales representative from Khan Controls wants to sell you a new computer-controlled lightning system that will reduce electricity bills by roughly $90,000 in each of the next three years. If the system costs $230,000 fully installed, should you go ahead with the investment? Assume the cost savings are known with certainty and the interest rate is 4%. Investment Analysis
