FNCE 3020Financial Markets and Institutions Lecture 6; Part 2 Forecasting with Fundamental Analysis and Technical Analysis
Beginning Quotes • “If past history was all there was to the game, the richest people would be librarians.” • Warren Buffett • “Markets can remain irrational longer than you can remain solvent.” • John Maynard Keynes
Objective for This Lecture Series To introduce you to two very different approaches to forecasting financial asset prices. Fundamental analysis Uses economic and financial data upon which to base the calculation of the appropriate price of a financial asset. Tries to identify undervalued assets. Technical analysis Forecasting of future financial price movements based on an examination of past price (and volume) movements.
Forecasting Assuming Efficient Markets • According to the Efficient Market Hypothesis, when new information hits the market, the news spreads very quickly and is incorporated into asset prices without delay. • If this this the case, then any technique promising greater returns than the over-all market itself is questionable at best. • So as we work through the following two forecasting approaches, we need to consider how efficient markets would impact upon each technique.
Fundamental Analysis • This technique attempts to identify “undervalued” financial assets, so that if purchased would enable the investor to achieve returns greater than those that could be obtained by holding a portfolio of the financial assets in question. • But, if markets are efficient, financial assets are priced correctly, i.e., there will be no undervalued assets.
Fundamental Analysis: Selecting Appropriate Model • The selection of an appropriate “pricing” model is critical to the forecast for a particular financial asset. • Long-term Bonds • Interest rate models with focus on future inflation. • Foreign Exchange (short term horizon) • Short term interest rate differential models with focus on central bank policies • Foreign Exchange (longer term horizon) • Trade (imports and exports) and capital flows (stock market, foreign direct investment). • Inflation. • Common stock • Economic, industry and company models.
Fundamental Analysis: Common Stock • Historically this is the approach most used by financial analyst. • Popularized by Columbia University Professors Benjamin Graham and David Dodd (1934, Security Analysis). • They argued that investors should buy stocks in corporations that have undervalued assets relative to their true market value, or • current assets exceeding current liabilities, • low price/earnings ratio. • Graham and Dodd advocated searching out stocks which are undervalued by the market. • Once an undervalued security is found, it's simply a matter of buying the stock and waiting for the market to realize the "more accurate" value of that security.
Fundamental Analysis: Common Stock • Fundamental approach has used successfully by Warren Buffett who actually studied under Benjamin Graham at Columbia University in the early 1950s. • After graduation Buffett applied for a job with Graham investment firm, but was initially turned down! • In April 3, 1995, Warren Buffett was quoted (Fortune Magazine) as follows “I'd be a bum in the street with a tin cup if the markets were efficient.“ • For an interesting account of Warren Buffett see: • http://beginnersinvest.about.com/cs/warrenbuffett/a/aawarrenbio.htm
Calculating the Value of Common Stock • There are two general approaches to valuing common equity: 1) the discounted cash flows approach, and 2) the relative valuation approach. • Discounted Cash Flow: A stock’s value is based on the present value of its future cash flows, such as dividends. • Relative Valuation Approach: Values a stock based on its current price relative to certain variables, such as the company's earnings, revenues or book value.
Top Down Fundamental Approach • This approach is probably the most comprehensive of all fundamental techniques. It can involve specific steps such as: • 1. Economic Forecast (global, national, regional) • 2. Group (Industry) Selection • Which industries are likely to do well in the forecasted environment. • 3. Analysis of Companies within the Group • Leaders, innovators, start-ups, etc. • 4. Company Selection • Company’s Plans and Outlook • New product development, red flags (litigation, etc.) • Management • Financial Analysis
Technical Analysis • This technique examines past financial asset prices in an attempt to predict future asset prices. • However, if markets are efficient, then the quick flow of information will be immediately reflected in asset prices and tomorrow's price change will reflect only tomorrow’s news. • But, according to the efficient market hypothesis, tomorrow’s news is unpredictable and thus tomorrow’s price changes will be unpredictable and random.
Technical Analysis • History: Its origins can be traced to articles published by Charles H. Dow in the Wall Street Journal between 1900 and 1902. • Dow suggested the use of “past price behavior to guide investing decisions.” • Technique became popular after contributions by Hamilton (1922) and Rhea (1932). • Technical analysis believes that the price of an asset is determined by supply and demand. • Simply put, technical analysis uses charts which indicate the beginning of shifts in demand and/or supply – and thus lead price changes. • Recall, technical analysis is at odds with the random walk assumption of the Efficient Market Hypothesis.
Definitions of Technical Analysis Robert Edwards and John Magee’s classic book (Technical Analysis of Stock Trends, 1948): Technical Analysis is the science of recording, usually in graphic form, the actual history of trading (price changes, volume of transactions, etc.) in a certain stock or in “the Averages” and then deducing from that pictured history the probable future trend.” Martin J. Pring (Technical Analysis Explained, 1979). "The technical approach to investing is essentially a reflection of the idea that prices move in trends which are determined by the changing attitudes of investors toward a variety of economic, monetary, political, and psychological forces. The art of technical analysis -- for it is an art -- is to identify trend changes at an early stage and to maintain an investment posture until the weight of the evidence indicates that the trend has reversed."
Technical Analysis: Summary Technical Analysis This approach is NOT interested in financial or economic data that may affect the asset’s price. Sometimes referred to as “noise” trading (i.e., not interested in news). Utilizes charts of past price movements to estimate where prices may move in the future. Sometimes referred to as a chartist (or charting) approach. Assumes prices are not random That patterns of prices develop and can be used to forecast the future. Generally uses a short time frame: intraday (1-minute, 5-minutes, 10-minutes, 15-minutes, 30-minutes or hourly), daily, weekly or monthly. Can be applied to any financial asset who’s price is determined by supply and demand. Stock, bonds, foreign exchange, key commodities.
Examples of Technical Approaches Moving Average Analysis of Stocks Where is the individual stock (or market) in relation to some moving average of past prices? If breaking above moving average, this is a signal of strength. If breaking below moving average, this is a signal of weakness. Overbought and Oversold Analysis of Stocks Is the individual stock (or market) trading above or below its historical range? Above its range suggests overbought condition. A signal that the stock (or market) should move down. Below its range suggests oversold condition. A signal that the stock (or market) should move up. Head and Shoulders Reversal Pattern of Stocks Specific price and volume pattern which signals a reversal of the prior trend.
Head and Shoulders Patterns • Head and shoulders is a reversal pattern that, when formed, signals the security is likely to move against its previous trend. • The signal appears to be most reliable (?) in detecting a reversal of an uptrend. • A Head and Shoulders pattern consists of four distinct parts: The left shoulder, the head, the right shoulder, and the neckline. Each of these four must be present for the formation to exist. • In addition, the volume pattern must also meet strict requirements. Volume must show a peak on the left shoulder, a lower peak at the head, and then an even lower level at the right shoulder.
Head and Shoulder Formation Left Shoulder: A high volume rally and top followed by a minor reaction with significantly less volume than during the rise and top. Head: Another high volume rally with the top reaching a higher level than the left shoulder, followed by a another reaction on less volume that takes the price to a level near the bottom of the previous reaction. Right Shoulder: A third rally on noticeably less volume that fails to reach the top of the head. Neckline: A decline in prices from the top of the right shoulder which falls below the line formed when connecting the bottoms of the left shoulder and head by at least 2-3% of the stock's market value. Head and Shoulders as a Reversal Pattern in an Uptrend
Use of Technical Analysis in Foreign Exchange Markets • During the last 15 years or so – beginning with joint research by Mark P. Taylor and Helen Allen (1990, 1992) – a number of studies have reported the results of surveys of foreign exchange market participants in the major trading centers concerning the use of technical analysis. • These studies concluded that technical analysis is in widespread use among foreign exchange professionals. • As early examples see: • Allen, Helen, and Mark P. Taylor. 1990. "Charts, Noise and Fundamentals in the London Foreign Exchange Market." Economic Journal 100 (supplement): 49-59. • Taylor, Mark P., and Helen Allen. 1992. "The Use of Technical Analysis in the Foreign Exchange Market." Journal of International Money and Finance 11: 304-14.

Appendix 1 Interview with Benjamin Graham
Interview with Graham in the 1970s Question: In selecting the common stock portfolio, do you advise careful study of and selectivity among different issues? Graham: In general, no. I am no longer an advocate of elaborate techniques of security analysis in order to find superior value opportunities. This was a rewarding activity, say, 40 years ago, when our textbook “Graham and Dodd” was first published; but the situation has changed a great deal since then. In the old days any well-trained security analyst could do a good professional job of selecting undervalued issues through detailed studies; but in the light of the enormous amount of research now being carried on, I doubt whether in most cases such extensive efforts will generate sufficiently superior selections to justify their cost. To that very limited extent I’m on the side of the “efficient market” school of thought now generally accepted by the professors.
Appendix 2: Three Forms of Market Efficiency and Forecasting The following two slides discuss (1) the three forms of market efficiency and (2) the use of forecasting with these three forms.
Three Forms of The Efficient Market Hypothesis There are actually three stages of the EMH model: Weak Form: Current prices reflect all past price and past volume information. The fundamental information contained in the past sequence of prices of a security is fully reflected in the current market price of that security. Semi-strong Form: Current prices reflect all past price and past volume information AND all publicly available information. Information such as interest rates, earnings, inflation, etc. Strong Form: Current prices reflect all past price and past volume information, all publicly available information publicly available information AND all private (e.g., insider) information.
Forecasting asset prices within the 3 Types of Efficient Markets: Weak form: In this type of a market, all past data and prices are reflected in the current prices. Thus, Technical Analysis is not of any use. Semi strong form: In this type of a market, all public information is reflected in the current stock prices. Thus, here, even Fundamental Analysis is of no use (as well as technical analysis) Strong form: In this type of market, all information is reflected in the current stock prices. Thus, not only is any kind of analysis useless, even insider information is useless for predicting future stock market prices.
