Reading 13 - Technical Analysis Flashcards
What is Technical Analysis?
Technical analysis is a security analysis technique that involves the examination of past market trends (using data such as prices and trading volumes) to predict the future behavior of the overall market and of individual securities. It can be thought of as the study of collective investor sentiment. Technical analysis can be used in any global freely traded market (i.e., a market where buyers and sellers can trade without any external interference).
Technical analysis does not require an in depth knowledge of the security being analyzed, and can therefore be performed relatively quickly, while fundamental analysis usually takes longer. Further, technical analysis can be applied to identify short-term and long-term trends. Fundamental analysis is more time consuming so most investors with short time horizons focus on technical analysis.
Technical analysis is based on the following:
- Supply and demand determine prices in real time.
- Changes in supply and demand cause changes in prices.
- Prices can be projected with charts and other technical tools.
What are the principles and assumptions of technicians?
Fundamental analysts assert that markets are efficient and rational, but technicians believe that people often behave in an irrational and emotional manner, and tend to behave similarly in similar circumstances. Technicians suggest that market trends and patterns reflect irrational human behavior. Therefore, technicians study trends in the market, which they believe repeat themselves, to predict the future direction of security prices.
Technicians believe that the market reflects collective investor knowledge and sentiment. They rely on price and volume information from the market itself to understand investor sentiment and to make investment decisions.
While some financial instruments (e.g., stocks and bonds) have associated income streams (e.g., dividends and coupon payments), which can be used to determine their intrinsic values, others (including commodities and currencies) do not have underlying financial statements or associated income streams. Technical analysis is the only tool available to investors to forecast future prices for these asset classes.
Technicians believe that security price movements occur before fundamental developments occur or are reported. An important tenet of technical analysis is that the equity market moves roughly six months ahead of crucial turning points in the broader economy.
Technical vs. Fundamental Analysis
Technical analysis uses only trading data, which includes market price and volume information. Fundamental analysis uses external information (e.g., financial reports, industry and macroeconomic analysis) and also incorporates social and political variables.
The data used by technical analysts is more concrete and reliable. The financial statements used by fundamental analysts are subject to manipulation by management.
Fundamental analysis is more conceptual as it aims to determine the theoretical long‐term (intrinsic) value of a security. Technical analysis is more practical as it studies actual trading patterns to evaluate the market price of a security. Stated differently, fundamental analysts aim to forecast where a security should trade, while technicians focus on predicting the level at which it will trade.
Technical analysis has been in use for a longer period in investment decision‐making. Fundamental analysis is a relatively new field.
Drawbacks of Technical Analysis
Technicians only study market movements and trends, which can change without warning. Further, it may take some time for a clear, identifiable trend to emerge. Technicians can therefore make incorrect investing decisions and can be late in identifying changes in trends.
Fundamental analysts demand an understanding of factors that will drive a company’s performance going forward. Technicians expect trends to repeat themselves so a change in investor psychology may be missed by them.
Application of technical analysis is limited in markets that are subject to significant outside manipulation (markets that are not freely traded) and in illiquid markets (where even a modest trade may have a relatively significant price impact).
What are the primary tools in technical analysis?
Charts and indicators are the primary tools used in technical analysis.
Technical Analysis: Charts
Charts are used to illustrate historical price information, which is used by technicians to infer future price behavior. A wide variety of charts are used in technical analysis. The choice of charts is governed by the purpose of the analysis.
Technical Analysis: Line Charts
A line chart (see Figure 2-1) is a simple graphical display of prices over time. Usually the chart plots closing prices as data points, and has a line connecting these points. Time is plotted on the horizontal axis and prices are plotted on the vertical axis. Line charts provide a broad overview of investor sentiment, and the information they provide can be analyzed quickly.

Technical Analysis: Bar Charts
While a line chart has one data point for each value of the horizontal axis (time), a bar chart presents four pieces of information—opening price, highest and lowest prices, and the closing price for each time interval (see Figure 2-2). Bar charts enable an analyst to get a better sense of the nature of trading during the period. A short bar indicates low price volatility, while a longer bar indicates high price volatility.
For each time interval, the top of the line shows the highest price, while the bottom of the line shows the lowest price. The cross‐hatch to the left indicates the opening price, while the cross‐hatch to the right indicates the closing price. (See Figure 2-3.)

Candlestick Charts
A candlestick chart provides the same information as a bar chart (i.e., opening and closing prices, and highs and lows during the period). Further, it also clearly illustrates whether the market closed up or down. The body of the candle is shaded if the closing price was lower than the opening price, and the body is clear if the closing price was higher than the opening price. (See Figures 2-4 and 2-5.)

Technical Analysis: Doji
No difference between high and low. Further, the shares opened and closed at the same price; hence the cross pattern. Such a pattern is known as a doji. A doji indicates that the market is in balance. If it occurs after a strong uptrend or downtrend, it suggests that the trend is about to reverse.
Technical Analysis: Point and Figure Chart
To construct a point and figure chart, a box size and a reversal size must first be determined. The box size refers to the minimum change in price that will be represented by a box on the chart, while the reversal size determines when a new column will be created on the chart. The reversal size is typically a multiple of the box size. A reversal size of three means that an analyst will move to the next column when the price reverses, or changes direction by three or more boxes. The vertical axis measures discrete movements in price.
To construct the chart, an “X” is plotted for an increase in price, while an “O” is plotted for a decrease in price. For example, assume that the box size is $1 and the reversal size is $3. If the price rises by $1 on the first day, the analyst puts an X. On the next day, if the price increases by $2 the analyst plots 2 further Xs on top of the X already plotted. On the third day, if the price rises by $0.50, nothing is plotted on the chart (as the price change is lower than the box size). The analyst will continue to mark Xs in the same column whenever the price increases by more than $1 on a given trading day until a reversal occurs. A reversal would occur in this case when the price falls by $3 or more. When a reversal occurs the analyst would move over to the next column and start marking Os. The first box to be filled with an O would be the one to the right and below the highest X in the previous column. (See Figure 2-6.)
Box and figure charts are useful as they highlight the prices at which trends change (when the columns change), as well as price levels at which the security most frequently trades (congestion areas). Long, sustained price movements are represented by long columns of Xs and Os.
In Technical Analysis, point and figure charts, what is the point of having a multi-box reversal size?
The point of having a multi‐box reversal size is to ignore the short‐term price volatility or noise that does not alter the long‐term price trend.
Technical Analysis: Scale
The vertical axis on any of the charts that we have already discussed can be constructed with a linear (arithmetic) scale or a logarithmic scale. A linear scale is more appropriate when the data fluctuate within a narrow range (see Figure 2-7). In a logarithmic scale, percentage changes are plotted on the vertical axis. They are more appropriate when the range of data is larger (see Figure 2-8). Time is plotted on the horizontal axis. The length of the time period depends on the underlying data and the purpose of the chart. Active traders typically prefer shorter time intervals.

Technical Analysis: Volume
Volume is used by technicians as a barometer of the strength of a trend. Volume‐related information is typically included at the bottom of most charts (see Figure 2-9).
If a security’s price is increasing with increasing volumes, it shows that more and more investors are purchasing the stock at higher prices. This indicates that the trend is expected to continue as the two indicators “confirm” each other.
If a security’s price is rising with declining volumes (the two indicators are diverging), it suggests that the trend is losing momentum as fewer investors are willing to buy at higher prices.

Technical Analysis: Time Intervals
Charts can be constructed using any time interval. The decision regarding which interval to use varies across the nature of trading—short-term investors may create charts with intervals less than a minute long, while longer-term investors may use charts with intervals as long as one year.
