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: Line chart example (explain)
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.)

Technical Analysis: Bar Chart Example (Explain)
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.
Technical Analysis: Relative Strength Analysis
Relative strength analysis is used to evaluate the relative performance of a security compared to a stated benchmark by plotting the ratio of the security’s price to the benchmark index over time. An upward‐sloping line indicates outperformance, while a downward‐sloping line suggests underperformance. (See Figure 2-10.)

Technical Analysis: Trend analysis
Trend analysis assumes that investors tend to behave in herds and that trends usually continue for an extended period of time. Stock price data may show an uptrend, a downtrend, a sideways trend, or in some cases no trend at all.
Technical Analysis: Uptrend
An uptrend occurs when a security’s price makes higher highs and higher lows. Higher highs occur when each high lies above the previous high, and when the price declines (there is a retracement) each subsequent low is higher than the prior low. To illustrate an uptrend, the technician connects all the lows on the price chart with a straight line. Major retracements (that drag the security’s price significantly below the trend line) indicate that the uptrend is over and that the price may decline further.
In terms of demand and supply, during an uptrend, there are more ready buyers for a security than there are sellers and traders are willing to pay a higher price for the security over time.
Technical Analysis: Downtrend
A downtrend is indicated by lower highs and lower lows on the price chart. A technician connects all the highs on the chart to illustrate the downtrend. Major breakouts above the trend line may indicate that the downtrend is over and that the security’s price could rise further.
In a downtrend, sellers are willing to accept lower and lower prices for the security, which indicates negative investor sentiment regarding the asset. (See Figure 2-11.)
Technical Analysis: Sideways trend
In some cases, a security may trade within a narrow range. During such a sideways trend, there is a relative balance between demand and supply. Typically, options positions are more profitable than long or short positions on the security itself during a sideways trend.
Technical Analysis: Trend analysis graph (Explain)
Technical analysis: Support and resistance levels
Trend analysis involves the use of support and resistance levels. A support level is defined as the price at which there is sufficient buying interest in the stock to arrest the price decline. At this level, investors believe that the security is an attractive investment despite the recent price decline. (See Figure 2-12.) On the other hand, a resistance level is the price at which enough selling activity is generated to prevent any further increase in price. At the resistance level, investors believe that the security is overpriced. Support and resistance levels may be horizontal or sloped lines.
The psychology behind the concepts of support and resistance is that investors have come to a collective consensus about the price of a security.
Technical analysis: Change in polarity principle
The change in polarity principle (a key tenet of trend analysis) asserts that once the price rises above the resistance level, it becomes the new support level. Similarly, once the price falls below a support level, it becomes the new resistance level.

Technical Analysis: Chart patterns
Chart patterns are formations on price charts that look like recognizable shapes. Recurring chart patterns can be used to predict future prices because these patterns essentially represent collective investor sentiment over a given time period. Chart patterns may be categorized as reversal patterns or continuation patterns.
Technical Analysis: Reversal patterns
As the name suggests, reversal patterns indicate the end of a prevailing trend.
Technical Analysis: Head and Shoulders. A head and shoulders pattern, see Figure 2-13, follows an uptrend in the price of a security. It is composed of three parts:
Left shoulder
Head
Right Shoulder
Technical Analysis: Head and Shoulders. Left Shoulder:
Left shoulder: The left shoulder consists of a strong rally with high volumes, with an upward trend that has a slope that is steeper than that of the preceding uptrend. The rally then reverts to the same price that it started from, creating an inverted “V.”
Technical Analysis: Head and Shoulders. Head:
Head: The price starts to rise again, and this time records a higher high than the one reached in the left shoulder. However, volumes in this rally are lower. The price then again falls to the level that the head started from (the same level at which the left shoulder began and ended). This price level is called the neckline.
Technical Analysis: Head and Shoulders. Right Shoulder:
Right shoulder: The right shoulder is similar to the left shoulder, but with lower volumes. The price rises almost to the same level as the high of the “left shoulder,” but remains lower than the high reached during the “head.”
Technical Analysis: Head and Shoulders. Point on formation on the price chart
While the formation on the price chart may not always be perfect, the head should clearly be above the two shoulders, both of which should be similar. Note that the neckline may not always be a perfectly horizontal line.
Technical Analysis: Head and Shoulders. Note on volume
Volume is very important in analyzing head and shoulders patterns. The fact that the high of the “head” is higher than the “high” of the left shoulder, but has lower volumes, indicates that investor interest is waning. When one indicator is bullish (rising price) while another is bearish (lower volumes) it is known as a divergence.
Technical Analysis: Head and Shoulders. Note on volume
Volume is very important in analyzing head and shoulders patterns. The fact that the high of the “head” is higher than the “high” of the left shoulder, but has lower volumes, indicates that investor interest is waning. When one indicator is bullish (rising price) while another is bearish (lower volumes) it is known as a divergence.
Technical Analysis: Head and Shoulders. Filtering rules
Once a head and shoulders pattern has formed, prices are expected to decline (the uptrend that preceded the head and shoulders pattern is expected to reverse). Technicians use filtering rules to ensure that the neckline has been breached. An example of such a filter is the price declining to a level 3–5% below the neckline. Once the price falls below the neckline (which previously acted as a support level), it becomes the new resistance level (change in polarity principle).
Technical analysis: head and shoulders: Graph
Technical analysis: Inverse Head and Shoulders
A downtrend in prices precedes an inverse head and shoulders pattern. The price characteristics of each of the three segments of the head and shoulders pattern are reversed in an inverse head and shoulders pattern, but the volume characteristics are the same. For example, in the left shoulder, the slope of the price decline is greater (more negative) than that of the preceding downtrend, but volumes are heavier. Then the rally reverses (with lower volumes) toward where it originated, and forms a “V.”
Technical analysis: Setting Price Targets with head and shoulders patterns
Once the neckline has been breached in the head and shoulders pattern, the price is expected to decline by an amount equal to the distance between the top of the head and the neckline. An investor can benefit from this expected reversal by shorting the security once the price falls below the neckline and then repurchasing it (closing the position) at the (lower) target price. As shown in Figure 2-14, the price target is calculated as:
Price target = Neckline + (Head - Neckline)
Typically, the stronger the rally preceding the head and shoulders pattern, the more pronounced the expected reversal.
Technical analysis: Calculating price target (Graph)
Technical analysis: Setting price targets for inverse head and shoulders pattern
Inverse head and shoulders patterns are preceded by a downtrend. Therefore, prices are expected to rise or break out above the neckline after the right shoulder has been formed. (See Figure 2-15.)
Price target = Neckline + (Neckline – Head)

Technical analysis: double tops and bottoms
A double top occurs when an uptrend in prices reverses twice at approximately the same price level (two highs are recorded at roughly the same level). Usually, the first top has a higher volume.
For a double top, the price target (where the reversal will end) is established at a level that is lower than the valley (the low recorded between the two tops) by an amount that equals the distance between the tops and the valley.
The more significant the sell‐off after the first top (deeper the valley) and the longer the time period between the two tops, the more significant the formation is considered to be.
A double bottom indicates the reversal of a downtrend. It occurs when, following a recent downtrend, prices fall to a certain level, rise for a bit, then fall back to the same level and rise again. (See Figure 2-16.)
For double bottoms, the price is expected to rise above the peak between the two bottoms by approximately an amount equal to the distance between the bottoms and the peak.
Technical analysis: Double-Bottom Pattern (Graph)
Technical analysis: why are double tops and bottoms significant?
Double tops and bottoms are significant because they indicate that at a particular price level, investors are ready to step up and reverse the prevailing trend. For example, with a double bottom, the suggestion is that price declines have been arrested at a similar level on two different occasions, indicating that market consensus is that the price is low enough for the security to be an attractive investment.
Technical analysis: Triple tops and bottoms
A triple top consists of three peaks at roughly the same level (see Figure 2-17), while a triple bottom occurs when three troughs are formed at roughly the same price level. Triple tops and bottoms are rare, but when they occur, they indicate more significant reversals than double tops and double bottoms. Generally speaking, the greater the number of times the price reverses at a given price level, and the longer the period over which the pattern is formed, the more significant the expected reversal.
Technical analysis: Triple tops and bottoms (Graphs)
Technical Analysis: Continuation Patters
A continuation pattern is used to confirm the resumption of the current market trend. Also known as “healthy market corrections,” these patterns suggest that the current price trend will continue as ownership of securities changes from one group of investors to another. In an uptrend for example, while one group of investors is looking to exit, another stands ready to take a long position on the asset at approximately the same price level.
Technical Analysis: Triangle Patterns
A triangle pattern is formed when the range between highs and lows over a period narrows down on the price chart. The line connecting the highs over the period eventually meets the line connecting the lows, forming a triangle.
