10.7 Technical Analysis: Charts, Trends & Patterns

Fundamental vs. Technical Analysis: The Foundational Philosophy

While fundamental analysis seeks to establish a security's intrinsic value based on economic, industry, and financial statement data (determining what security to buy), technical analysis evaluates the market's price action, volume dynamics, and sentiment to identify optimal market timing (determining when to buy or sell).

Core Tenets of Technical Analysis
 ├── 1. The Market Action Discounts Everything
 │    └── All public and private information, earnings, economic data, and investor emotions are reflected in price
 ├── 2. Prices Move in Trends
 │    └── Once established, a trend is more likely to continue than to reverse randomly
 └── 3. History Repeats Itself
      └── Human psychology produces recurring, identifiable chart patterns across all timeframes

The Three Core Assumptions of Technical Analysis

1. The Market Discounts Everything: Technical analysts believe that all relevant macroeconomic variables, corporate financial statements, competitive advantages, future expectations, and human emotions (fear and greed) are instantaneously synthesized and reflected in the market price. Therefore, analyzing financial statements is seen as redundant because current supply and demand already reflect all known information.
2. Prices Move in Trends: Asset prices do not wander randomly; instead, they move in identifiable trends (upward, downward, or sideways) that persist over time. The primary objective of technical analysis is to identify a trend in its early stages and participate in that trend until definitive technical evidence indicates a reversal.
3. History Tends to Repeat Itself: Human emotional responses to market gains and losses are consistent across generations. This collective investor psychology produces recurring, recognizable chart geometries (such as support floors, resistance ceilings, and head and shoulders formations) that signal the continuation or exhaustion of market trends.

Principles of Dow Theory

Formulated by Charles Dow, the foundational principles of modern technical analysis include:

• The Averages Discount Everything: Stock market averages (such as the S&P/TSX Composite or Dow Jones Industrial Average) reflect the collective knowledge and sentiment of all market participants.
• The Market Exhibits Three Trends:
  • Primary Trend: The overarching multi-year trend (bull or bear market) lasting from one to several years.
  • Secondary Trend: Intermediate counter-trend corrections or retracements lasting from three weeks to three months, retracing one-third to two-thirds of the primary move.
  • Minor Trend: Short-term day-to-day fluctuations lasting less than three weeks (often considered market noise).
• Volume Must Confirm the Trend: Trading volume should expand in the direction of the primary trend. In a healthy bull market, volume increases on rallies and contracts on corrective pullbacks.
• A Trend Remains in Effect Until Definite Reversal Signals Occur: A prevailing trend is assumed to continue until an authoritative reversal signal is confirmed.

Charting Techniques: Visualizing Market Action

Technical analysts display historical market data using three primary charting styles:

1. Line Charts

Line charts connect successive closing prices over time with a continuous line. They provide a clear view of long-term primary trends, filtering out intraday volatility. However, they omit the intraday price range (highs, lows, and opens).

2. Bar Charts (OHLC Charts)

Open-High-Low-Close (OHLC) bar charts display four distinct data points for each trading period:

• A vertical line connects the High and the Low of the period, displaying total volatility.
• A small horizontal tick on the left side indicates the Opening price.
• A small horizontal tick on the right side indicates the Closing price.

3. Candlestick Charts

Developed in 18th-century Japan by rice merchant Munehisa Homma, candlestick charts display the identical four data points (OHLC) as bar charts but format them to highlight the relationship between the open and close.

              Lower Shadow (Tail)                     Lower Shadow (Tail)

• Real Body: The wide central rectangle represents the range between the Opening price and the Closing price.
  • Bullish Candle (White or Green): The close is higher than the open, indicating that buyers controlled the session.
  • Bearish Candle (Black or Red): The close is lower than the open, indicating that sellers dominated the session.
• Shadows (Wicks and Tails): The thin vertical lines extending above and below the real body represent the session's intraday High and Low extremes.
• Common Candlestick Formations:
  • Doji: The opening and closing prices are identical (or nearly identical), forming a cross or plus sign. Indicates a balance between buyers and sellers and potential market indecision.
  • Hammer: A small real body at the top of the trading range with a long lower shadow (at least twice the height of the real body) appearing after a downtrend. Signifies that aggressive intraday selling was rejected by strong buying demand before the close, suggesting a bullish reversal.
  • Shooting Star: A small real body at the bottom of the range with a long upper shadow appearing after an uptrend. Reflects an intraday advance that was reversed by sellers, signaling a bearish reversal.
  • Engulfing Patterns: A two-candle reversal formation where the real body of the second day completely overlaps (engulfs) the real body of the preceding day.

Trend Analysis, Support, Resistance, and Role Reversal

Defining Trends

Prices move in three general directions:

• Uptrend: Characterized by a sequence of higher highs (peaks) and higher lows (troughs). An uptrend line is drawn by connecting at least two rising reaction lows (troughs) below the price action. It serves as dynamic support.
• Downtrend: Characterized by a sequence of lower highs and lower lows. A downtrend line is drawn by connecting at least two descending reaction highs (peaks) above the price action. It serves as dynamic resistance.
• Sideways / Horizontal Channel: Occurs when price oscillates between parallel horizontal support and resistance boundaries, reflecting balance between buyers and sellers.

Trend Geometries
  Uptrend (Higher Highs & Lows)           Downtrend (Lower Highs & Lows)
             ▲  Higher High                         Peak
            / \      ▲                             ▲ \  Lower High

      /                    \                 /

Support and Resistance Mechanics

• Support: A price level or zone where buying interest is strong enough to halt or reverse a downward price move. At support, demand overcomes supply, creating a "price floor."
• Resistance: A price level or zone where selling pressure is strong enough to halt or reverse an upward advance. At resistance, supply overcomes demand, creating a "price ceiling."
• Psychological Numbers: Support and resistance frequently cluster around psychologically significant round milestones (e.g., TSX 25,000, $50, $100 per share).

The Principle of Role Reversal

A central axiom of technical analysis is that once a support or resistance level is decisively breached, its functional role reverses:

The Principle of Role Reversal

   ▲                                            Breakout Rally
   │                                               /\
   │            Resistance Ceiling                /  \
───┼───────────▲─────────────────▲───────────────/────\───────► Former Resistance
   │          / \               / \  Breakout   /      \        Becomes NEW SUPPORT
   │         /   \             /   \   ▲       /        ▼ Pullback Re-test
   │        /     \           /     \ / \     /          (Strong Buy Zone)
   │       /       ▼         /       ▼   \   /
───┼──────▲─────────────────▲─────────────\─/─────────────────► Support Level
   │     /   Support Floor /               ▼
   └────┴─────────────────┴───────────────────────────────────► Time

• Former Resistance Becomes New Support: When price decisively breaks above a major resistance ceiling on expanding volume, that level becomes a support floor during subsequent pullbacks. Traders who sold at resistance regret their exit and look to buy when price returns to their breakeven level, while sidelined investors view the pullback as a second chance to enter.
• Former Support Becomes New Resistance: When price decisively breaks below a major support floor, that level becomes a resistance ceiling on subsequent counter-trend rallies. Investors who bought at support are trapped with paper losses and seek to sell at breakeven during any relief bounce, generating supply.

Major Chart Patterns: Reversal vs. Continuation

Chart patterns represent geometric formations created by historical price action. They are classified into reversal patterns (signaling a change in trend direction) and continuation patterns (signaling a temporary pause before the prevailing trend resumes).

1. Classic Reversal Patterns

The Head and Shoulders Top

The Head and Shoulders top is a reliable bearish reversal pattern that forms after an uptrend.

Head and Shoulders Top Reversal Pattern
                    Head (Peak)
                        ▲
                       / \
   Left Shoulder      /   \      Right Shoulder
         ▲           /     \           ▲
        / \         /       \         / \
       /   \       /         \       /   \    Breakdown
      /     ▼     /           ▼     /     ▼      ▲
─────┼───────▲───┼─────────────▲───┼───────▲─────┼───────► NECKLINE
     │        \ /               \ /         \   / 
     │         ▼                 ▼           \ /  Pullback Test
     │    Trough 1            Trough 2        ▼
     │                                    Downside Target Projected

• Anatomy:
  • Left Shoulder: A strong rally on heavy volume, followed by a minor pullback to an intermediate low.
  • Head: A second rally that penetrates above the left shoulder to reach a higher high, typically accompanied by moderate or declining volume, followed by a pullback to a similar low.
  • Right Shoulder: A third rally that fails to reach the peak of the head (forming a lower high), accompanied by noticeably lighter volume.
  • Neckline: A trendline drawn connecting the two intermediate reaction lows (Trough 1 and Trough 2).
• Breakdown Confirmation: The pattern is confirmed only when the closing price decisively breaks below the neckline on expanding volume.
• Price Target Calculation: $\text{Pattern Height} = \text{Price of Head} - \text{Price of Neckline}$ $\text{Minimum Downside Target} = \text{Neckline Breakdown Price} - \text{Pattern Height}$

Worked Example: A Canadian mining stock completes a Head and Shoulders top. The head peaks at $72.00, and the neckline sits at $58.00.

• Pattern Height: $72.00 - $58.00 = $14.00.
• Downside Target: $58.00 - $14.00 = $44.00. Technical analysts project a minimum price objective of $44.00.

Inverse Head and Shoulders (Bottom)

A bullish reversal formation occurring after a downtrend. Consists of a left shoulder trough, a lower head trough, and a higher right shoulder trough. A breakout above the upward neckline confirms the reversal, projecting an upside target of Neckline + Pattern Height.

Double Tops and Double Bottoms

• Double Top ("M" Formation): A bearish reversal pattern where price tests a resistance ceiling twice with an intermediate reaction low between the peaks. A confirmed breakdown below the intermediate low triggers a downside target equal to the vertical distance between the peak and the trough.
• Double Bottom ("W" Formation): A bullish reversal pattern where price tests a support floor twice without breaking lower. A breakout above the central intervening peak confirms the reversal, projecting an upside target equal to the pattern's vertical amplitude.

2. Continuation Patterns

Continuation patterns indicate that the market is consolidating before resuming its prevailing primary trend.

• Triangles:
  • Symmetrical Triangle: Formed by two converging trendlines (lower highs and higher lows), reflecting balanced consolidation. Usually breaks out in the direction of the prior trend.
  • Ascending Triangle: Formed by a flat, horizontal upper resistance ceiling and a rising lower support line. Indicates that buyers are becoming more aggressive; carries a strong bullish continuation bias.
  • Descending Triangle: Formed by a flat, horizontal lower support floor and a declining upper resistance line. Demonstrates persistent selling pressure; carries a bearish continuation bias.
• Flags and Pennants:
  • Short-term continuation patterns that form after a sharp, near-vertical advance or decline (known as the flagpole).
  • Flag: A compact, parallel rectangular price channel that slopes gently against the prevailing trend.
  • Pennant: A small, short-term symmetrical triangle with converging trendlines.
  • Price Target: Projects a "measured move" where the vertical length of the flagpole is added to the subsequent breakout point.
