Composite Chart

1. Composite Chart

A Composite Chart in technical analysis is a charting technique that combines multiple price series into a single chart, allowing traders to visualize relationships and potential trading opportunities that might not be immediately apparent when viewing each price series individually. This technique is particularly useful for analyzing correlated assets, identifying divergences, and confirming trends. It's a relatively advanced charting technique, but understanding the fundamentals makes it a powerful tool in a trader’s arsenal. This article will delve into the intricacies of composite charts, covering their construction, interpretation, applications, advantages, disadvantages, and practical examples.

What is a Composite Chart?

At its core, a composite chart is created by mathematically combining two or more price series. The most common application involves combining the price of a security (like a stock or commodity) with its inverse or a related security. This allows traders to see a unified representation of both bullish and bearish forces, or the interplay between different markets. It’s not simply overlaying charts; it’s a mathematical synthesis.

The idea behind creating a composite chart dates back to the work of Dr. Norman Kolb, who popularized the concept in the 1960s. Kolb's original work focused on combining the price of a stock with a broad market index, like the Dow Jones Industrial Average, to gauge a stock's relative performance. However, the technique has expanded to encompass various applications, including combining different timeframes, different assets within the same sector, and even combining different types of technical indicators.

Construction of a Composite Chart

The basic formula for constructing a composite chart is:

Composite Price = Price Series 1 + (Constant - Price Series 2)

Where:

• Price Series 1 is the price of the primary security you're interested in.
• Price Series 2 is the price of the inverse or related security.
• Constant is a numerical value used to scale the chart. This constant is generally set to the sum of the highest price of both price series, ensuring that the composite chart remains positive and provides a clear visual representation. Choosing the right constant is crucial for proper interpretation.

Let's break down an example:

Imagine you want to create a composite chart using Apple (AAPL) and the SPDR S&P 500 ETF Trust (SPY).

1. **Identify Price Series:**

   *   Price Series 1: AAPL Price
   *   Price Series 2: SPY Price

2. **Determine the Constant:** Find the highest price reached by both AAPL and SPY over the period you're analyzing. Let's say AAPL peaked at $198 and SPY peaked at $500. The constant would be 198 + 500 = 698.

3. **Calculate the Composite Price:**

   *   Composite Price = AAPL Price + (698 - SPY Price)

Each day (or whatever timeframe you're using), you'd perform this calculation to generate the composite price for that period. This resulting series is then plotted on a chart, forming the composite chart.

Interpreting a Composite Chart

The interpretation of a composite chart relies on understanding how the individual price series interact within the combined chart. Here's a breakdown of key aspects:

• **Trend Identification:** A rising composite price indicates a bullish trend, suggesting that the primary security (Price Series 1) is outperforming the inverse or related security (Price Series 2). Conversely, a falling composite price indicates a bearish trend. Trend lines can be drawn on the composite chart just as they would be on a standard price chart to confirm these trends.
• **Support and Resistance:** Significant support and resistance levels on the composite chart can indicate potential turning points in the trend. These levels are formed by areas where the composite price has previously stalled or reversed. Fibonacci retracements can also be applied to the composite chart to identify potential support and resistance levels.
• **Divergences:** Divergences between the composite price and other technical indicators, such as the Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD), can signal potential trend reversals. For instance, if the composite price is making higher highs, but the RSI is making lower highs, this is a bearish divergence, suggesting the uptrend may be losing momentum.
• **Breakouts:** A breakout above a resistance level on the composite chart can confirm the continuation of an uptrend, while a breakdown below a support level can confirm the continuation of a downtrend. Volume analysis is crucial when interpreting breakouts on a composite chart – higher volume typically indicates a more significant breakout.
• **Zero Line Crossovers:** While not always present depending on the constant used, if the composite chart crosses the zero line, it can indicate a significant shift in the relationship between the two price series. A cross above zero suggests the primary security is gaining strength relative to the inverse, and vice-versa.

Applications of Composite Charts

Composite charts have a wide range of applications in technical analysis:

• **Relative Strength Analysis:** Combining a stock's price with a market index (like SPY or the Nasdaq Composite) allows traders to assess the stock's relative strength. If the composite price is rising, the stock is outperforming the market.
• **Sector Rotation:** Comparing the price of a sector ETF with the price of a leading stock within that sector can help identify sector rotation opportunities.
• **Currency Pair Analysis:** Combining the price of a currency pair with a related commodity (like oil for USD/CAD) can reveal insights into the underlying drivers of the currency movement.
• **Intermarket Analysis:** Analyzing the relationship between different asset classes, such as stocks and bonds, using a composite chart can provide a broader perspective on market sentiment. Correlation analysis is a key component of this application.
• **Identifying Lead-Lag Relationships:** Composite charts can help identify which assets tend to lead or lag in a particular market cycle.
• **Confirming Trading Signals:** Using a composite chart to confirm signals generated by other technical indicators or chart patterns can improve the accuracy of trading decisions. Candlestick patterns can be particularly effective when analyzed on a composite chart.
• **Timeframe Combination:** Combining price action from different timeframes (e.g., daily and weekly) can reveal a more comprehensive picture of the trend.

Advantages of Using Composite Charts

• **Simplified Visualization:** Composite charts condense complex relationships into a single, easy-to-understand chart.
• **Enhanced Trend Identification:** The combined price series can make trends more apparent than viewing each series separately.
• **Early Signal Detection:** Divergences and breakouts on the composite chart can provide early warning signals of potential trend reversals or continuations.
• **Improved Confirmation:** Composite charts can be used to confirm signals generated by other technical analysis tools.
• **Reduced Noise:** By combining price series, composite charts can filter out some of the noise inherent in individual price movements.

Disadvantages of Using Composite Charts

• **Complexity:** Constructing and interpreting composite charts requires a good understanding of technical analysis principles.
• **Constant Selection:** Choosing the appropriate constant is crucial for accurate interpretation and can be subjective. An incorrect constant can distort the chart and lead to false signals.
• **Data Requirements:** Creating a composite chart requires historical price data for all the price series being combined.
• **Potential for Misinterpretation:** The combined nature of the chart can sometimes make it difficult to discern the individual contributions of each price series.
• **Not a Standalone Tool:** Composite charts should not be used in isolation. They are best used in conjunction with other technical analysis tools and fundamental analysis. Elliott Wave Theory can provide additional context.
• **Subjectivity:** While mathematical in construction, the interpretation of patterns and signals on the composite chart still involves a degree of subjectivity.

Practical Examples

• • Example 1: Apple (AAPL) vs. SPY**

As mentioned earlier, combining AAPL and SPY can help assess Apple's relative performance. If the composite price is rising, it suggests Apple is outperforming the broader market. If the composite price is falling, it suggests Apple is underperforming. Looking at the RSI on this composite chart can add further confirmation.

• • Example 2: Gold (XAU/USD) vs. USD Index (DXY)**

Gold is often considered a safe-haven asset and tends to move inversely with the US dollar. Creating a composite chart using Gold and the USD Index can help visualize this relationship. A rising composite price suggests Gold is strengthening relative to the dollar. Applying Bollinger Bands to the composite chart can help identify overbought and oversold conditions.

• • Example 3: Crude Oil (CL) vs. Energy Sector ETF (XLE)**

Analyzing the relationship between crude oil prices and energy sector ETFs can provide insights into the health of the energy market. If the composite price is rising, it suggests the energy sector is benefiting from higher oil prices. Ichimoku Cloud can be added to this composite chart for further analysis.

• • Example 4: Bitcoin (BTC/USD) vs. Nasdaq 100 (NDX)**

Bitcoin's correlation with the Nasdaq 100 has fluctuated over time. A composite chart can help visualize this evolving relationship. A rising composite price suggests Bitcoin is behaving like a tech stock, while a falling composite price suggests it's diverging from the tech sector. Using Average True Range (ATR) can help measure volatility on the composite chart.

Advanced Considerations

• **Weighted Composites:** Instead of simply adding the price series, you can assign different weights to each series based on their relative importance. This can be useful when analyzing assets with varying degrees of influence.
• **Multiple Composites:** Creating multiple composite charts using different combinations of price series can provide a more comprehensive view of the market.
• **Dynamic Constants:** Instead of using a fixed constant, you can dynamically adjust the constant based on market conditions.
• **Combining with Other Indicators:** Overlaying other technical indicators, such as moving averages, MACD, and RSI, on the composite chart can enhance its analytical power. Stochastic Oscillator is another useful indicator to consider.
• **Automated Charting:** Many charting platforms now offer built-in tools for creating and analyzing composite charts, streamlining the process.

Composite charts are a powerful tool for technical analysts who are willing to invest the time and effort to understand their intricacies. While they are not a magic bullet, they can provide valuable insights into market dynamics and improve trading decisions when used in conjunction with other analytical techniques. Mastering this technique requires practice and a solid understanding of chart patterns, support and resistance, and other core concepts of technical analysis. Remember to always practice proper risk management when trading.
