The Economics of Technical Analysis: Identifying the Branch and Its Relevance
Technical analysis, a branch of financial study, involves the examination of past market data, such as prices and volumes, to predict future trends. This practice, commonly used by traders and investors, relies heavily on indicators like the Moving Average Convergence Divergence (MACD), Commodity Channel Index (CCI), and Relative Strength Index (RSI). But where does technical analysis fit within the broader landscape of economics and financial science? Let's explore this intriguing question and whether technical analysis has economic validity.
Understanding the Scope of Technical Analysis
Technical analysis has been a subject of fascination and controversy for decades. The idea that past market data can provide insights into future price movements is both compelling and, at times, criticized. My own journey into technical indicators spanned at least a decade, during which time I not only analyzed these indicators but also designed a few of my own. Despite the abundance of resources available on the topic, a cursory look at Amazon reveals over 10,000 books on technical analysis, yet the number of market millionaires one can identify from these resources is relatively small.
Where Does Technical Analysis Fit Within Economics?
The question of whether technical analysis belongs to a serious branch of science is often debated. The technical analysis community tends to argue that it is a robust method for predicting market behavior, while economists and scientists argue that it lacks a solid theoretical foundation. One of the primary reasons for this skepticism is the difficulty in creating a controlled environment for testing technical indicators. Most scholarly attempts to validate technical indicators have been conducted under limited circumstances, where the indicators have shown varying degrees of success.
Evaluating the Success Rate of Technical Indicators
In an ideal environment, one would expect technical indicators to perform consistently over time. However, numerous studies have shown that the success rate of simple technical indicators is often around 50%. For instance, when researchers run studies on the same dataset designed to control for external variables, the results are often inconsistent. The effectiveness of an indicator can only be verified after an event has occurred, which limits the utility of these studies in a practical trading or investment context.
The False Hope of Combined Technical Indicators
A common belief among traders is that stacking multiple technical indicators can help reduce the noise and improve accuracy. While this approach might sound reasonable, it does not necessarily lead to better results. Just as adding a faulty component to a car that already works 50% of the time does not improve its overall performance, stacking indicators with low success rates does not necessarily enhance the reliability of the system.
Bringing Technical Analysis Back to the Real World
To assess the viability of technical analysis, it is essential to go beyond the technical domain and evaluate its practical application in the real world. If we consider a hypothetical car that works 50% of the time, would adding a battery and other components that also work 50% of the time make the car more reliable? The answer, typically, is no. Similarly, relying on a series of indicators that work only 50% of the time is unlikely to provide consistent and reliable insights into market behavior.
Conclusion: The Need for a Strong Theoretical Foundation
In conclusion, while technical analysis can provide valuable insights for short-term traders, its lack of a strong, theoretical foundation often raises questions about its long-term effectiveness and economic validity. As we move forward, it is crucial for the technical analysis community to engage with economists and scientists to establish a more robust framework for evaluating these indicators. Until then, it's important to view technical analysis with a critical eye and recognize its limitations.
