Darvas vs. The Turtles: A Comparative Analysis of Two Legendary Trend-Following Systems

Two Paths to Trend-Following Glory

In the annals of trading history, few strategies have captured the imagination of traders like the Darvas Box theory and the Turtle Trading system. Both are legendary trend-following methodologies that have been credited with generating immense fortunes for their creators and followers. While they share a common philosophical foundation – the belief that the trend is your friend – they are distinct in their application and execution. This article will provide a comparative analysis of these two iconic systems, exploring their similarities, their differences, and the timeless lessons that they offer to the modern trader.

The Darvas Box: A Visual Approach to Momentum

The Darvas Box theory is a visual and intuitive approach to trend following. It is based on the simple yet effective concept of a "box," a price range that a stock trades within during a period of consolidation. The breakout from this box is the signal to enter a trade, and the subsequent formation of new, higher boxes is the signal to trail the stop-loss and let the profits run. The Darvas method is a highly selective strategy that focuses on a small number of leading stocks that are making new 52-week highs. It is a discretionary system that requires a significant amount of chart analysis and a deep understanding of price action.

The Turtle System: A Mechanical Approach to Breakouts

The Turtle Trading system, in contrast, is a purely mechanical approach to trend following. It was developed by Richard Dennis and William Eckhardt in the early 1980s as part of a famous experiment to see if trading could be taught. The Turtles were given a set of rigid rules for entry, exit, and position sizing. The entry signal was based on a breakout to a new 20-day or 55-day high, and the exit signal was based on a breakout to a new 10-day or 20-day low. The Turtle system is a highly diversified strategy that is designed to be applied to a wide range of markets, from commodities to currencies to stocks.

Key Differences: Discretion vs. Mechanics, Concentration vs. Diversification

The most significant difference between the two systems is the role of discretion. The Darvas method is a discretionary system that relies on the trader's ability to identify valid box formations and to interpret the price and volume action. The Turtle system, on the other hand, is a purely mechanical system that is designed to be traded without any discretion. Another key difference is the approach to diversification. Darvas was a proponent of a concentrated portfolio, while the Turtles were taught to trade a highly diversified portfolio of markets. This reflects a fundamental difference in their philosophies. Darvas believed in focusing on a small number of high-conviction ideas, while the Turtles believed in spreading their risk across a wide range of markets.

Similarities: The Power of the Breakout and the Importance of Risk Management

Despite their differences, the two systems share a number of important similarities. Both are based on the power of the breakout, the idea that a move to a new high is a sign of strength and a potential entry signal. Both systems also place a strong emphasis on risk management. Both Darvas and the Turtles used a disciplined stop-loss strategy to protect their capital, and both understood the importance of cutting losses short and letting winners run. In this sense, they are both classic trend-following systems that are designed to capture large, sustained moves in the market.

Lessons for the Modern Trader

So, which system is better? The answer, of course, is that it depends on the individual trader. The Darvas method is more suitable for traders who are comfortable with a discretionary approach and who have a talent for chart analysis. The Turtle system is more suitable for traders who prefer a purely mechanical approach and who want to trade a diversified portfolio of markets. Ultimately, both systems offer a timeless lesson in the power of trend following and the importance of a disciplined, rule-based approach to the markets. By studying these two legendary systems, the modern trader can gain a deeper understanding of the principles of successful trading and can begin to develop a system that is right for them.
