When reconsidering Dow Theory, it's interesting that despite being over 100 years old, it still functions as a fundamental principle of market analysis today. The theory proposed by Charles H. Dow is not merely a historical relic; it holds practical value even in modern trading environments.

Basically, Dow Theory is based on the idea of verifying market movements through multiple indices. For example, if both industrial and transportation stocks are rising, it confirms a genuine upward trend. This concept of mutual confirmation reflected the physical economic structure of the time. The transportation sector (mainly railroads) and manufacturing were closely linked, so a positive development in one tended to influence the other.

However, in modern times, this cross-index correlation does not always hold. Digitalization has reduced the importance of physical delivery, and the market structure itself has changed significantly. Still, the underlying philosophy of Dow Theory remains valid. The principle that a trend will continue until clear reversal signals appear applies equally to stock markets and cryptocurrency markets.

Looking at the price movements of digital assets, I notice that the three trend stages described by Dow Theory actually manifest. The primary trend indicates a long-term direction lasting from several months to years, within which secondary trends form medium-term corrections lasting from a few weeks to several months. The tertiary trend, which involves short-term price fluctuations, completes within days or hours.

Of particular interest are the three stages in a bullish market: accumulation, public participation, and over-enthusiasm/distribution. After a bear market, a period dominated by low asset values and pessimistic sentiment is the accumulation phase. Then, market participants recognize opportunities, and active buying begins, leading to a period of public participation where significant price increases can be expected. Subsequently, during the over-enthusiasm/distribution phase, market makers start selling their holdings. In a bearish market, these stages occur in reverse order.

The importance of trading volume is also a key element of Dow Theory. The idea that strong trends should be accompanied by high trading volume is still supported by many traders today. When volume is low, price movements may not reflect the actual market trend but could be temporary fluctuations, which is a useful warning.

Cryptocurrency markets operate 24/7, and sentiment has a significant impact. That’s why the psychological aspects of Dow Theory, confirmation through volume, and emphasis on trend persistence are especially valuable. The ability to distinguish between temporary fluctuations and genuine trend reversals is particularly crucial in digital asset markets.

Of course, critics point out that the idea of cross-index correlation is outdated. That’s a valid argument. However, the concept of market trends derived from Dow Theory—namely, that prices incorporate all available information—remains trusted by many investors and traders today. Differentiating between primary and secondary trends can be challenging, and many experience misleading reversals, but Dow’s recommendation to remain skeptical until a trend reversal is confirmed still holds value. Ultimately, even after more than a century, the core principles of market psychology and technical analysis have not changed much.
