Hindenburg Omen frequently appears in U.S. stocks, signaling a warning to investors

Last week, the U.S. stock market showed a temporary rebound, but market experts still have serious concerns that have not been alleviated. Repeated risk warnings over a short period have increased uncertainty about stock price fluctuations over the next few months. According to McClellan, the author of the McClellan Market Report, a Hindenburg Omen warning signal was detected for the third time in just six days on stocks traded on the New York Stock Exchange.

The frequent appearance of this warning indicator is creating strong caution among market participants. Additionally, similar warning signals have been reported to have occurred consecutively since early fall of last year in the Nasdaq Composite Index, further deepening concerns about short-term market instability.

Lessons from the Past Show the Danger of Market Tops

Historically, the concentration of such signals often precedes market peaks. The most notable example was early 2022, when these warning signals appeared just before the stock market reached its peak. Subsequently, the market experienced a severe decline.

However, it is also important to note that the appearance of these signals does not necessarily lead to negative outcomes. There have been cases in the past where warning signals were detected but did not result in market deterioration, and discussions about the indicators’ reliability continue.

Understanding the Mechanics of the Hindenburg Omen

This indicator was devised by blind mathematician Jim Miekka in 1995, and its name is derived from the 1937 Hindenburg airship disaster. While the name sounds ominous, behind it lies a detailed calculation logic designed to measure structural risks in the market.

The Hindenburg Omen captures situations where, during high market levels, individual stocks show significant divergence in performance. This divergence indicates a loss of correlation across the market and potentially signals a risk of systemic price crashes.

Four Criteria for Warning Confirmation

A warning signal from this indicator is triggered when all of the following four conditions are met simultaneously:

1. Confirmation of an upward trend in the index – The 10-week moving average of the NYSE Composite Index is rising on the day.

2. Widespread new highs and lows – The percentage of stocks updating their 52-week highs and lows both exceed 2.2% (or 2.8% in some versions).

3. Relative superiority of new highs – The number of stocks hitting new 52-week highs is less than twice the number hitting new 52-week lows.

4. Technical bearish signal – The McClellan Oscillator is in negative territory on the day.

When these four factors act together, it suggests the market is unstable and may enter a rapid correction phase.

Recommended Investor Actions

The Hindenburg Omen is ultimately a statistical warning indicator and does not necessarily cause declines. However, the current situation, with multiple warnings occurring in a short period, can serve as a reason to consider risk mitigation from a portfolio management perspective.

Experts emphasize that investors should not rely solely on these technical warning signals but should also consider macroeconomic indicators and corporate earnings trends for comprehensive risk assessment. When the frequency of Hindenburg Omens increases, market sentiment tends to become more nervous, and a cautious approach is advisable.
