Some Thoughts on the 'Hindenburg Omen' Pattern Predicting Market Instability

Tracking the Hindenburg Omen: How Much Danger Is There?

Warnings were heard from many corners of the financial blogosphere that the Hindenburg Omen triggered.

What is it?  It is a fairly obscure technical analysis pattern, which supposedly gives an early warning of unstable market conditions (and even potentially stock market crashes).

While the calculation is based on five factors, the primary conditions indicate that there is a big disagreement about market conditions.

For example, two of the conditions are that a substantial number of stocks have to be at yearly highs, while a substantial number of stocks have to be at new annual lows.  Ultimately, it is hard for those two conditions to be met in a short period of time, unless there's uncertainty in the market.  Moreover, after a rally, uncertainty is often a precursor to a decline.

In addition, technically (in order for the pattern to be complete), a second sighting of the five elements must occur within 36 days. Logically, lingering uncertainty is a momentum killer.  Well, in this case we have it; the pattern flashed in mid-April and it happend again on the last day of May.

 

 

While this pattern has correctly predicted every big stock market swoon of the past two decades, including the October 2008 decline (that set the global economic recession into motion), not every Hindenburg Omen has been followed by a crash. Resorting to a geometry analogy: All rectangles are squares, but not all squares are rectangles.

Personally, I don't make trade decisions based solely on indicators like this. Nonetheless, it has a pretty good track record, seems to be based on reasonable theories, and might be useful as just another data point urging caution.
