Mystery of the Hindenburg Omen

June 23, 2008 – 12:00 am

 

The market tends to see a certain idea introduced which becomes a focus and nothing else matters.

The focus du jour for traders appears to be the Hindenburg Omen. This is a data-mined signal that is supposed to be an early warning of a market crash. The good thing about it is that it has worked relatively well in real-time trading, but the bad thing about it is that it gives a lot of false warnings.

Lately, we had two consecutive days with a Hindenburg Omen.The last two times it did so were last July and October, both excellent warning signs of more trouble to come. Historically, such signals have been more successful than not at highlighting times of heightened market risk over the next few weeks to a few months.

So what is a Hindenburg Omen? It is the alignment of several technical factors that measure the underlying condition of the stock market — specifically the NYSE —such that the probability that a stock market crash occurs is higher than normal, and the probability of a severe decline is quite high.

This Omen has appeared before all of the stock market crashes, or panic events, of the past 22 years. No panic selloff occurred over the past 22 years without the presence of a Hindenburg Omen.

Another way of looking at it is, without a confirmed Hindenburg Omen, we are pretty safe. But we have one as of October 19th, 2007. That first Hindenburg Omen signal expired October 13th. Then the markets generated a second comfirmed Hindenburg Omen cluster. The first observation occurred on October 16th, 2007. It was confirmed on October 17th. A total of observations occurred within this cluster.

How has this signal performed over the past 22 years, since 1985?

  • The traditional definition of a Hindenburg Omen is that the daily number of NYSE New 52 Week Highs and the Daily number of New 52 Week Lows must both be so high as to have the lesser of the two be greater than 2.2 percent of total NYSE issues traded tha day. However, this is just condition number one.

  • That the NYSE 10 Week Moving Average is also Rising (condition # 2),

 

  • and that McClellan Oscillator is negative on that same day (condition # 3).

 

Critics have taken this definition and pointed rightly to several failed Omens. A research done by Robert McHugh, Ph.D showed that if we add two more filters, the correlation to subsequent severe stock market declines is remarkable.

 

  • Condition # 4 requires that New 52 Week NYSE Highs cannot be more than twice New 52 Week Lows, however it is okay for New 52 Week Lows to be more than double New 52 Week Highs.

 

  • The fifth condition for high correlation is for a confirmed Hindenburg Omen. For the omen to be “official,” there must be more than one signal within a 36 day period, i.e., there must be a cluster of Hindenburg Omens (defined as two or more) to substantially increase the probability of a coming stock plunge.

TO RECAP: we have an unconfirmed Hindenburg Omen if the first four conditions are met, but the fifth is not , ie when we only have one signal within a 36 day period.

Once a second or more Omen occurs, we then have a confirmed Hindenburg Omen signal with substantially higher odds that a subsequent stock market plunge is coming.

Based upon the five parameters noted above, Confirmed Hindenburg Omens are very rare. There have been only 26 confirmed Hindenburg Omen signals over the past 22 years.

All the biggies over the past 22 years were identified by this signal as defined with the five conditions. It was present and accounted for a few weeks before the stock market crash of 1987,

We also need to take into account that the Fed could intervene by pumping liquidity as it did in September 2005 to stave off a crash. The Fed did the same in April 2004 but even with liquidity, the market fell 5%.

NOW the Omen is bandied about, and the crash is yet to come, unless condition # 5 occurs.This skin-of-the teeth confirmation says a lot for multiple strong confirming signals, for without the 5 conditions, it is easy to say the Omen is more a hype!
