Mid-week market update: What happens when an ominously sounding Hindenburg Omen occurs when the market is oversold? David Keller described the three components of the Hindenburg Omen in an article:
- The market has to be in an established uptrend;
- Market breadth becomes highly bifurcated, as measured by the expansion of new highs and new lows; and
- A downside break in price momentum.
Keller characterized the accuracy of this signal as “ten of the last three market corrections”. A single signal hasn’t been very useful, but a cluster of signals puts me on notice of a significant risk of a correction. The accompanying chart shows the history of Hindenburg Omens (pink=corrections, grey=false positives). Does the latest episode qualify as a cluster?
The limitations of the Hindenburg Omens
Here are some problems with the Omen. The Hindenburg Omen has been less effective when applied to the NASDAQ. Investors has seen a cluster of Omens during the latest advance and the NASDAQ 100 hasn’t corrected.
The current episode is characterized by a narrow advance led by a handful of stocks, while the rest of the market has exhibited weak breadth, which are the precisely sort of conditions the Hindenburg Omen is designed to capture.
What happens when the rest of the market is so weak that it’s already oversold? The accompanying chart shows the recent history of the S&P 500 when all three of the following indicators were oversold in unison:
- NYSE McClellan Oscillator
- 10 dma of S&P 500 % Advance-Declines
- Percentage of S&P 500 above their 20 dma
