Correctly Defining “Bear Market”

weekly Chart In Focus

I am starting a personal crusade to expunge the notion of “10% is a correction and 20% is a bear market” from our collective lexicon.  It is among the most meaningless, useless, and untrue statements out there.

The reason I dislike it so much is that it offers no insights about what a trader or investor should do.  If you find the market down some percentage, and conclude that, okay, it is a “correction”, then so what?  What does one do next?

Extended Data

All of this data, plus a lot more, is available on our Daily Edition along with charts and analysis.  See our Market Reports page to get the bigger picture.

Market Breadth Data Notes

  • We use WSJ/Barron's data for our final breadth numbers. Calculations made on numbers from other sources will show a slightly different result.
  • We wait until late in the day in order to have access to the "final" numbers.
  • This reflects final readings for the indicators covered.
  • Values for indicators calculated using preliminary numbers released just after the close usually differ slightly from these numbers.
  • We usually recommend that readers keep their own data for themselves, but this is a useful way to check and see if your numbers agree with ours.

Starting 3/8/2012:
NYSE Up Volume & Down Volume data will report composite trading volume.

3/7/2012 and before:
Reports NYSE floor trading volume, as has been our long standing practice.
