Dancing with the Trend

A New Breadth of Fresh Air

StockCharts.com has vastly updated not only its raw breadth database but now there are hundreds and hundreds of new market breadth indicators available to everyone.  This is not really an article but an information piece about StockCharts.com’s vast amount of breadth material and where to find it; plus, a little sales pitch at the end I thought I just throw in.  And just to help validate it all for many years I managed a lot of money using a large percentage of indicators that used breadth data.

An Example of the Value of Breadth

Market tops, also referred to as periods of distribution are usually lengthy, volatile, and extremely difficult to pinpoint the actual top except for the always 20-20 hindsight.  As traders and investors watch the market action and the financial media shows the major indices every market day (every 5 minutes), you must realize that all of the major indices like the S&P 500, NYSE Composite, and Nasdaq Composite are capitalization weighted indices.  The Dow Jones Industrial Average is a price weighted index and performs similarly.  Capitalization and price weighted indices are controlled or driven by their largest components, let’s say the ones that make up 10% of the index can account from 35% - 45% of the indices movement.  At one point the top 10 stocks in the Nasdaq 100 index accounted for 46% of its movement.


After a long bull run in the market and prices begin to become more volatile and the overall trend has been reduced, it is not uncommon for investors and traders to seek some safer holdings.  These holdings are generally large-cap and blue chip stocks; they exit out of their riskier holdings such as growth and small-cap stocks.  This unified action causes the capitalization weighted indices to continue to move higher as more and more investors sell the small and mid-caps for perceived safety in large-caps.  Breadth on the other hand, where all stocks are created equally, will show a declining trend.

Let’s take the year 2007 as an example to show the importance that breadth contributes to market analysis.  After a good bull run from early 2003, the market’s overall trend was reduced early in 2007 but still making higher highs.  Breadth, using the ubiquitous advance decline line, declined during the entire year (see chart below).  This is because fewer and fewer stocks were participating in the perceived rally.  The Troops were no longer following the Generals. My friend Tom McClellan likes to say that breadth arrives at the party on time but always leaves early.  Back when I was managing money I used a model that consisted of 40% breadth indicators.

After using breath for decades I would state the following about breadth and market tops.  Breadth can and will show deterioration (divergence) while price based indicators move higher at every market top, it also can and will display it at times when there is only a pullback or correction.  One cannot assume that a divergence with price and breadth will be a trading opportunity, but it will always be a time to become more alert.  This is not unlike many economic indicators, recalling the humorous adage that the Index of Leading Indicators has called 18 of the 12 recessions.  Remember breadth treats all stocks equally.  Exxon Mobile could be up $35.00 one day and Bubba’s Pizza could be down $0.01 and they would cancel each other out using breadth.

There are 3 sections below, one for the New York Exchange data, one for the NASDAQ data, and one for the Toronto TSX data.  The raw data symbols and their starting dates are included for both the daily data and the weekly data.  After each table are links to various other breadth data and indicators in StockCharts.com’s Symbol Catalog.

A brief sales pitch to follow:  I am proud to announce that after over a year of work with many of the fine folks at StockCharts.com, the book is now available in Kindle format from Amazon.  You can CLICK HERE to go to the Amazon page.  I priced it to sell – only $19.99.  It has lots of new material from Tom McClellan, George Schade, and Dick Arms, plus all of the charts are from StockCharts.com.  Plus, an entirely new chapter (11) on non-internal breadth indicators.

And even more good news, we (StockCharts.com and I) have created a ChartPack that has all of the charts in the book, not only for the New York Exchange (in the book), but also for the NASDAQ Exchange and the Toronto Exchange.  The ChartPack has 187 charts for the NYSE, 187 for the NASDAQ, and 148 for the TSX Toronto.  Toronto is slightly fewer because not all of the breadth data was available, in particular, the weekly breadth data.  CGMBI ChartPack – Click Here.  This ChartPack means that you have every chart in the book plus the NASDAQ and TSX versions updated each day (each week for weekly data). That's well over 500 charts. The ChartPack is only $49.95 and is good as long as you are a subscriber to StockCharts.com.  The other really nice feature of publishing with Kindle is that if I want to add something to the book, say I discover a new breadth indicator, I can do so.  And everyone who bought the book will receive the update for free.

I feel the need to apologize for this article as I have been hooked on breadth since the 1970s.  In fact, the reason I wrote my “breadth” book is because It had not been adequately covered before.  The apology is for those of you who also get hooked on breadth and its various benefits and uses.  You could be playing golf.

Trade with Good Breadth,
