I had some minor elective surgery last week and have spent the last four days recovering. With nothing to do except stay in bed, I had time to work on a new project. This project was to build some indicators that use only market breadth to operate- no price action– to time or make trades on one of the index ETFs, such as [[SPY]] . The overall goal was to have a measure of breadth that I could post nightly on the blog with the only requirement being that each measure had to have an edge.

The top pane is course a graph of the SPY.
The second pane calculates all stocks with a 50 day average volume greater than 100K and a 50 day average liquidity of greater than $1,000,000. It lists these as the “Universe” in blue. We can see that as of Friday there were 3,228 stocks that met this basic criteria. We then use this universe to measure the stocks in a uptrend (proprietary measure, shown by the gray histogram). On the right side of that pane we see in gray that there are 1,592 stocks in an uptrend. The second measure (the red line) calculates the number of stocks above their 5 day simple moving average. We can see that there are currently 2,102 stocks (out of our universe) that are trading above their 5 day simple moving averages.
I put the vertical line in to show how all the measures lined up to have you buy the bottom on 2/5/2010.
The other 3 panes need explanation as well, and a more detailed explanation will be forthcoming. Briefly, the 3 lower panes measure
- The cumulative Advance/Decline line of all stocks in the universe as described above
- A raw measure of advancers and decliners, with Bollinger Bands built from the decliners data.
- A measure of new highs and new lows with a 9 day simple moving average.
In the future I will cover what the specific buy/sell signals are for each of the measures, and with that we’ll look at how they performed under backtesting.
Currently, all the measures of breadth are saying that the market is overbought.
Back to bed…
