Introduction

In all my posts of the last few years I always include a metric which I call Troughs. This metric counts the number of times that the daily running balance falls x% after rising the same x%. For those who have a hard time with multiple drops in their portfolio this is an excellent metric for determining the degree of pain a strategy would have put you through. In the table that follows I have it set to a pain threshold of 5%. So every time the screen rises by 5% or more and then drops 5% it adds a new trough. What is most interesting about this metric is that it is much more predictive of future market return than either GSD (and this one by a huge margin) and also the Ulcer Index.

So if you want to find screens that will produce less pain this may be another indicator that you can add to your investor's toolbox. For the period that follows I'm using 1/1/2003 to 12/31/2006 using screens employing ranks 1-4. In other words, these are screens with higher volatility due to the limited number of stocks held.

In many ways this metric is similar to the Ulcer Index, but it only has a 68% correlation with it. It does have an 80% correlation with GSD, which is interesting since GSD does such a horrible job of picking high return screens going forward. In the table that follows if you sort by Troughs and choose the top five and ten screens these are the returns (CAGR) compared to sorting by GSD.
          Troughs    GSD
Top Five
24.91% 18.42%
Top Ten 25.50% 19.10%

So although they are highly correlated metrics, they are not equal as it relates to their ability to predict future performance -- of course, this is not what my little table is showing, but take my word for it, the one is far superior to the other for this purpose.

Index Troughs as a Comparison

Finally, here are some indexes to compare to the results above over the same time period. Keep in mind, however, that these indexes hold multiple securities, while each of the screens above only hold four. So if a screen can have a lower trough number than these indexes it is doing very well indeed.

These are screens with acceptable volatility -- GSD says it is high, but the Trough # says it is nothing to worry about.

If you want to keep your pain threshold to a low level, it may be a good idea to invest in screens with a Trough # below 15. Or develop a blend where the Trough # is below 15 even though the individual screens may have values above that.

Just a thought and something I consider in developing my own screen blends.
