Ranking Industries |
Ranking IndustriesJames A. Andrews May 15, 2007
___________________________________________________________________________ A promise was made to focus on broader industry issues. Industry rankings are useful to the short-term trader. Leading and lagging industry lists explain how industries have performed on a relative basis. However, these lists say little about how industries have performed in absolute terms, how their rankings are currently changing relative to one another and how rankings are likely to emerge in the near future. This month, the newsletter explains how to gather this information quickly to identify the leading companies in leading industries. ___________________________________________________________________________
1.0 Industry Rank
Two factors are taken into account when industries are ranked at this website. About 90% of an industry’s rank is weighted by the percent increase in its index price over the previous 4 weeks and 10% is weighted by how much the index is oversold based on its 10-period Williams-%R. This definition is used for a trend following trading system with a two to ten day options trading period. Other criteria for industry performance can be defined for different trading systems and periods.
Industries are ranked from a high of 1 to a low of 215 based on a list of 215 industries that is maintained at Yahoo Finance. The Yahoo industry classification provides a finer breakdown of major sectors by a factor of one and a half to two compared with other classification systems. This has certain advantages. For example, last week the personal computer industry was ranked 11 out of 215 while computer based systems was ranked near the bottom at 203. Placing all computer companies into one industry index can give an incomplete picture.
There are some disadvantages also. Yahoo is still learning how to maintain its industry classification system. Stock splits cause the system to break down, skewing a composite index value by more than 50%. It is obvious when this occurs and requires checking. A one-day move from the first to the last position is a sure tip off. On May 10th, Trucks & Other Vehicles suddenly dropped by 59%. It turns out that Volvo had undergone a stock split. It takes several days for a composite index value to be corrected. This is the only major drawback found so far in using this system.
The main reason for using this classification system is the ready availability of industry performance. Each industry’s performance is accessible through online data retrieval software that imports the numbers directly from Yahoo Finance into a spreadsheet where they can be manipulated. Industry index values are updated continuously throughout the trading day. Industries can easily be ranked in the spreadsheet, as shown for the 40 leading industries in Table 1 and the 40 lagging industries in Table 2. The leftmost column is the rank. The second column from the left is discussed below. The third column from the left is the industry number. To the right of the industry name are five columns that show the percentage gain for each of the 4 previous weeks and finally for the entire month at the far right.

2.0 Changes in Rank
Industries ranked in a given position do not remain there for very long. Rank position changes over a given period lead to another possible way to rank industries that gives insight into how the ranking list could emerge in the near future. Relative industry rankings form a closed system. For every upward move in rank, there is an equal and opposite downward move by one or more industries. The sum of rank position changes in one direction equals the sum of rank position changes in the opposite direction. This concept allows you to rank industries according to how much their rankings have changed from their average value over time. The relative number of rank positions changed over time is a direct indication of the velocity of position movement. Positions continually change as illustrated by the second column from the left in Tables 1 and 2 where industries ranked closest to 1 are moving up the fastest. Those ranked closest to 215 are moving down the fastest.
This brings to mind two other lists, such as the one in Table 3 containing the 40 industries that are moving up in position the fastest. Toys & Hobby Stores? Where did they come from? Leading industries must start from somewhere. Before we know it, an under the radar industry pops up as one of the leaders. The missing industry for rising rank number 14 should be Regional Mid-Atlantic Banks. This is a software bug as the industry is tied at number 13 with Waste Management. There is no number 14, actually. Some way will be found to remedy this kind of occurrence. A list of the 40 industries declining in rank the fastest looks similar in Table 4.

Notice the change in color from green to red in the monthly gain column as you move from Table 3 to Table 4. Many industries changing the fastest are already near their respective top and bottom rankings. This bodes well for the lack of a major sector rotation, at least for the near term. Nevertheless, these changes in rank go on continually. For an options trader, it is good to make top down selections for buying calls from industries ranked in the top 40 and moving up in rank the fastest. Top down selections for buying puts can be made from industries ranked in the bottom 40 and moving down in rank the fastest.
The list of ranked industries can be charted to see more clearly the progress of an industry’s rise to prominence or fall from grace. The spreadsheet contains a chart for each of the above four tables. Only portions of the two most interesting ones are shown below. Figure 1 shows the 20 industries that are rising in rank the fastest and Figure 2 shows the 20 industries that are declining the fastest. The erroneous precipitous one-day drop in rank for Trucks & Other Vehicles can be seen in Figure 2. Both figures are as of the market close on 5/14/07.

3.0 Relative Rank
The important thing to note is that the usefulness of industry rankings depends on how each industry is actually performing. When the market performs poorly, the leading industry could very well be the one that declines the least. An industry could be doing nothing price wise but could end up near the top or bottom of the ranking list because other industries might be doing extremely poorly or well. There is not enough information in an industry’s ranking list alone to infer how the industry index has actually changed over time. Given the average industry performance or the percent change of the top and bottom ranked industries, one can only estimate how each of the remaining industries have performed. There is no substitute for looking at the actual percentage change of an index for the industry of interest.
