GROUP ACTIVITY REPORT (Modified 05/06/04, explanation below)

This page contains explanations and descriptions for "GROUP ACTIVITY" reports. Each report will carry a link
to this page so those interested can gain a clearer understanding of the data reported. The report lists data for
209 Media General Groups. The data is developed from Worden Brothers software. The following describes how
the data is processed. (Updated 03/03/04, flg)

 
 1) All groups are processed daily. 
  . 
 2) Each group has an accumulator to which values can be assigned. 
  . 
 3) If a group has a volume greater than it's 90-day average volume 
  . 
    if the change in the group's index is positive 
        (i.e., if the group went "up" today) 
      3 is added to the group's accumulator 
     otherwise 
      3 is subtracted from the group's accumulator 
  . 
 4) If a group did not have a volume greater than it's 90-day average volume 
  . 
    if the group's accumulator value is greater than zero 
      1 is subtracted from the group's accumulator 
     otherwise 
      1 is added to the group's accumulator 
  . 
 5) special logic handles cases where the foregoing operations require a transition 
    between positive and negative values in the group accumulator. 
    (See modification note, below) 
  . 
 The information is recorded and reported in 5 columns, as follows: 
  . 
 GROUP - is the Media General Group Number 
 NAME  - is the group name 
 NOW   - is the current value of the accumulator 
 MAX   - is the greatest value the accumulator has attained on its 
         present run 
 DAYS  - is a visual indication of recent activity, as follows 
  . 
 Each day of the week is assigned a numeric and alphabetic value, like this 
  . 
 Monday     2 B b 
 Tuesday    3 C c 
 Wednesday  4 D d 
 Thursday   5 E e 
 Friday     6 F f 
 

The day of the week values for the current day are at the top of each report, as a guide.

If 3 was added to the accumulator today, the capital of today's letter is added to DAYS

If 3 was subtracted from the accumulator today, the lower case value of today's letter is added to DAYS

If today's volume was less than the 90-day average volume, an underscore is added to DAYS

Occasionally, a group's run will continue for an extended period. When the length of DAYS exceeds 34, the leftmost 6 characters are dropped and a left arrow character (<) is inserted to show that earlier characters have been dropped.

The bottom of the report has two information blocks:

The first shows the number of groups that exceeded their 90-day average volume today, how many of those were up and how many down.

The second gives a count of the groups which have a bullish accumulator (NOW values greater than zero), those which have a bearish accumulator (NOW values less than zero), and the sum of the accumulator (NOW) values. This last has proven to be an excellent indicator of the health of the market.

Modifications:

 
 03/28/04: stop discarding the content of DAYS under certain conditions 
   This change will leave about 30 days activity for each group.  Marks 
   indicate a group with volume above the 90-day average and the mark's 
   case shows whether the group was up or down on the high-volume day. 
  
 05/06/04: In item 3 of the description above, from "if the group's 
   index is greater than zero" to "if the change in the group's index 
   is positive (i.e., if the group went "up" today)"
