Weights. Enter the weight for each quarter of the time period. The
number of time periods in the ERS calculation is broken into 4
equal-sized pieces so you can assign different weights
to different parts of the data (for example, you might want to put
more weight on recent data). The calculation that you see in the
Investor's Business Daily newspaper usually puts more weight on the
recent data. A good approximation would be 40%, 20%, 20%, 20%. The
weighting calculation divides the number of time periods you specified
by 4, then takes the dollar change in each quarter, multiplies by the
weight specified, adds the four weighted changes together, and then
converts back to a percentage.
I use the same percentages but a lookback period of only 120 days.
Your choice. Higher percentage in first box means more emphasis on
recent data. You can make it 100%.
