General Discussion

Point changes are useless for these kinds of purposes. A 1000 point change on a 40,000 point base is less meaningful than a 500 point change on a 15,000 point base.

Use percentages. Really.

If I say the price of a painting has risen by $1,000 dollars it makes a difference if the original price was 2,000. If the original price was $800,000 then 1,000 is hardly noticeable, and not meaningful, just noise.

Cut to the chase, use percentages.
