Hi:

What is the difference please between Price Change and Price Growth?

Also, what are the formulas please for Price Change-1 Yr and Avg Price Change-3 Yr

Thanks, Fred

The price percent change just uses the starting and ending values over the period while the price growth rate is based on a linear regression line of all of the prices.

Price Growth Rate Explanation

A 1 year price percent change in an daily time frame would be:

100 * (C / C252 - 1)

You would have to switch up to at least a 2 day time frame to calculate a 3 year price percent change.

100 * C / C378 - 1)

Annualizing this to one year (what I am assuming you mean by average price change) would result in the following (you would need to use the 2 day time frame for this as well).

100 * ((C / C378) ^ (1 / 3) - 1)
