Excel formula help (may lead to follow up work)

I have a spreadsheet with the following information in separate columns:

* Historical daily S&P 500 index closing prices

* Dates of data

* Days of data

* One column I have the weekly change of the index.

I would like to create formulas that would calculate the following data points for each time the weekly change is greater than a certain percentage threshold:

1. % change 1 week away from the day the threshold was breached

2. % change 1 month away from the day the threshold was breached

3. % change 3 months away from the day the threshold was breached

4. % change 6 months away from the day the threshold was breached

5. % change 12 months away from the day the threshold was breached

It is necessary to account for days when the markets are not open when calculating the above % changes.

This should be pretty simple for someone who is well versed using excel. Please provide your best bid. This is an evolving project, so there is very real opportunity for add-on work.
