Finding highest drop in value

[capex]

I need some help to automate process of finding largest drop percentages in a series based on following criteria:

1. These two columns represent S&P 500 value for last few months.
2. I am trying to find out highest drop in the series.
3. Drop in value starts if value is lower than previous day.
4. Drop in value stops as value goes up from previous day.
5. Example provided shows value drop in B3 from previous day B2, that event started the series and ended on B6 where value increased from previous day B5.
6. Highlighted cells is where drop started and ended with next day going up higher than previous day.
7. I am trying to find a formula which would find out
A. Each drop
B. Present only highest drop based on above mention conditions which is -11.18% from 8/3/2011 to 8/8/2011. Only interested in highest drop.
8. This series will continue daily as it unfolds, there could be many small drops along the way, want to see only highest one till another one goes higher than current one.

Thank you in advance for helping me out.

Hi, CC

Your suggestion of using dynamic range has helped me a lot, I have been manually changing all my formula so far as I add more data, I have lot to learn. Can not thank you enough. AD

 

[Peter_SSs]

Try this for Problem 2.

Note that the E2 formula is marginally simpler than the formula I used for Problem 1. This formula could be used for Problem 1 too if you want.

Problem 2

Peter,

You are genius.., thank you. How do I find trough date instead of end of cycle date, trough date is 10/3/2011 when it hit lowest in this cycle. Thank you very much for helping.

Peter,

Well, you could do it with the formula I have in the blue row. However, since that is such a large formula, it may be best (easier to understand and maintain) to break it up to the formulas I have in the green area. Your choice.

Note that this question has the same issue that I raised earlier. That is, it would be possible that the trough minimum value could occur several times within the cycle. For example, 1099.23 occurs on 3-Oct but could have also occurred on, say, 4-Oct and 21-Oct.

In that case, my formulas here would return the date that the minimum first occurs in the cycle.

Hi - I'm glad that helped.
If your looking for more resources to learn, I find the Excelisfun videos on youtube extremely helpful - http://www.youtube.com/user/ExcelIsFun
And there's loads of resources all over the place and this forum too ofcourse!
