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.

A formula based approach will be complex and most likely inefficient - UDF might suit ?

Code: 
Function MinSignal(rngVals As Range) As Variant
    Dim vData As Variant
    Dim dblDiv As Double, dblTemp As Double
    Dim lngRow As Long
    Dim boolCalc As Boolean
    vData = rngVals
    dblDiv = Val(vData(1, 1))
    For lngRow = LBound(vData, 1) + 1 To UBound(vData, 1) Step 1
        dblTemp = Val(vData(lngRow, 1))
        If dblTemp > Val(vData(lngRow - 1, 1)) Then
            dblDiv = dblTemp
        End If
        If lngRow < UBound(vData, 1) Then
            If dblTemp < Val(vData(lngRow + 1, 1)) Then
                boolCalc = True
            End If
        ElseIf dblTemp < Val(vData(lngRow - 1, 1)) Then
                boolCalc = True
        End If
        If boolCalc Then
            dblTemp = (dblTemp - dblDiv) / dblDiv
            MinSignal = Application.Min(dblTemp, MinSignal)
        End If
    Next lngRow
End Function

can be invoked from Excel:

Code: 
=MINSIGNAL(B2:B68)

How to total the visible cells?
From the first blank cell below a filtered data set, press Alt+=. Instead of SUM, you will get SUBTOTAL(9,)
Hi,

Your welcome! - yes it can continue to find a maximum drop as data comes in but you probably need to tweak a couple of things:

  • In C3 enter: =IF(B3="",FALSE,B3-B2)
  • Define dynamic named ranges for the Columns A and B (for some nice explanations see excelisfun - http://www.youtube.com/watch?v=13tY16Y19TY or http://www.ozgrid.com/Excel/DynamicRanges.htm) as follows:
    • Name: adjClose, Formula: =OFFSET(Sheet1!$B$2,0,0,COUNTA(Sheet1!$B:$B)-1,1)
    • Name: date, Formula: =OFFSET(Sheet1!$A$2,0,0,COUNTA(Sheet1!$A:$A)-1,1)
    • Note - the rest of the column under the last row of data in columns A and B should be blank and there should be column headings in the first row for the dynamic ranges to work correctly.
  • Use the defined names to change F2 to =IF(F2<>"",INDEX(adjClose,MATCH(G2,date,0)),"")
  • Drag the formula's in columns C to I down as far as you want past the current set of data you have in Columns A and B. As new data is entered into A and B the rest of the columns should adjust accordingly.

Having said all this - you should probably use DonkeyOte's solution!

Not at all ... I should have clarified my assertion re: formulae to "single cell" formula which was my interpretation of OP requirements based on correspondence with Nate.
If helper cells are permitted then a formulae based approach should be fine (not to say UDFs should be disregarded - nor that mine is by any stretch optimal).

DonkeyOte,

Thank you for your suggestion, I have extremely limited knowledge in EXCEL, I would not even know where to start with your recommendation, I am sorry. I am basically copying and trying to understand what this formulas are doing.

I will do some research to see how I can insert this code you have provided. Thanks.

I have named range, thank you for help video. I am getting circular reference error message when I put in forumla in F2, if continued it shows following.

Here is a single helper column suggestion that you may wish to consider.

1. Enter a 0 in cell C2.

2. Formula in C3 is copied down.

(The 0.00% values mark the start of each 'descending' section)

circledchicken,

Thank you very much, it worked very well. Quick question, is there a way to pull start and ene date to adjacent cells of highest drop? that way I do not have to look for them.
Thanks. AD

Peter_SSs,

Thank you, your solution worked as well, it seems much streamlined. I have asked this question to circledchicken as well about pulling start and end date of drop, how do I incorporate that with your suggestion. Thanks. AD.
