    Question how to calculate weekly and monthly percentage returns from daily figures

    Hi,
    I am only a spreadsheet newbie. Am trying to tackle a financial drama. I have a column of dates going back in time over a thousand days (in date order) and an adjacent column of figures that show historic daily percentage movements in the value of an investment for each of those days.

    I need to be able to calculate what the percentage return has been on a weekly basis, as well as on a monthly basis, because it appears I was tricked by false advertising for an investment.

    About half the daily returns are positive eg 0.121561% and about half are negative eg -0.115487. Some days however show zero change.

    I need to be accurate as the outcome will form basis of a complaint which they will certainly shoot down if not correct.

    To be accurate the calculation must occur on a day by day basis, in that figures for one week can’t be simply added together then divided to get an average. Also the daily figures for most individual weeks are a mix of positive and negative percentage movements.

    this is a small sample cut.....
    15/08/2014 -0.0242
    14/08/2014 -0.0516
    13/08/2014 -0.2705
    12/08/2014 0.3081
    11/08/2014 0.2851

    So maybe there is a need to start each calculation on a base figure of say 100 then multiply by first percentage movement then multiply the answer by the next percentage movement, and repeat until end of week gives the weekly percentage movement. How to get the program to distinguish and calculate the negative and positive percentage returns sequentially on a day by day basis is something way beyond me unfortunately.

    As my hard drive failed recently, I purchased a new drive but unable to recover excel and other programs so have downloaded freeware spreadsheets, gnumeric and kingsoft in the hope of urgently completing this exercise. I think the excel process and formula might be identical to or close enough for me to adjust, to use in the alternate software....hopefully. Thanks greatly if anyone can help.
    regards,
    Ben Davis

    Re: how to calculate weekly and monthly percentage returns from daily figures

    G'day Ben.

    I was going to post a posible solution but as you don't have excel I'll talk you through it.

    Firstly I turned your data upside down, oldest to newest (seemed easier to me this way)

    then I assumed you don't have data for Sat or Sun dates

    Then with your dates in column B and your percentage movements in column C try this in cell D5 and copy down column D (note no data in first 4 cells of Column D as you're looking at the last weeks - 5 days data)

    This should give you the percentage movement in that 5 day (1 Week period)

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Thanks kindly Crooza,

    That's awesome.

    I experimented with the small cut section we are using for my learning purposes. Could not get it to work using gnumeric, because of me doing something wrong no doubt, but something happened when I followed your instructions using the Kingsoft 2013 spreadsheet program.

    The result was.......

    11/08/2014 0.2851
    12/08/2014 0.3081
    13/08/2014 -0.2705
    14/08/2014 -0.0516
    15/08/2014 -0.0242 -0.245939884

    The columns seem to disappear on pasting here, but the D5 result as you can see is -0.245939884 (% I hope). I don't know how to check if it is the correct answer. However it "looks" wrong considering the size of the first two days of positive returns. I think, from eyeballing the returns for each of the days in succession (imagine applying them to a starting value of say 100 one day at a time), that the weekly % return should be a positive number?

    regards,
    Ben

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Ben,

    Your logic is right. The number is correct but the sign is wrong. The formula should be (formula) -1 not 1- (formula). Change this and it will be right

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Thanks again Crooza,

    That was also h-u-g-e of you. I appreciate it greatly.

    The modified formula gave the correct answer in Kingsoft 2013 without any negative sign .

    I also worked it out manually on the PC scientific calculator just to prove to myself that the result was correct, which it was.

    Over the w/end i will try to make inroads into the project, being only an L plate spreadsheet driver.

    The list commences 01 July, 2011 and runs till present day.

    There are some variations in the list which I don't know will affect the structure of the formula or not eg 1. for the first few years it shows returns for each day of seven day week though in recent times weekend days show zero, 2. Some occasional other days show zero, 3. the earning rates are displayed to fourth decimal for part of the list, then to sixth decimal, then back to four decimal display in most recent period. 4. As daily earning rates can bounce from positive to negative to positive to negative all in one week, does the formula automatically recognize and calculate this?

    After I calculate the weekly returns I have to do the monthly return calculations which will involve calculating each day at a time starting first day of month and ending last day of month. Is it the case that because returns can bounce from positive to negative from one day to the next that there is no way of having shortened formula that spans the days of the month (up to 31 days)?

    Thanks again. I placed my retirement funds in the investment because they advertised low risk investment with negative returns only 2% of the time. All I have since learned is that there are 631 negative days on the list I have obtained. To my eyes it appears that negative weekly and negative monthly returns would also be occurring way more than 2% of the time but I have to prove it to have any cause for complaint and possible compensation. The power and speed of spreadsheets is awesome for a first timer.

    kind regards,
    Ben

    Yes the different time periods may be an issue. Send me the spreadsheet. If I can read it in excel I'll look at it.

    2. Some occasional other days show zero, 3. the earning rates are displayed to fourth decimal for part of the list, then to sixth decimal, then back to four decimal display in most recent period. 4. As daily earning rates can bounce from positive to negative to positive to negative all in one week, does the formula automatically recognize and calculate this?
    2. 0 won't be an issue the formula will handle that
    3. Order of accuracy won't be significant
    4. Yes negatives and positives are all handled in the formula

    Is it the case that because returns can bounce from positive to negative from one day to the next that there is no way of having shortened formula that spans the days of the month (up to 31 days)?
    That's right, you need to consider each movement in price so there's no shortcut that I can see.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Thanks again Crooza.

    Great and helpful answers.

    I've done some months of week to week outcomes, by modifying the code row numbers each time to suit, and so far your formula appears to be working flawlessly.

    Will be interesting to see what the end result turns out compared to their advertising of negative returns only 2% of the time. The monthly outcomes will carry the most weight. Sure looks like bad timing putting the whole retirement savings in on Sept 1 this year. It was advertised as no riskier than money in the bank.

    I will attempt to send copy to you as requested, don't know my way around internet forums. Would be grateful to know if it looks like I'm going wrong somewhere.

    kind regards,
    Ben

    Couldn't find button where to upload and send attachment from one forum member to another. Will have another look at it later today. Cheers.

    Crooza, I tried but got a knock back on the file type for some reason. I've made a screenshot image of the message which, hopefully will post. I might try and change the file extension to see if it will trick the program into uploading the file.

    How big a file is it? I think the forum has a limit at about 1Mb. If it's too big, just send through enough data to give the idea.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Is only 91kb. I'm wondering if because it is a competitor file (Kingsoft) and not excel, it gets knocked back. I'll try to rename and see how it goes, if not can paste some of it as you suggested.

    I don't know if excel will read it though, although kingsoft spreadsheets is supposed to handle excel files.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Hi Crooza,
    This is a cut part of how much I have done, as I've been thinking excel probably does not read Kingsoft spreadsheets. I hope it is accurate. I'm hoping to learn how to make graphs and charts from the data in future. Thankyou for the code. I would have got nowhere without it.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Ben

    Sorry haven't had a chance to look at the zip file. Looking at your data above I'm wondering if you want to have flexibility to determine over different time periods if you might be better creating a new column that works out the percentage movement from the very first data point (a bit like the CPI listing) so you can compare any two dates. To construct that column start at the very first data point and simply multiply each percentage movement by the previous one. Ie if the formula is in column E e1 = 1, E2 = E1 *(1+rate/100) where rates is c2 or wherever your daily rates are then copy E2 down. I won't get a chance to play with it today but I'll look at it tomorrow for you.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Unfortunately the columns got lost on pasting. I used row A for column headings.
    A - day
    B - date
    C - daily rate
    D - week no.
    E - weekly rate
    F - month
    G - monthly rate

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Ben,

    Zip file won't work for me. I've got this working for month and weekly data like I described above for the sample data you sent through. I can do the rest of your data if you upload a file - say a csv file or even a text file and I'll convert it. I'll send back the formatted data as either an excel (although that i realise is an issue) and / or a text file for you to convert back

    Hi Crooza,

    Am having a few PC gliches as well as nodding off . Age. Your offer is .... huge. I feel guilty about it, considering how helpful the code you sent already has been. In fact I borrowed two excel beginner books today cos I'd like to understand it and be able to make charts etc.

    If you're busy or otherwise occupied plse say so and I'll complete it in my plodding way. I'm not letting 'em off the hook as they cost me sleep and dollars with their false advertising and I'm gonna prove it using their own data.

    I'll try upload.....

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Last bit I have...

    I hope you know how to get the program to put the data into 3 columns. If not, plse don't tackle it at all.

    weekly and monthly rate changes.txtBen,

    Only took about 5 minutes so don't feel bad (but you better do a manual check just to make yourself confident that it's right)

    I've attached the spreadsheet just in case your program can read it - that way you can look at the formulas and the way I've structured the data. I've also added two text files in case you can't read it with the detail and the monthly summary.

    If you find errors let me know.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Crooza,

    What you've done and sent is sooo excellent. Will do some checks in my slow style. I guess all the posts reflect my rank learner status, with an advanced problem The Kingsoft spreadsheets program opened it up no problem. Good freeware.

    I like also how when I click on a cell I can see your formula, so the document will help my learning and understanding of formula.

    7 negative months showing and no doubt Sept this year would also be a negative month if I get more current data. That will make 8 negative months in 39 months. Too volatile for me. I put the retirement funds in on Sep 1 cos they advertised risk as no greater than money in the bank with negative returns expected only 0.4 of a year over 20 year period which = 2% of the time. Their negative monthly returns are occurring at around 20% of the time.... 10 times more frequently than advertised and even worse than I thought. I'll give them opportunity to compensate me for losses, otherwise formal complaints to ombudsman and also trade practices regulator for false and misleading advertising will be happening.

    The only thing I noticed was the monthly figures show beside the 1st day of the following month eg the last day of the first month finishes at row 32 and the monthly figure shows in row 33 being the first day of the next month. Maybe that is the proper protocol, I wouldn't know. I looked at the monthly calculation formula, but was too advanced for me.

    Thanks so much. You're an excel guru and legend in my book.

    Ben

    Re: how to calculate weekly and monthly percentage returns from daily figures

    weekly and monthly rate changes.xlsx

    Ben,

    try this. You're right I should have used the last day of the month not the first day of the month. (the formula was slightly easier for the first of teh month becasue each month has a first but the last day of the month was different due to there being differnt days so I had to work around that). Anyway I sorted it out. I've left both columns in the spreadsheet.

    As always. Please do a manual check to make sure the numbers are what you want

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Crooza,

    Thanks for the new monthly figures.

    I’m not sure whether my alternate software might be the reason, but there is no value showing for the first month, or for Dec 2011. It just says #N/A.

    The revised monthly calculation also shows a result for part month Sep 2014, but shows a positive figure which can’t be right looking at the disasterous Sep 2014 daily earnings rates.

    There “looks’ to be a fair variation for some months just from a one day adjustment. Dec 2012, as an example, shows a fair size positive gain. In practice I think the 0.019504 has been added into the calculation (the first day of the month) and 0.060162 has been removed from the calculation (being the first of the following month). So a larger positive return was removed than was added yet the new monthly figure shows that the monthly return increased significantly?

    My brain has trouble properly grasping the compounding effect of percentages when they cycle between positive and negative.

    As part of grasping the changes if I look at May 2014, the last day of month was a zero day (so no changes at that end of month needed ) and the first day of month was a negative figure. Therefore the new monthly figure, is it just a case of applying the negative day to the previous monthly calculation for May? Or does every day need to be calculated separately starting with the negative day of the first of the month.

    I’m not sure of the correct approach to manually check new monthly versus previous monthly figures. To remove the last day (being the first day of the following month) from the original calculation would be easy, but I “think” I have to include a first of month day at the beginning to complete the adjustment? If so, I think, to be correct, I would need to then follow a very much longer process and start raw from first day of the month and calculate each day manually up to and including last day of month, then check result against the new monthly calc’s?

    A shortcut approach I thought might be to starting with the first of the month figure then apply the original monthly figure to it, then slice out the last day of the original monthly figure (as it was actually the first day of the next month per the original formula.). But again I suspect this approach would not be accurate, because once an additional day is added at the beginning then I ‘think’ each subsequent day would need to be calculated one at a time to be accurate? I’ll need to be as accurate as I can because no doubt the Fund would employ some spreadsheet aces, who’ll try to discredit my evidence of their false representations. Sorry this post is a bit long winded. Your separate "index" also makes for Great ammo in identifying significant negative return periods.

    thanx & regards,
    Ben

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Ben

    apologies, I had the old file working and forgot to save it and the one I posted up was a working one which had the wrong formulas in it. I should have been more careful. This is the one you want and I've just gone through it and checked the first few months entries. I should have checked it. Again I apologise.

    try this one as I'm much more comfortable with it. I think all your issues above are related to me giving you the wrong file so try again with this one.

    By the way while the formula I used was to automate everything if you want to manually check just look at how I did the index ratio. the index for date 1 / index for date 2 -1 will give you the percentage difference between the two dates so you can check any period you want with this formula

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Crooza,
    Very excellent help once more, and no apologies needed at all. I’m very lucky to have received such help from a very decent person, and very smart cookie at that.

    I have downloaded the file and will go over it tomorrow, when brain is not so fatigued. The last monthly return, for part Sep 2014, doesn’t appear right to my eyeballs, from glancing the string of daily negative returns received, espec -0.5138 on 11.09.2014. The return I think should be significantly more negative.

    I’ve noticed from the “index” column, that you so wisely suggested and included, that there are also variations between the actual annual returns (based on their data) and their advertised annual returns (according to my math).

    They advertised historic annual returns of 10.13% for 2011/12, 2.35% for 2012/13, and 5.17% for 2013/14. According to my check against the index column the first year was confirmed as correct, but the second and third years came out as 1.91% and 5.08% respectively. So this appears to be more false advertising that I can make reference to, although I will double check my calc first. Thanks.

    regards,
    Ben

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Ben,

    the numbers you refer to are right but I should have explained what I did. I don't like using percentages, I rather use absolute numbers. Your data came across in the original file as percentages so 0.5 (0.5%) in your data in real terms is 0.005 or 0.5/100.

    In the weekly data I convert by multiplying and dividing ny 100 where necessary to do the calculations.The weekly figures were displayed as percentages (so you can compare directly with the daily figures). When I did the monthly figures the formula was so convoluted that I didn't do thie and I'm so used to reading numbers in their raw form I automatically convert them to percentages in my mind. What I didn't do was tell you

    So the numbers were 'correct' but not presented as percentages. I've corrected this now and attach a modified workbook. This should make your Sept 14 figures match up with your daily figures.

    Thanks for checking.

    Re: how to calculate weekly and monthly percentage returns from daily figures

    Crooza,
    Thanks again. I spent some bits of time going over it, and learning basic code language. I will have to look closer at your changes during tomorrow. Thanks so much.

    For me to manually check monthly returns I have thought that rather than one day at a time it would be so much easier to simply compare the figures for the last day of each month using the “index” column, seeing how it is record of running percentage changes eg if last day of one month was 120 and last day of next month was 125 then monthly % return would be:

    (125-120) / (120/100) = 4.1666666666666666666666666666667

    Can you see any risk in this approach? It does rely fully on the Index column being 100% accurate which I guess it must be, although there is a difference between the two most recent yearly returns that the Fund advertised and what I came up with from using the index column figures as basis for my check.

    Is there any way that the index figures could be inaccurate or partly inaccurate? It “looks” like the same code runs from start to finish so my thinking is the Fund must have falsely advertised higher than actual returns deliberately for last two financial years. Unless they topped up this particular investment option out of their reserves rather show the real returns.

    I made my first spreadsheet chart from your index figures, though I hardly knew what I was doing. I hope to progress to one that will highlight the discrepancy between their actual periods of negative returns and what they advertise.

    regards,
    Ben

    Ben,

    Sorry for delay. Been caught up on other matters.

    I checked your annual figures and I agree with your working. Your methodology seems sound to me. The index column should be correct providided the daily movements you provided me originally were correct.

    Well done on the chart. In teh attached above is anotehr example of a chart which will show the historic trend
