Instead of searching for the NAVs of all my funds at MyIRIS or MutualFundsIndia, I have developed a small excel sheet which will fetch the values for me and displays the current portfolio value at the click of a button. Here I am trying to share the “HOWTO” of the same.
- Create an excel workbook with 2 sheets. Call one as “NAVs” and the other as “Portfolio”.
- In the NAVs sheet, click at one of the top-left cells (I did on A2), and go to Data -> Import External Data -> New Web Query. [For more information on using Web Queries, visit Using Web Queries to Import Data to Excel @ R1C1.
- Now paste the url http://finance.indiamart.com/markets/mutual_funds/latest_mf_navs.html in Address box and press go. You would see something like this.
Say “Import”. Essentially what you have done is, creating an automatically updatable NAV list in the NAVs sheet. - Now select all Schemes in the imported table and define a named range as “fund_names” for it. [Creating Named Ranges in Excel]
- Now, go to “Portfolio” sheet and create a table like this.
[Click on it to Zoom] - Next select the Fundname column (I have 32 rows, you can have as many as you wish) and go to Data->Validation. Enter the settings like this.
- Formulas:
>>> For Purchase Value[f3]: “=e3*d3”
>>> For Current Value[h3]: “=g3*d3”
>>> For Current NAV[g3]: “=IF(C3=””,0,VLOOKUP(C3,NAVs!$A$6:$D$1634,3,FALSE))”
essentially, looking up for the selected fund name in the NAVs sheet and returning the exact NAV to this cell only if a fund name is selected.
>>> Gain / Loss[i3]: “=IF(ISERROR((H3-F3)/F3),””,(H3-F3)/F3)”
to avoid DIV 0 messages. - At the end of the table you can add a TOTAL row and repeat the necessary formulas to get the total portfolio performance.
- Now the portfolio tracker is done. Enter the fund data by selecting the fund name from drop down and number of units purchased, purchase NAV. Rest will be shown by the tracker.
- Remember: everytime you open the workbook, go to “NAVs” sheet and refresh the data. [Select anywhere in the table, right click and say Refresh Data]
Now this is a very basic portfolio tracker. I am thinking of adding some VBA / Macro so that everytime the table is refreshed, the new values are written in a separate sheet called “Historical NAV” so that we can track the fund performance over a period of time by selecting a date (instead of current date). Also, if we can import benchmark indices on runtime, you can get relative performance metrics. Plus, some more analysis of fund performances (instead of mere total return) would reveal the risk-returns of the portfolio. Lets see if I can build such a thing in my spare time.

An excellent solution, especially for large data sets.
Another solution without using solver would be to assign the player with the highest score to Team 1, the 2nd to team 2, 3rd to team 3, 4th to team 3, 5th to team 2, 6th to team 1, 7th to team 1 and it continues. This method would end up with a Std Dev of 0.001247219. This works best with a distribution with lower Std Dev for the dataset.
Full Disclosure: this is not my idea, remember reading something a few years ago. Think it may have been Ozgrid
thinking back I now remember why I read about it. About 10 years back I had to distribute around 300 team members into 25-30 odd teams. Used this method based on their performance scores. I used the method I described to do this and the distribution was pretty fair.
Solver would have saved me a ton of time though 🙂
I think the issue with you first Solver approach was that you took the absolute value of the sum of team deviations (which should always be zero except for rounding) instead of the sum of the absolute values (which is a reasonable measure of how unbalanced the teams are).
Here's another simple algorithm you could use: you start from the top (with players sorted from high to low), and at each step allocate the next player to whichever team has the smallest total so far. You can implement it dynamically with some formulas so it will update automatically when the data changes.
If the scores were more widely distributed (so that this might end up with not all teams the same size), you could add a constraint to only pick among the teams which currently have fewest players at each step, or just stop adding to any team when it hits its quota.
When I tried it on the sample, I got the three teams below, with a STDEV of 0.000942809 (i.e. about half of what Solver got to).
Team 1: John, Hugo, Tom, Josh, Eric, Zane, Charles, Andrew
Team 2: Barry, Michael, Kenny, Joe, Xavier, Patrick, Oliver, William
Team 3: Henry, Steven, Ben, Frank, Kyle, Edward, Cameron, Lachlan
Thanks for sharing!
Hi,
I was looking at all the solutions and this is closest to what I intended to do. I am dividing a bunch of players into 3 soccer teams. Players availability is also a factor while deciding the teams.
So the steps the excel needs to do is as follows:
1) In availability column if "yes" go to next
2) Equally divide 'Goalkeepers', 'Strikers', 'Defenders' basis their quality
So the end result gives each 3 teams a balance of players playing at different positions.
Can this be done on Google spreadsheet with only availability as an input from the user and rest calculates by itself.
Sorry for asking such a pointed question, but I have been struggling to find a solution for it for sometime now!
Hi Ishaan,
I am working on a similar problem at the moment, so I am wondering if you ever found a solution and if you are willing to share what you did.
Hi everyone, this is a variation of the famous Knapsack Problem https://en.wikipedia.org/wiki/Knapsack_problem.
I had to use a VBA implementation recently as part of a problem, where we ar trying to allocate teams of an organization into different locations (we are a large company with many different team). The goal was to optimally allocate teams to individual buildings without putting too many teams into one building and not splitting teams apart.
As we had around 400 teams of different sizes, solver couldn't handle it anymore. Luckily there is a Knapsack algorithm implementation in VBA readily available on the internet :).
I also went with a heuristic approach first!
An interesting mathematical solution but what if Eric and Xavier can't stand each other or Patrick is best friends with Steven - the real life problems that effect "even" teams.
@Joe
You can add more criteria like
If Eric and Xavier can't stand each other
=OR(AND(E15=1,E16=1),AND(F15=1,F16=1),AND(G15=1,G16=1))
It must be False
If Patrick is best friends with Steven
=OR(AND(E5=1,E17=1),AND(F5=1,F17=1),AND(G5=1,G17=1))
It must be True
Note that the 2 formulas above are exactly the same
except for the ranges
One must be True = Friends
One must be False = Not Friends
Nice Post!
Just one question What if number of players are not even or equally divisible.
Nice post Hui!
I download your workbook and just try to change in options the Precision Restriction from 10E-6 to 10-8 and the Convergence from 10E-4 to 10E-10. The process take almost the same time, but the results was great.
The standard deviation I got was 0,000471.
Team 1: John, Tom, Kenny, Frank, Eric, Xavier, Edward, Zane
Team 2: Steven, Hugo, Ben, Joe, Josh, Oliver, Cameron, William
Team 3: Barry, Henry, Michael, Kyle, Patrick, Charles, Andrew, Lachlan
Great application of Solver! Thanks for the link!
Great explanation. Well done... However, I tried with 6 teams of 4 players and solver never did finish.
How about vba code for the same data set.
I have 3 column A B C wherein A has text and B has number Wherein C is blank. And in C1 been the header C2 where I want the name to come evenly distributed the number which is in Column B.
My Lastcolumn is 1000.
Sorry if I'm being slow here, but how is 'Team Score' calculated? I've gone through the explanation several times but it seems to just appear.
@Hrmft
This process uses the Solver Excel addin
Solver is effectively taking the model and trying different solutions until it gets a solution that meets all the criteria
Then solver puts the solution into the cell and moves to the next cell
So yes it appears to "just appear"
Hi ! Thank you so much ! Works great 🙂
I cannot get the fourth Equation to work in my excel spreadsheet
You have =($E$2:$G$25=0)+($E$2:$G$25=1)=1 as a SUMIF solution, I have, =($F$2:$H$13=0)+($F$2:$H$13=1)=1 as my solution but it does not work. The only thing I changed is the ranges. Any suggestions?
Thank you.
Jim
