Wrong enty exit and differences in Momentify Portfolio and RZone backtest
-
Hello Definedge team,
I made a portfolio and invested through Momentify (after doing backtesing for several days ) on 01-Sep-25, I got 17 shares as per scanner conditions and strategy (Allotted 1 lakh on 20 stocks, but got 17 as per stock selection criteria). On 1-Oct-25 , did rebalancing as per rules , the strategy squared off 14 stocks and gave entry to 3 new stocks, so I have total = 17 -14 +3 = 6 stocks on 31st-Oct-25. Now rebalancing date is on 01-Nov-25 (Saturday is off, will do on 03-Nov-25). I got a mail for rebalancing, I checked the basket so it is showing 3 outing stocks and 3 incoming as per strategy criteria. All is okay till here because we have to rely on Momentify and don't have to do the changes manually as advised by Mr Prashant ji and it's the core and important idea of investing through this method for long term.
Now, out of curiosity and after reading some feedbacks of users about the wrong backtesting result and discrepancies. I ran the backtesting with same conditions of my real portfolio, same date i.e 01-sep25, it shows 17 stocks ( same result when I started), but next month on 1st-Oct-25, backtesting is showing entry of 4 stocks and exit of 1 stocks , so it makes 17-4+1 = 20 stocks for the month of October whereas in my real portfolio it made me exit 14 stocks and now I am holding only 6 stocks.
Pls look into this, how can we trust the backtesting? what is the point of spending hours with a hope of investing in good strategy through platform? it is really a serious issue, if such issues persist, I am afraid that, users will consider other alternatives available in market.
Hope to hear from you soon and you fix this issue asap.
Attaching backtesting result and real holding for reference.
Thanks & Regards, -

I got a call regarding this but I am not satisfied, they say, in backtesting it takes the Eod data and there might be some difference, to which I replied " yes, some difference, but in backtesting, next month(2nd month) it shows 20 stocks after squaring off some stocks n gave entry to some new one, while executing the real portfolio through momentify, I was left with only 6-7 stocks in my real portfolio and as far as eod data is concerned , momentify also pick stocks as per last day ending price."
So, I am bit confused and unfortunately can't rely on backtesting, it is good on paper, but in reality the story is completely different. The explanations I got , don't satisfy and encourage me to go further until they fix these issues. We are not putting only money, but investing our time and efforts. Thanks & Regards -
Hi,
Momentum investing simulator and Momentify rebalance - both are performing properly.
When you run Momemtum investing simulator for the same period - it calculates EOD data. For example the entry date is 1st. It will consider closing price of 1st for the calculation. While actual execution, Momentify calculates the entry price when you execute the basket. So, there will be a difference in backtested data and the actual execution. Even the number stocks will change. For closer to backtesting, you can execute the basket at around 3 pm on the selected date.I have mentioned this in the book and several times - the backtesting gives us the idea. There will be a difference in the performance while execution. Read this chapter.
https://shelf.definedgesecurities.com/master-momentum-investing-trading-strategies/chapter-10-backtesting/In the long run, the result will be close to the backtesting and it can even be better. There is no reason to doubt the backtesting or Momentum investing because of this. You can always crossoverify the backtesting data with the excel file and Momentify stocks with the strategy fields. You wouldn't find the discrepancy.
Let me know agar abhi bhi doubt hai.
