Description Suresh PB 2020-09-29 12:33:41 UTC

SUMMARY
KMYMONEY Version kmymoney5-mingw64-5.0.6-8.1-setup.exe dated 29-Sep-2019 18:10 

Capital Gains Report not printing "Buy Value" when date sold is less than date bought. For example, in F&O you can sell the stock, and later buy.  This scenario is not printing buy value.  Hence the report is giving incorrect value.

STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT
When the stock is sold first then bought (future&option scenario allowed), capital gains report marks buy value as 0, then the report value is incorrect.

EXPECTED RESULT
Report should also print Buy value.

Example:

27-Sep-2020 sold xyxcorp 10 stocks at $12
29-Sep-2020 bought xyxcorp 10 stocks at $10

Here, the profit is $2x10 = $20

Capital gains Report indicates 10* $12 = $120

Expected profit is $20

KMyMoney simply does not handle this type of transaction.  You really can't sell something you don't have.  I don't claim to know the exact details, but I think it's actually done by buying a type of option to sell at an agreed price.  Then when you buy lower than that, you can sell at the previously agreed price.  KMyMoney does not handle options at all.  I also do not know if they will be included when KMM's investment handling is revised, but I don't think it's a high priority.

The current report is showing the capital gains of the sale, which is the entire sale price, since nothing had been paid for those shares.  That report (as far as I know) only reports realized gains; it does not mention the unrealized gains of the still held stock.  I'm actually tempted to call this a bug in allowing sale of shares you don't have.

I'll wait for other comments, but I believe this is a WONTFIX.

Yes, you are correct.  This is "option type" transaction where selling is allowed. I don't agree about considering transaction dates in chronological order of "Buy" and "Sell" in Capital gains report.  The fix is required only in Capital Gains report, otherwise product works perfectly fine.
