Trying to figure out ROI

Hi there! I’m trying to figure out my ROI for when I’ve sold out and bought back in, and it’s making my head hurt.

I bought AAPL:

  • 30/05/2019: 1 share at 141.85
  • 26/09/2019: 1 share at 180.53

Then I sold both shares as I was switching from ISA to Basic Account:

  • 10/12/2019: 2 shares sold at 407.79

Then I bought back in in my Basic Account:

  • 10/12/2019: 1 share at 205.49

I then waited a while and picked up some fractionals along the way:

  • 05/06/2020: 0.38256702 at 100.01

Current market value is 420.18

Is there anyone smart who can run me through how they calculate ROI on this?

I’m sure someone will be able to - but my guess is you’ll have to confirm the exact exchange rates you bought and sold for each time you bought and sold, as there will be some fx rates and currency fluctuations in there.

Correct me if I’m wrong but as at right now, on a money in / money out basis, it would look like this:

Total Out = 627.88
Total In = 407.79
Current Value = 420.18

Return = (407.79 + 420.18 - 627.88) / 627.88 = 31.9%

That return, +/- FX on final sale, is not booked yet though…
