What is a realistic return on value investing?

Do not think you should omit any data as it is real profit/Lost. the super high value is due to solid performance within a short period.

Yes, mathematically the geometric calculation is not incorrect even if hard for the brain to wrap around it.

If you can consistently do this for rest of year, it is this super value. The reality is, we all can't. The problem can be easily overcome.

If is performance within a year (YTD), what you should do is to use end date 31 dec in your balance unsold stocks.

Yes, if want to find a way to include for YTD measurement, 1 way is to decompress end date of very short period transaction to year end.

If is multi-years as continuous of your investment since day 1, is not a problem either because over the course of years all your trade recorded will spreaded out, sudden spike due to profit within a short period for a stock is kind of "amortized". If you still see super high value, that's mean your performance is really solid which is unlikely and likely you have computed wrongly.

True, the impact of the very high % of the very short period return will get diluted by longer period returns, with dilution dependent on relative position sizes.

I like your determination and the way you think out of the box.
