My understanding of Shareholder Equity / Retain Earnings / Company Value changes over time is:
Last Shareholder Equity +/- after tax profit / loss = New Shareholder Equity
I have been observing my results, and my results don't follow this pattern.
In the long run: Yes, roughly speaking
But from week to week: No
It could be that there may be some timing issue of how some transactions are applied that is throwing off the results from week to week....
