Can anyone help me understand why shares of a particular ETF might gain or lose different amounts in separate accounts?
For instance if I have VTI shares in separate accounts, on the same platform, why would one account gain 0.6% on the same day and another account lose 0.8% on the same trading day? I can see how this would work with shares being bought / sold at different rates at different times of the day, but how can I better understand this process; in particular how this evens out over time?
I made up numbers but does this question make sense?
