It is not necessary to report monthly/quarterly gains or losses, or to detail reinvested dividends, fees, etc. for investment accounts. As long as the funds stayed within the account or portfolio, even if different stocks were bought and sold, just report value changes as a net gain (Asset Appreciation) or net loss (Asset Depreciation) using the statement closest to the period end date of your report. If money was distributed from the investment, report that as a transfer from the investment account to the receiving account (or as an expense if it did not go to another account). If money was added to the investment from another account, report that as a transfer from that account to the investment account (or as income if it came from an outside source). If dividends are issued and deposited into a financial account other than that investment account, enter those as income transactions (Investment – Dividends) in that other account.
