Realized gain
What is Realized gain?
A realized gain arises when an asset is sold, redeemed, exchanged, or otherwise disposed of for value above its relevant cost basis.
Broker and portfolio records can disagree when assets move between institutions or corporate actions alter basis. Reconciliation should preserve original acquisition history, lot method, fees, elections, and source documents. Missing basis must remain flagged rather than defaulting to zero or current market value without a disclosed assumption.
Realization dashboards should also distinguish decisions initiated by the investor from tender offers, maturities, fund distributions, corporate reorganizations, option events, and forced liquidations.
Realization event
A sale is the clearest example, but tender offers, fund redemptions, maturities, option exercises, mergers, distributions, and transfers can create or avoid realization under specific rules. The trade date, settlement date, legal disposal date, and payment date may differ. Tax and accounting frameworks determine which date and event controls.
Calculation
Net proceeds are compared with the basis of the disposed lot after allowable adjustments. Partial sales require a lot-selection method such as specific identification, first-in-first-out, or average cost where permitted. Currency movement can create a reporting-currency gain even when the local asset price is unchanged, with tax treatment depending on law.
Realized does not mean recognized
Some realized gains are deferred, rolled over, exempt, or offset, while others are recognized despite no cash being received. Realization is therefore an economic and transaction concept, and recognition is a tax-law conclusion. Portfolio software should avoid labeling every positive disposal amount as current taxable income.
Performance interpretation
Selling a winner does not create investment return at the sale date if prior performance already included its unrealized appreciation. It converts market value into cash and changes tax status. Adding realized gain to total return can double count. Attribution should instead show contribution through time, disposal proceeds, taxes, costs, and changed exposure.
Practical management
Review embedded gains before rebalancing, withdrawals, charitable transfers, or manager transitions. Coordinate sales with loss carryforwards, holding periods, income, and risk. Tax should influence implementation without overriding mandate and diversification. Preserve lot-level confirmations and reconcile realized reports to cash and position changes before using them in filings.
