## Cumulative Loss Accounting

Cumulative loss accounting is the practice of tracking the total, aggregate losses incurred over the life of an investment or across an entire portfolio to determine the net tax position. This method is particularly useful for traders who deal with multiple assets and complex derivative strategies, where individual trades may be profitable or loss-making, but the overall performance must be assessed.

By maintaining a cumulative view, investors can better understand their exposure to tax liabilities and identify opportunities for loss offsets. It involves summing all realized losses and gains to arrive at a net position that informs future trading and tax decisions.

This approach provides a clear picture of the economic reality of the investment activity, moving beyond individual trade results to focus on the overall financial health of the portfolio.
