## Weighted Average Cost Method

The weighted average cost method is an accounting technique used to determine the cost basis of an asset by calculating the average price paid for all units held. This method is often preferred for its simplicity when dealing with large volumes of identical assets acquired at different times and prices.

Instead of tracking each individual purchase, the investor sums the total cost of all units and divides by the total number of units held. This creates a single average cost basis that is applied to all subsequent sales.

In volatile markets, this method can smooth out the impact of price fluctuations on the reported cost basis. However, it may not be the most tax-efficient method compared to specific identification, which allows the sale of high-cost units first.

Taxpayers must generally choose a method and apply it consistently across their portfolio. This method provides a reliable and defensible way to report gains and losses.
