The process of purchasing additional shares of a security after its price has declined from the initial purchase price, thereby lowering the average cost per share, is a common investment strategy. For example, if an investor buys 100 shares at $50 and the price drops to $25, buying another 100 shares at $25 brings the average cost down to $37.50. This technique can be facilitated by online tools that automatically calculate the adjusted cost basis after additional purchases.
Lowering the average cost basis through subsequent purchases offers several potential advantages. It can reduce the overall loss if the security recovers and potentially accelerate profitability. Historically, this approach has been favored by value investors seeking opportunities in temporarily depressed markets. However, it is essential to acknowledge the inherent risks. A declining price could signal underlying fundamental issues with the security, and further investment could exacerbate losses if the price continues to fall. Thorough research and risk assessment are crucial before employing this strategy.
