Why Calculate Your Average Stock Cost?

When you buy shares of the same stock at different prices and times, your average cost isn't just a simple mean. It's a weighted average that reflects your true financial position. Knowing this number is crucial for:

  • Informed Decision-Making: Decide whether to average down on a dip or take profits with confidence.
  • Accurate Profit & Loss Tracking: Understand your real break-even point to accurately assess your portfolio's performance.
  • Strategic Planning: Effectively manage your positions and plan future trades without guesswork.
