1. Why record both quantity and purchase price for each transaction?
Show answer and why
Answer: They determine the amounts contributing to the combined purchase cost.
Why: A simple average of prices ignores different share quantities.
2. Why check whether fees are included?
Show answer and why
Answer: They can change the total cost measure.
Why: A displayed average and your complete transaction cost may use different definitions.
3. Does a lower average purchase price guarantee a gain?
Show answer and why
Answer: No. The later sale value and costs still matter.
Why: A purchase-cost measure does not predict the future market price.
Key takeaways
- Use both share quantity and purchase price when combining purchase costs.
- Check whether the displayed average includes transaction fees.
- A lower average purchase price does not guarantee a gain on sale.
