Why Average Down with Discipline?
Averaging down can significantly lower your break-even hurdle during market pullbacks. However, always ensure the underlying company fundamentals remain intact to avoid dollar-cost averaging into a value trap.
Frequently asked questions
How is weighted average share price calculated?
Weighted average share price is calculated by multiplying each buy lot's share quantity by its purchase price, summing all purchase amounts together, and dividing by total shares owned.
What is Dollar-Cost Averaging (DCA)?
DCA is an investment strategy where you divide your total capital into periodic purchases over time, buying more shares when prices drop and fewer shares when prices rise, lowering your average cost basis.
What is the difference between FIFO and Average Cost basis?
FIFO (First-In, First-Out) assumes the earliest purchased shares are sold first, which affects tax reporting. Average cost basis takes the blended price across all lots, commonly used for mutual funds and general portfolio tracking.
Can I add more than 3 buy lots?
Yes. You can add as many buy tranches as needed using the '+ Add Buy Lot' button to model complex accumulation over time.
