Frequently Asked Questions — Average Price

Average down means buying more shares of a stock after its price has fallen. This lowers your overall average buy price, so you need a smaller price recovery to break even or profit.

Multiply each purchase price by the number of lots bought, sum all those values, then divide by the total lots. This calculator does that automatically — just enter each transaction.

Average down means buying more as the price falls (lowering your average cost). Average up means buying more as the price rises (raising your average cost). Both are valid strategies depending on your conviction and risk tolerance.

Not always. Averaging down works well for fundamentally strong stocks in a temporary dip. But for stocks declining due to deteriorating business fundamentals, averaging down can increase your losses significantly.

There's no rule limiting the number of times you can average. However, the more you average, the larger your total position and risk. Many investors set a maximum allocation per stock to prevent over-exposure.

On the Indonesia Stock Exchange (IDX), one lot equals 100 shares. So if a stock is priced at Rp 1,000, one lot costs Rp 100,000 (plus fees).

This depends on your analysis. If the business is still strong and the dip is temporary, averaging can be rewarding. If the fundamentals have changed, cutting losses early often preserves more capital than holding and averaging.
