Your new average purchase price after buying more shares at today's price, and the price you need to break even.
Figures checked: October 2026 · Methodology and sources
Buying more lowers the average, not the risk: it puts more money in the same investment.
When a share or fund you own has fallen, buying more at today's lower price brings down your average purchase price: (shares owned × old average + shares bought × today's price + fees) / all shares.
The lower average means a smaller rise is needed before the whole position is back in profit. It does not make the investment safer: you simply hold more of it.
Only if you would buy the investment today anyway. A falling price alone is not a reason: some never recover.
