Averaging Down
Buying more of a stock after it has fallen to lower your average purchase price — helpful if it rebounds, but it enlarges losses if the decline continues.
Averaging down = buying more of a holding after it declines, lowering the average purchase price
If the reason for the drop is temporary and the company is solid, averaging down lowers the average price and works in your favor on a recovery.
In plain terms
Averaging down means buying more of a stock after it falls, which lowers your average purchase price. If you bought one share at $100 and it drops to $60, buying one more share brings your average price to $80. Then the price only has to get back to $80 for you to break even.
If it rebounds, you reach a gain sooner; but if it falls further, the loss grows twice as fast. That is why it is often described as "medicine when used well, poison when used badly."
What it tells you
Averaging down is a choice about whether you see a decline as an opportunity or as a risk. If the company is still doing fine and the price fell because of the market, it may be an opportunity; but if the price is falling because the company itself has deteriorated, it only enlarges the loss.
So the outcome of averaging down depends on "why it fell." A case where the fundamentals (earnings and finances) are unchanged and only the price dropped plays out differently from a case where the business itself has turned down.
Formula
Averaging down = buying more of a holding after it declines, lowering the average purchase price Example: 1 share at 100 + 1 share at 60 → average price of 80
What high or low means
If the reason for the drop is temporary and the company is solid, averaging down lowers the average price and works in your favor on a recovery. Conversely, if the company is deteriorating structurally, averaging down becomes a trap that enlarges the loss.
Repeatedly averaging down on one stock makes that position too large a share of the portfolio, breaking diversification and concentrating risk in one place.
The biggest risk of averaging down is that "there is a reason for the fall." If you average down on a stock that is dropping because the company has deteriorated, the average price falls but the loss amount keeps growing. Buying more simply because the price is lower is risky. (This is a conceptual explanation, not a suggestion about any particular trade.)
If averaging down makes one holding an excessive share of the portfolio, the whole portfolio wobbles when that stock goes wrong. The more you buy, the thinner your diversification becomes.
The psychological comfort of "having lowered my average price" can itself become a trap that keeps you holding on to a poor stock.
