Questions people ask

What is averaging down?

Buying more of a holding after its price has fallen, which lowers your average cost per share. It reduces the price at which you break even. It does not make the original decision correct, and it increases your exposure to a position that is already losing.

When does averaging down make sense?

When the price fell but the reason you bought did not change — a broad market decline, a sector rotation, a temporary problem you have actually examined. When earnings, competitive position or governance have deteriorated, adding is throwing good money after bad.

How do I calculate my average price?

Total amount invested divided by total shares held. Not the average of the prices you paid — that ignores how many shares each purchase bought, and it will flatter you.

Should I average down on a stock or an index fund?

Adding to a broad index fund on a decline is close to what a SIP does automatically, and the index cannot go to zero. A single stock can, and about half of them underperform the index over long periods. The same action carries very different risk depending on what you are buying.
