Frequently Asked Questions
What does averaging down mean in investing?
Averaging down means buying additional shares of a stock you already own at a lower price than your original purchase. This lowers your average cost per share, which reduces the price the stock needs to recover to before your total position is profitable. It is a common strategy when an investor still believes in the long-term thesis but wants to take advantage of a temporary price drop.
How do you calculate the average cost after adding to a position?
Average cost equals total capital invested divided by total shares held. If you bought 100 shares at $50 ($5,000) and then add 100 more at $30 ($3,000), you have 200 shares and $8,000 invested, so your new average cost basis is $40 per share. The calculator does this automatically for any number of additional purchases.
When should you average down on a stock?
Averaging down makes sense only when the fundamental thesis for owning the stock is unchanged and the price drop is due to market noise rather than a broken business model. If the reason you bought the stock is still intact and the position size is still within your risk limits, lowering your cost basis can speed up recovery when the stock eventually rebounds.
What are the risks of averaging down?
The biggest risk is throwing good money after bad. If the stock keeps falling, each additional purchase deepens your loss and concentrates portfolio risk in one position. Never average down without a stop loss on the combined position, and never increase position size beyond what your risk rules allow for a single trade or single stock.
Is averaging down a good strategy?
Averaging down works well for long-term investors buying quality companies at a discount and works poorly for short-term traders riding a broken setup down. The key is discipline: predefine how many times and at what prices you will add, and stop if the thesis breaks. Many pro traders instead use the opposite approach, adding to winners, not losers.
