GOOGLEFINANCE (Never breaks)What is averaging down in stock investing?
Averaging down is the practice of buying more shares of an asset after its market price has fallen below your original purchase price. By adding cheaper shares, your weighted average purchase price drops closer to the current market price.
The primary psychological and financial advantage is that it significantly lowers the recovery hurdle. For example, if you buy a stock at $100 and it falls to $50, you need a massive +100% gain just to get back to even. But if you double your position at $50, your average cost drops to $75, meaning you only need a +50% gain to break even.
The mathematical formula explained
The weighted average cost basis is calculated using the following arithmetic formula:
- S₁ = Number of initial shares owned
- P₁ = Initial price paid per share
- S₂ = Number of new shares bought on the dip
- P₂ = Purchase price of the new shares
When should you average down — and when should you avoid it?
Averaging down is not universally sound; its effectiveness depends entirely on the fundamental health of the underlying asset:
✓ Good times to average down:
- Broad market-index ETFs (e.g., S&P 500, VOO, SCHD) during market corrections.
- Profitable companies with strong balance sheets and intact moats.
- High-quality dividend aristocrats whose cash flow easily covers their dividend.
✕ Dangerous times (The “Falling Knife” trap):
- Unprofitable growth companies running out of cash.
- Stocks experiencing structural decline, fraud, or loss of competitive edge.
- When the additional purchase exceeds your overall portfolio risk tolerance.
