Lower average cost can coexist with a larger portfolio loss
Assume total funds of 100: invest 50 in an asset priced at 100 and retain cash of 50, holding 0.5 units. At a price of 60, the asset is worth 30 and total wealth is 80 including cash of 50. Investing all remaining cash of 50 gives about 1.3333 units and an average cost of 75. If the price subsequently rebounds 30% to 78, the additional-purchase plan is worth 104; retaining cash leaves 39 plus 50, totaling 89. If the price instead falls further to 30, the additional-purchase plan is worth 40, while cash retention leaves 15 plus 50, totaling 65. A lower average cost comes with increased downside exposure. Separately, an entirely invested asset falling 40% and then gaining 30% takes an initial value of 100 to just 78, not breakeven; recovery requires about a 66.67% gain.
Check for yourself
- Beyond average cost after adding, have total wealth, remaining cash and maximum allocation been calculated?
- Have delayed recovery, further declines and liquidity needs been compared along the same price paths?
Limits of application
Funds, prices, quantities and both paths are hypothetical, not rebound-probability estimates or recommendations to add to a particular security. Fractional units are allowed; fees, taxes, interest, exchange rates, credit and leverage are excluded. Real securities may never recover after permanent impairment or delisting, while holding cash also has opportunity costs.
- What to look for
- Examine scenarios separating rebound strength from trend recovery and the rationale for staged purchases.
- Why it matters
- Assess trend-confirmation criteria separately from position size. Compare how additional purchases change not just average cost but portfolio downside exposure and available cash.
Timeline
4 segmentsThe closing presents security selection and staged buying and selling with cash reserves as the speaker’s preferred approach for ordinary investors. Buying more after losses can lower average cost but increases risky exposure, so it is neither universally superior to exiting nor supported by a guaranteed rebound. Compare recovery assumptions, maximum allocation, further downside and liquidity needs; leaving a loss unrealized does not eliminate the economic loss.
