Averaging Down
Buying more of a position that's already losing to pull the average cost down, a different move from pyramiding, which adds to a position that's already winning.
Play the decline, decide when to add
A position opens automatically at bar one. Press play and watch a real declining price path unfold. Click "Average down" at any point to buy another equal-dollar lot at the current price, up to six times. The strip below the chart is the required bounce back to breakeven, recalculated after every bar and every add.
Gold line = price · dashed line = average cost · strip below = required bounce to breakeven, bar by bar
How it works
- It's a second, third, or fourth buy at a lower price than the first. Each add is sized the same in dollar terms here, so a lower price buys more shares, which is what pulls the blended average cost down.
- The required bounce is measured from the current price to the average cost, not the original entry. Right after an add, that number usually drops, because the average cost moved closer to where price is now. That's the entire appeal of the tactic in the moment it's used.
- If the decline keeps going after the add, the required bounce grows right back. The average cost only improved relative to the price at the moment of the add. Price falling further afterward pushes the gap back open, and the strip chart below the price line tracks that number over time, not only at the instant of the trade.
- Capital at risk only goes one direction: up. Every add is more money committed to a position that is, by definition, still underwater when the add happens. Nothing about the mechanics caps how many times that can happen except a rule the trader sets themselves.
Where this breaks
There's no mechanical rule for when to stop adding
Averaging down has no built-in exit for the tactic itself, only for the position. A stock that's down 20% and gets one add can keep falling another 20%, and another, and each time the same logic that justified the last add justifies the next one: the average cost will look even better after this one. Run the simulation above enough times and some price paths never turn back at all before the path ends, which is the same thing that happens to a real position that averages down into a stock that's re-rating lower for a reason instead of dipping temporarily.
