What it means
In a typical pyramid, a trader buys an initial position and waits. If the price rises, the trader buys more, usually in smaller amounts than the first purchase, and repeats the process at higher prices.
The shape resembles a pyramid, with the largest position at the bottom and smaller additions on top. The idea is to put more money behind trades that are proving right, rather than adding to trades that are going wrong.
Supporters argue it follows the saying about cutting losses and letting profits run. The average cost rises with each addition, but the position grows while the trend continues.
Pyramiding is often combined with margin, meaning borrowed money from a broker. The rising value of the existing position can allow a trader to borrow more and buy more without adding fresh cash.
This increases leverage, which is the use of borrowed money to boost exposure. The danger is a reversal.
Because the later purchases were made at higher prices, a modest fall can wipe out the gains on the earlier ones, and a sharp fall can leave the trader with losses on a large position. If the trader has borrowed, a margin call (a demand to deposit more money) may force a sale at the worst moment.
Disciplined pyramiders therefore set rules in advance. They decide the size of each addition, the price move needed to trigger it, and a stop-loss level at which the whole position is sold.
Many keep each addition smaller than the one before, so the average cost stays well below the latest price. The word also has other uses.
In real estate, pyramiding means repeatedly using the equity in one property to buy another, building up a portfolio on borrowed money. In both cases, the strategy works well in rising markets and can unwind quickly in falling ones.
In practice
Real-world examples.
Example
A trader buys 100 shares of a technology company at $50. As the price climbs to $56 and then $60, she buys additional blocks of 50 shares each time. By the time the price reaches $64, her profit is $2,000 on a total outlay of $10,800.
Example
A property investor buys a rental flat with a mortgage. After prices rise, she borrows against the increased value to buy a second flat, then a third. When property values fall, the combined debt exceeds the value of the portfolio and she struggles to refinance.
Example
A commodity trader buys futures contracts as the price of wheat rises, using the gains on earlier contracts as margin for new ones. A sudden drop in prices triggers margin calls on the whole position, forcing him to sell at a loss.
Formula
Calculation
Average cost per share = total cost of all purchases / total shares bought
Unrealised profit = (current price - average cost) x total shares
Suppose a trader buys 100 shares at $50, adds 50 shares at $56 and adds another 50 shares at $60. The total cost is 5,000 + 2,800 + 3,000 = $10,800 for 200 shares, so the average cost is 10,800 / 200 = $54. If the price rises to $64, the unrealised profit is (64 - 54) x 200 = $2,000. If the price instead falls back to $50, the position shows a loss of (50 - 54) x 200 = -$800 even though the first purchase was made at exactly $50.Case study
Seen in the real world.
Quarry Hill Partners is an illustrative, fictional small investment partnership that applied a pyramiding approach to a rising shares trend. It bought 1,000 shares at $20, then 500 more at $22 and another 500 at $24, using margin borrowing to fund the later purchases. The average cost was (20,000 + 11,000 + 12,000) / 2,000 = $21.50.
The price peaked at $27, giving an unrealised profit of (27 - 21.50) x 2,000 = $11,000. Then an unexpected announcement dropped the price to $19. The position showed a loss of (19 - 21.50) x 2,000 = -$5,000, and the broker issued a margin call.
The partnership had to sell to meet the call, turning a paper gain into a real loss. The illustrative lesson was that pyramiding requires a firm exit rule, because the position is largest just when the price is most likely to reverse.
Watch out
Common mistakes.
- Adding equal-sized amounts at higher prices, which pushes the average cost up quickly and leaves little room for a pullback.
- Using borrowed money to pyramid without allowing for a margin call if the price reverses.
- Pyramiding without a stop-loss or exit plan decided in advance, so emotions drive the decisions when the trend turns.
Questions
People also ask.
Is pyramiding the same as averaging down?
No, averaging down adds to a losing position at lower prices, while pyramiding adds to a winning position at higher prices.
Is pyramiding legal?
Yes, it is a normal trading technique, although brokers and regulators set margin rules that limit how much borrowing can be used.
Why do traders make later additions smaller?
Smaller additions keep the average cost further below the market price, which gives the position more room to absorb a fall.
