Averaging Down
Averaging down means buying more of an asset below the price paid earlier, reducing the average purchase price. Taleb’s Carlos story shows how that can increase exposure to a mistaken belief that a decline must reverse.
THE IDEA
When the market started falling, he accumulated more Russian bonds, at an average of around $52. That was Carlos’ trait, average down. The problems, he deemed, had nothing to do with Russia, and it was not some New Jersey fund run by some mad scientist that was going to decide the fate of Russia. “Read my lips: It’s a li-qui-dation!” he yelled at those who questioned his buying.
By the end of June, his trading revenues for 1998 had dropped from up $60 million to up $20 million. That made him angry. But he calculated that should the market rise back to the pre–New Jersey sell-off, then he would be up $100 million. That was unavoidable, he asserted. These bonds, he said, would never, ever trade below $48. He was risking so little, to possibly make so much.
Then came July. The market dropped a bit more. The benchmark Russian bond was now at $43. His positions were underwater, but he increased his stakes. By now he was down $30 million for the year. His bosses were starting to become nervous, but he kept telling them that, after all, Russia would not go under. He repeated the cliché that it was too big to fail. He estimated that bailing them out would cost so little and would benefit the world economy so much that it did not make sense to liquidate his inventory now. “This is the time to buy, not to sell,” he said repeatedly. “These bonds are trading very close to their possible default value.” In other words, should Russia go into default, and run out of dollars to pay the interest on its debt, these bonds would hardly budge. Where did he get this idea? From discussions with other traders and emerging-market economists (or trader-economist hybrids). Carlos put about half his net worth, then $5 million, in the Russia Principal Bond. “I will retire on these profits,” he told the stockbroker who executed the trade.
When to use it
An investor buys more shares of a stock as its price falls, expecting a rebound based on past performance rather than new information.
A trader increases exposure to a cryptocurrency during a market crash, convinced the downturn is exaggerated by panic selling.
A real estate developer acquires additional properties in a declining market, assuming the downturn is short-lived and prices will revert to previous highs.
FROM THEORY TO EVERYDAY LIFE
In practice
Carlos and Russian Bonds
Carlos, a trader, averaged down on Russian bonds as the market fell. He bought additional bonds as the price fell from $52 to $43, believing the decline was a temporary liquidation. He ignored warnings and invested half his net worth, expecting the market to recover. Instead, the market continued to fall, and his losses mounted.
A MOMENT TO REFLECT
Put it to work.
Have you ever averaged down on an investment or decision? What cognitive biases might have influenced you?
How can you distinguish between a temporary dip and a fundamental decline when considering averaging down?
What mental checks could you implement to avoid the overconfidence shown by Carlos in this story?
