Harley Bassman on Why the Big Moves in the Bond Market Are Done

Convexity Defined

Convexity, a term often shrouded in complexity, is essentially about unbalanced leverage in financial markets. Harley Bassman explains that convexity involves non-linear payoffs, where the potential gains and losses are not equal. For instance, positive convexity occurs when you make $2 for every $1 lost, while negative convexity is the opposite 1. This concept is crucial for traders, as it helps in pricing various financial instruments and understanding risk-reward profiles. Bassman notes, "Convexity just means that the payoff is not linear. It's not one to one."

   

Trading Strategies

In trading, convexity plays a pivotal role in strategy formulation. Harley Bassman shares insights on how traders can leverage convexity by adjusting their portfolios to either be short or long on convexity, depending on market conditions 2. He highlights that in the bond market, traders often manipulate three key risks: duration, credit, and convexity, to optimize returns 3. Bassman emphasizes, "You're usually paid more to take longer maturity risk because there's more uncertainty." This strategic manipulation allows traders to navigate complex market environments effectively.
