Summary

In this interview, Didier Darcet and Richard Détente discuss the concept of momentum in financial markets, distinguishing it from technical analysis. They explain that while price movements are largely random, there is a statistical tendency for markets to exhibit momentum in risk: once a market starts declining, the probability of further declines increases. This is linked to the notion of drawdown, which represents the cumulative loss from a peak to a trough. They emphasize that the true risk is not daily volatility but the potential for large drawdowns, which can be psychologically devastating and lead to panic selling. To mitigate this, they propose a simple strategy: using a reference point (e.g., the previous year’s closing price) and selling when the market falls below it, then re-entering when it rises above. This approach, tested over 60 years on the MSCI World, yields slightly lower returns than buy-and-hold but with significantly reduced maximum drawdown (7% vs. 50%). They also discuss the concept of ‘memory of shocks’ and the use of moving averages. The conversation concludes with a discussion of the ‘Grand Angle’ strategy and the importance of risk management in investing.
