SI310: The Illusion of Backtests and True Drivers of Price ft. Richard Brennan

SI310: The Illusion of Backtests and True Drivers of Price ft. Richard Brennan

Together with Richard Brennan we address the high level of volatility we have experienced this month and what airplane turbulence can teach us about periods of volatility. We also discuss why backtesting can’t predict future performance and what can be done to achieve achieve more realistic expectations of future risk and returns. We then dive into how investor behaviour drives price movement and how trend followers play a role in this, and why it may still make sense to include highly correlated assets in your trend following portfolio and more.
