David Blanchett: Regret Optimized Portfolios, and Optimal Retirement Income (EP.254)
The Rational Reminder Podcast
The Effect of Optimizing Over Regret on Risk Aversion
It's hard enough to do a mean variance optimization because we can't predict the future. And this would be even harder, I can only imagine, to truly optimize XAnnie. How does the effect of optimizing over regret change depending on risk aversion? So it has different effects, right? It could actually increase your expected return based upon your assumptions around regretted assets. But by definition, risk is going to increase because you're allocating more of your wealth to assets that have high volatility.
There are many different objective functions you can use when building optimal portfolios. The majority of these approaches define risk from the perspective of variability or bad outcomes, but positive returns could be viewed as “risky” for those that don’t experience them, which is another way of saying that people experience regret (or FOMO, for our trendier listeners). Today, we are joined by David Blanchett, a return guest and the Managing Director and Head of Retirement Research for PGIM DC Solutions, the global investment management arm of Prudential Financial. He is also an Adjunct Professor of Wealth Management at The American College of Financial Services and a Research Fellow for the Alliance for Lifetime Income. David returns to the podcast for an articulate discussion about regret in portfolio construction, what drives it, and how financial advisors can cater to it. We then delve into how David is redefining optimal retirement income strategies, looking at retirement tools, retirement planning, compensation models in the industry, risk exposures, and portfolios. We also get a high-level overview of some of the fascinating work that David has done on home-country bias, plus so much more. For highly technical content presented in an accessible and practical way by one of the brightest minds in retirement planning, be sure to tune in today!
