We try to get Dr. David Blanchett, Morningstar’s Head of Retirement Research, to commit to settling an important debate once and for all about target-date funds—do investors need to be “all in” in their allocations in order for TDFs to work properly, or can some assets be held away.

We also take a close look at target-date strategies amid the volatility of 2020 and look to what lies ahead in 2021. Finally, Blanchett covers important trends in target-date adoption and how firms are adapting to meet participant preferences.
