This research piece from Ross Stevens, Joshua Zwick, and Randolph B. Cohen explores breaking free from the traditional 60/40 portfolio. The authors make two simple, but critical points: first, the bad news: if investors continue to build portfolios as they have traditionally, many will fail to meet their investing goals. Second, the very good news: they believe it is possible for investors to increase the likelihood of meeting their objectives. However, doing so will require adopting a fundamentally new investing mindset. Small tweaks will not be sufficient.
