Welcome back to work after a long, hopefully relaxing weekend.
Friends in the industry are collectively wondering when their friends, family, and clients will take a few (highly concentrated) chips off the table.
Although continuing to hold a concentrated stock might seem like a status-quo stance, it is, in fact, one of the most risky investment strategies an investor could pursue, and it is especially problematic for those wealth creators who seek to become guardians of wealth for themselves and their families… Bessembinder (2018) shows that, during the 1926–2016 period, for all the 25,967 common stocks in the Center for Research in Securities Prices (CRSP) database, by far the most frequent one-decade buy-and-hold return is -100%.
But, of course, a certain slice of humanity loves concentrated risk, and there’s a huge counternarrative…

For the third post in a row, I will copy/paste Morgan Stanley’s “eyeroll” table of reasons people continue holding concentrated positions. We should, apparently, include “Hindsight” as another reason.
Relatedly, Meg makes an interesting point by arguing that holding “the one” stock is kind of a male thing.
