Last week, I wrote about an experience I had with a broker who took offense at the use of the term “broker” in a talk I gave to a group of investors. I found that odd because he is employed by a large brokerage firm. So I asked what he wanted to be called, and…

Anna Cieslak and Pavol Povala—authors of the paper “Expected Returns in Treasury Bonds,” which was published in the September 2015 issue of The Review of Financial Studies—examined the time variation in the risk premium that investors require for holding Treasury bonds.

In personal finance, almost all of the advice we come across seems to focus on playing defense. We’re always looking for ways to build bigger and better walls to protect ourselves from bad behavior: Cut up the credit cards. Pay only with cash. Stick to a budget. Hide the passwords.

Every January, I put together a list of predictions that financial “gurus” have made for the upcoming year, especially the ones that gain consensus as “sure things.” I then keep track of whether these “sure thing” forecasts actually came to pass, through a series of periodic updates. The inevitable turn of the calendar into October…
My book, “Investment Mistakes Even Smart Investors Make and How to Avoid Them,” covered 77 common errors I believe investors commit all too often.
