It is appropriate and perhaps entirely ironic that the subject of this week’s Dividend Cafe comes in a week where we have seen some of the most bizarre, insane, and silly market activity, ever, and that this bizarre, insane, and silly activity is accompanied by totally incoherent commentary from various pundits, politicians, and “pros.”

Whoever said investing was all math and science is an idiot.

But the drama of this week’s market, and even the circumstances around the big headline story of the week (which has actually morphed into a multi-faceted story), really do serve as a reinforcement of the major principles, beliefs, and applications I want to highlight in this week’s commentary. I began writing this Dividend Cafe last weekend, and had conceptualized my thesis well before the drama hit the tape into the week. And I haven’t altered that thesis or even the way I unpack it at all. To the extent some of this week’s Dividend Cafe connects dots with other news stories, great. But my purpose in this week’s commentary is not to make sense of a four-day story, but a four-decade story.

And I really hope it will help you in your journey and understanding as an investor.

I have long believed that all professional investors are irreversibly shaped by the era in which they grew up as an investor. This is more true of the lessons learned in that era that proved to be negative lessons than positive ones. Put differently, the major events that damage us in our formative years teach lessons that don’t go away easily.

I want to do a little history this week, talk a little investment biography, and ultimately, offer some lessons about my outlook on the present investing era that ought to transcend anything you will find in a chat room, on social media, or in the madness of the moment.

It’s a low bar.
