The Horse in Motion

By Ben Hunt | April 3, 2017 | 0 Comments

Many of the gaps in our knowledge are the result of our insistence on accepting our priors and using technology to answer questions we see as new. But what if we could develop techniques to challenge those priors with new questions?

Peter Griffin buys a tank.

I am Spartacus!

Oh, we all use index funds. ETFs. We all avoid the evils of acting trading, sure. But in the end, we are all active managers, friends. Yes, you, too.

Mailbag: Life in Trumpland

By Ben Hunt | March 6, 2017 | 0 Comments

The best part about this job, other than being recognized in random bars by 50-year old financial advisors who are always good to buy me a drink (hey, you take your celebrity where you can), is the correspondence with readers. I began writing Epsilon Theory 3+ years ago from a pretty dark place, and it’s …

I’m Not Predicting, I’m Observing

By Ben Hunt | March 2, 2017 | 0 Comments

George Soros has a great line, one that I’ve stolen many times: “I’m not predicting. I’m observing.” We really don’t have a crystal ball, and it really is a dumb idea to pretend that we do. But what’s not dumb is to keep your eyes and ears open, observing both what the world is telling you (playing the cards) and what other market participants are telling you (playing the players), and reacting accordingly. That’s the heart of tactical investing.

The Evolution of Competition

By Ben Hunt | February 7, 2017 | 0 Comments

Over the past few weeks, I’ve had a fight with my wife and email spats with two of my best and oldest friends. In each case, I didn’t recognize that we weren’t really talking about what I thought we were talking about, and by the time I did recognize the real issues, I was already too far down the path of combative Ben to care.

American Hustle

By Ben Hunt | November 17, 2016 | 0 Comments

There are three questions I’d like to answer in this Epsilon Theory note: what did the Narrative Machine tell us about the market immediately before and immediately after the November 8 election, what am I preparing for now as an investor, and what am I preparing for now as a citizen? I’m giddy about the first, quietly confident about the second, and pretty darn depressed about the third. Could be worse, I suppose.

You Had One Job

By Ben Hunt | November 3, 2016 | 0 Comments

Every dog needs a job, and every investment does, too. No single dog can be all things to all people, and neither can a single investment. Nor can any pack of dogs accomplish anything and everything you like. The biggest mistake people make when they get a dog is trying to make the dog fit into the life they wish they led, rather than the life they actually lead.

I want to be a patriot again. I want to be a fundamental investor again. It won’t ever be exactly like it was before, but that’s okay. A renewed faith can be a stronger faith. It just won’t be a blind faith. It has to be a faith based on my own labor and my own time, a non-alienated patriotism and a non-alienated investment strategy. It has to be a political participation and a market participation based on who we are, not who we are paid to be.

Virtue Signaling, or … Why Clinton is in Trouble

By Ben Hunt | September 29, 2016 | 1 Comment

Don’t get me wrong. I’m thoroughly despondent about the calcification, mendacity, and venal corruption that I think four years of Clinton™ will impose. Trump, on the other hand … I think he breaks us. Maybe he already has. He breaks us because he transforms every game we play as a country — from our domestic social games to our international security games — from a Coordination Game to a Competition Game.
