I remember the first time I walked into Henry Blodget's new startup, Business Insider, back in 2009. Twelve fresh-faced kids were crammed into a room about the size of my bedroom, pounding away on laptops, creating a new destination website. He took me over to a corner; we sat down in front of a few cameras; and he began shooting question after question at me, later turning the session into a series of interviews.

You walk into his office today and it's still packed wall-to-wall with fresh-faced kids (the older I get the younger they look), but the offices are much larger, and it seemed to me last time that there had to be at least 150 people in them. But the interviews are still quick-paced, even if they're now conducted in a special room, with upgraded equipment.

One of the things Business Insider is noted for is compelling headlines. They republish much of the work from Mauldin Economics, but they often come up with more interesting headlines for our content than we do. And they still produce a lot of original material as well.

This week's Outside the Box is a brief note from Henry himself, with the snappy title “Market history is calling, and it's saying stock performance will be crappy for another ~10 years.” Beyond the compelling headline is a look back at historical market performance and market cycles, with almost a dozen charts to illustrate Henry's thesis. It's a quick read, but investors should pay attention to his main premise: if you're looking for returns that are north of zero, you're going to have to be a better-than-average investor.

As an aside, I want to pass along my congratulations to Henry on the rather outsized offer (in the multiple nine figures) he has received from a German publisher for his business. I've always admired his determination and focus, and I enjoy watching another businessman prosper.

Now here's a good one for you. I'm sitting in my dentist's chair this morning, he's checking on the laser-evisceration of my gums he performed last week, and he says, “You know, most older people have the opposite problem from you – they have too little in the way of gums, not too much. And that's where we got the old saying ‘long in the tooth.'” So there.
