Whenever I see a forecast written out to two decimal places, I cannot help but wonder if there is a misunderstanding of the limitations of the data, and an illusion of precision.

In social media, people cannot build big followings organically unless what they are putting out to the world has value.

Yearly data put the rest of the noise into perspective. Most of the weekly or monthly random up-and-down movements get smoothed out. Ultimately, this is where long-term investors should be focused.

I see it as a responsibility of mine to teach others.

I see no reason to have my shirts ironed. It's irrational.

The data strongly suggest that very good years in the U.S. stock market are followed by more good years.
