Most of the World's Companies Are Duds

This article by Vildana Hajric for Bloomberg may be of interest to subscribes. Here is a section:  

Investors have heard this refrain before, that just a scant few pull the pack. And it’s easy to see their outsize influence: Microsoft, Apple, and Facebook Inc. account for more than 20% of the S&P 500’s returns this year. That number is even starker for the tech-heavy Nasdaq 100, for instance, where those four companies account for about 50% of gains.

But Bessembinder and his team, including two co-authors from Hong Kong Polytechnic University and Goeun Choi of Arizona State, are among the first to look at the phenomenon long-term. The best-performing 306 firms accounted for about three-quarters of global net wealth creation during the 28-year period of the study, they found. Just 811 companies could be framed as accounting for all of it.

Their findings echo Bessembinder’s previous work. In looking at nearly nine decades of U.S. stock and bond performance, he found that out of 26,000 stocks, about 58% underperform Treasury bills in their lifespan.

Eoin Treacy's view

There are two lessons from this data. The first is it has been hard to outperform bonds during one of the greatest bull markets in history. With forty years of history that is a lot of empirical data to base conclusions on. However, it also assumes the status quo remains intact indefinitely.
