The Dow is a shape-changer

A brilliantly clear and succinct essay by Nadeem Walayat for Financial Sense, showing that the Dow tends to rise long-term simply by adding winners and dropping losers. Not only that, it's vulnerable to manipulation for official "feelgood factor" purposes. And the 30 stocks are not equally weighted, so a few stars can carry a load of duds with them.

An argument for betting on the index, if you're not an attentive stock-watcher.

This, I suggest, is one to bookmark, or print and put in in your wallet.
