Is the Market Efficient?

There is a school of thought that says that all information about a stock and it’s value is reflected in the price it trades at, and therefore you should not pick individual stocks, just indexes and passively buy and hold.  That was my impression when I started this project with the assumption that a good stock would be 10% overvalued and a poor stock 10% undervalued.  There are reasons for the differences that I will go into detail about later but I was quite surprised to see, even after a large drop in many stocks that the spread would be more like 80% undervalued to 240% overvalued(as of when I wrote this).

Check out the Company Data Table and look at the stock price % of proved to see the differences.  Now we are not ready to pick stocks yet but it shows that maybe with some more information we can drill down and make a more informed decision.

More on how to use the table and how it was constructed later.
