Free information and the Efficient Market Hypothesis
by John Schroy filed under Securities, Economic Theory, Technology
In some capital markets, such as the United States, there is a vast amount of free factual information about stocks and bonds available on the Internet.
According to the Efficient Market Hypothesis, this flood of free information should result in an “efficient market” in which prices reflect the “intrinsic value” of securities.
However, the Crash of 2008 demonstrated that although much information was indeed “free”, the market was far from “efficient”.
The dominant aspect of the market in Q4 2008 was that no one seemed to know what securities were really worth — despite all this “free information”.

Free information has a cost, if not a price
In order to investigate the world of free information, I engaged in an experiment. I chose the stock NRO (Neuberger Berman Real Estate Income Fund, Inc.) to do some research based on “free information”.

This stock is listed on the American Stock Exchange and has free commercial information posted on various sites:
- Yahoo Finance
- ETF Connect (Nuveen Investments)
- Closed end fund association (Lipper-Reuters)
- Bloomberg
The stock was thinly traded and usually had no analyst reports available.
On March 9, 2009, the stock was trading at $0.84 and had an indicated cash yield of 54.7%.
The stock had been issued in 2003 at $15. It was an closed-end fund investing in REITs and managed by Neuberger Berman, an investment management firm that had been involved in the Lehman Brothers bankruptcy.

Questions to be answered
The questions I wanted to answer about NRO were as follows:
- Could the current yield be maintained?
- Was the investment manager acting prudently?
- What had caused the drastic loss of value? Had past errors been corrected?
- Was the stock a reasonable investment?
I won’t say what my conclusions were, but the facts that I was able to find from free sources on the Internet are posted on Capital Market Wiki.
Most of the required information was found in SEC files, the company website, legal sites, and miscellaneous sites found through Google.
It took me about 75 hours to research the facts indicated above, between February 27 and March 6, 2009.
You can compare these facts with the base information that was immediately available on Yahoo and the other sources indicated and judge for yourself the value of this research.
Between March 9, 2009 and April 20, 2009, the price of NRO increased and the stock returned (including two cash dividends), about 96%.
The cost of the “free” information, for me, in this case, was about 75 hours of work.
