Prior to the mid-1990's, there was a relatively organized flow of information to individual investors. This process had definite flaws. The personal computer and the Internet have made possible massive changes in the ways that individuals invest, and these changes have only just begun to be felt. In the long term, this is probably a good move. However, these same forums also allow totally anonymous individuals to write anything at all about a stock, whether it is relevant, or even true.

Technical analysis is invaluable in understanding how the market has reacted in the past, but it was once very labor-intensive and not well understood. However, the required format is almost impossible to follow unless the reader has a substantial amount of experience working with it. My most immediate concern is with the amount of mis-information that is posted on the various Internet forums, and generally by people who post anonymously. And this warning includes The Napeague Letter itself. Don't ever take my Analyses for granted.
