Post Modern Security Analysis

Security Analysis is the study of facts about negotiable instruments for the purpose of determining whether a particular instrument is appropriate for a specific investor at a particular time and the intrinsic value of the security compared to its market price, if any.

In the 21st century, with a flood of open source information and increasingly complex, global markets, new approaches are necessary.
