About Benjamin Graham
Role: Father of Value Investing and Security Analysis
Core Belief: An investment operation is one which, upon thorough analysis, promises safety of principal and an adequate return. Operations not meeting these requirements are speculative.
Worldview: Markets are driven by psychology in the short term but tend toward rational valuation over time. The intelligent investor uses market fluctuations rather than being guided by them.
