Surprisingly, Benjamin Graham, the acknowledged "Father of Value Investing," considered his most important work to be the invention of the Commodity Reserve Currency Plan during the 1930s and 1940s. Previous studies of the Plan have overlooked the fact that, of its three main components (buffer stocks, price stability, and currency backing), Graham regarded the first as the most important and the other two as "secondary" or "subsidiary." By focusing on the buffer-stock aspect, we demonstrate, first, the breadth and depth of Graham's overall conception in terms of both micro- and macroeconomics, and, second, the considerable overlap with John Maynard Keynes's ideas developed around the same time, which are manifested particularly in their common conclusion that the inefficiency of commodity markets could be rectified only by government intervention. We also comment on Perry Mehrling's assessment of Graham as "not any kind of economist at all" (JHET2011).

In 1924, Edgar Lawrence Smith published a monograph presenting evidence aimed at overturning the conventional view that equities were speculative and bonds were the only long-term investments. This was immediately so successful that such eminent commentators as Irving Fisher and Benjamin Graham agreed that the monograph had had a material impact on market psychology, playing an instrumental role in the Great Crash. In this article, we examine Smith's approach in detail, arguing that he made significant, enduring contributions to finance theory, empirical finance, and portfolio management practice. He was influential in creating the "cult of the equity," laid the foundations for the equity risk premium, and introduced a probability-based risk metric and equally weighted portfolios. His influence is felt nowadays not only in the methodology employed in empirical work but also in major aspects of the conventional approach to portfolio management.
