Why doesn't Graham consider gold as an investment?
During Graham's career, gold and currency were the same thing because of the gold standard. Graham did not advise investing in currencies, only in bonds and stocks, the latter only for intelligent speculation. Graham died a couple of years after Nixon closed the gold window, ending the gold standard.  Gold may be thought of as a currency even today, as endowments and other investors use it as a store of value or for diversification of risks. However, currency or commodities investing does not seem Graham-like. How could you reliably estimate intrinsic value of a currency or commodity, so that you can have a Graham-like margin of safety after subtracting the intrinsic value from the market value?  Saying that gold is "clearly underpriced in today's market" is just hand-waving. A Graham analysis such as "net net" (valuing stocks by their current tangible assets net of all liabilities) is a quantitative analysis of accounting numbers audited by CPAs and offers a true margin of safety.
