most authoritative work on how to value financial assets.
"Williams combined original theoretical concepts with enlightening and
entertaining commentary based on his own experiences in the
rough-and-tumble world of investment."
Williams' discovery was to project an estimate that offers intrinsic
value and it is called the 'Dividend Discount Model' which is still used
today by professional investors on the institutional side of markets.
