This book is still in print sixty years after it was written, despite never having been updated or revised. That testifies to its classic status, in a field, financial analysis, which generally changes rapidly.
The author defines the “Investment Value” of a stock to be the net present value of all its future dividends. This definition provides a measure of intrinsic value which is independent of stock market prices, enabling the investor to assess whether the current market price is high or low compared with the Investment Value of the stock.
