| Tiivistelmä: | Diversification of investments was a well-established practice long before 1952. What was lacking prior to 1952, was an adequate theory of investment that covered the effects of diversification when risks are correlated, distinguished between efficient and inefficient portfolios, and analyzed risk-return trade-offs on the portfolio as a whole. This article traces the development of portfolio theory in the 50s and compares it with theory prior to 1950. |
