Wine Investment For Portfolio Diversification by Mahesh Kumar. A London based, chartered accountant and financial professional develops the Fine Wine Index and documents how investment in fine wines over past 20 years equal or exceed the return from stocks and bonds. Based on the Nobel Prize winning portfolio theory of Harvey Markowitz, the author provides a mean-variance model with expected return, standard deviations (risks) and correlations between asset returns. Since portfolios including Fine Wines have higher Sharpe ratios than stocks and bonds only, they have a higher expected rate of return per unit of risk. Extensive data and charts document the performance for each investment for every 5 year period since 1983. The blue chip wines and vintages are discussed and strategies for reduction of risk by buying the right wines at the right time are recommended. Hardbound, 128 pp.
