Beskrivelse
The Sharpe ratio is the most widely used metric for comparing the
performance of financial assets. The Markowitz portfolio is the portfolio with
the highest Sharpe ratio. The Sharpe Ratio: Statistics and Applications
examines the statistical propertiesof the Sharpe ratio and Markowitz portfolio,
both under the simplifying assumption of Gaussian returns and asymptotically.
Connections are drawn between the financial measures and classical statistics including
Student''s t, Hotelling''s T^2, and the Hotelling-Lawley trace.
The robustness of these statistics to heteroskedasticity, autocorrelation, fat tails,
and skew of returns are considered. The construction of portfolios to maximize
the Sharpe is expanded from the usual static unconditional model to include
subspace constraints, heding out assets, and the use of conditioning information on
both expected returns and risk. {book title} is the most comprehensive
treatment of the statistical properties of the Sharpe ratio and Markowitz
portfolio ever published.
Features:
* Material on single asset problems, market timing,
unconditional and conditional portfolio problems, hedged portfolios.
* Inference via both Frequentist and Bayesian paradigms.
*A comprehensive treatment of overoptimism and overfitting of trading
strategies.
*Advice on backtesting strategies.
*Dozens of examples and hundreds of exercises for self study.
This book is an essential reference for
the practicing quant strategist and the researcher alike,
and an invaluable textbook for the student.
