Optimal Liquidation Strategies And Their Implications, Christopher Ting, Mitch Warachka, Yonggan Zhao Apr 2007

Optimal Liquidation Strategies And Their Implications, Christopher Ting, Mitch Warachka, Yonggan Zhao

Research Collection Lee Kong Chian School Of Business

This paper studies optimal liquidation when the selling price depends on the rate of liquidation, transaction time, volume, and the asset's intrinsic value. A generic closed-form solution for maximizing the discounted liquidation proceeds is derived. To obtain financial insights, three parametric specifications that proxy for increasingly realistic market conditions are examined. In our framework, maximizing liquidation proceeds and minimizing liquidity costs are equivalent. The optimal strategies imply more rapid liquidations in less liquid markets. We also show that volatility is stochastic when market liquidity is unpredictable.


Realized Daily Variance Of S&P500 Cash Index: A Revaluation Of Stylized Facts, Shirley J. Huang, Qianqiu Liu, Jun Yu Mar 2007

Realized Daily Variance Of S&P500 Cash Index: A Revaluation Of Stylized Facts, Shirley J. Huang, Qianqiu Liu, Jun Yu

Research Collection Lee Kong Chian School Of Business

In this paper, the realized daily variance is obtained from intraday transaction prices of the S&P 500 cash index over the period from January 1993 to December 2004. When constructing realized daily variance, market microstructure noise is taken into account using a technique proposed by Zhang, Mykland, and Ait-Sahalia (2005). The time series properties of realized daily variance are compared with those of variance estimates obtained from parametric GARCH and stochastic volatility models. Unconditional and dynamic properties concerning the realized daily variance are examined, the relationship between realized variance and returns is investigated, and the stylized facts concerning realized daily …
