Optimal Portfolio Liquidation with Distress Risk
We analyze the problem of an investor who needs to unwind a portfolio in the face of recurring and uncertain liquidity needs, with a model that accounts for both permanent and temporary price impact of trading. We first show that a risk-neutral investor who myopically deleverages his position to meet an immediate need for cash always prefers to sell more liquid assets. If the investor faces the...
متن کاملOptimal Portfolio Liquidation with Execution Cost and Risk
We study the optimal portfolio liquidation problem over a finite horizon in a limit order book with bid-ask spread and temporary market price impact penalizing speedy execution trades. We use a continuous-time modeling framework, but in contrast with previous related papers (see e.g. [28] and [29]), we do not assume continuous-time trading strategies. We consider instead real trading that occur...
متن کاملOptimal Portfolio Liquidation with Limit Orders
This paper addresses the optimal scheduling of the liquidation of a portfolio using a new angle. Instead of focusing only on the scheduling aspect like Almgren and Chriss in [2], or only on the liquidity-consuming orders like Obizhaeva and Wang in [31], we link the optimal trade-schedule to the price of the limit orders that have to be sent to the limit order book to optimally liquidate a portf...
متن کاملOptimal Liquidation Strategies Regularize Portfolio Selection
We consider the problem of portfolio optimization in the presence of market impact, and derive optimal liquidation strategies. We discuss in detail the problem of finding the optimal portfolio under Expected Shortfall (ES) in the case of linear market impact. We show that, once market impact is taken into account, a regularized version of the usual optimization problem naturally emerges. We cha...
متن کاملLiquidation Risk
Turmoil in financial markets is often accompanied by a significant decrease in market liquidity. Here, we investigate how such key risk measures as likelihood of insolvency, value at risk, and expected tail loss respond to bid– ask spreads that are likely to widen just when positions must be liquidated to maintain capital ratios. Our results show that this sort of illiquidity causes significant...
