Mathematical Models of Price Impact and Optimal Portfolio Management in Illiquid Markets
.
Andreev N. A.
The problem of optimal portfolio liquidation under transaction costs has been widely researched recently, thus producing several approaches to problem formulation and solving. Obtained results can be used for decision making during portfolio selection or automatic trading at high-frequency electronic markets. This work gives a review of modern studies in this field, comparing models and tracking their evolution. The paper also presents results of applying the most recent findings in this field to real MICEX shares high-frequency data and gives an interpretation of the results.

I study the sequential entry of intermediaries into an illiquid market. As intermediaries trade with rational counterparts, market depth affects and is affected by the possibility of entry. This feedback loop between entry and depth gives incumbent intermediaries more incentives to deter entrants, creating endogenous barriers to entry. Further, whether entry occurs or not in ...

I study the price/quantity effects of anticipated supply or demand shocks in a model of strategic trading, where imperfectly competitive traders share risk with price-takers. When there are at least two traders, anticipated shocks lead to the V-shaped pattern observed empirically: prices drift away from fundamentals before the shock, and slowly revert afterwards. How traders ...

I study how (VaR-based) financial constraints affect liquidity and welfare under different structures of the arbitrage industry. When capital is spread across numerous competitive arbitrageurs, financial constraints may impair their ability to provide liquidity, lowering other investors’ welfare. However, when capital is concentrated among arbitrageurs with market power, introducing constraints can make everyone better off ...

There are many different models for estimation of a yield curve from bond market quotes. These models are well suited for developed markets with high liquidity level and market data readily available. However, this is not always the case for developing markets that are characterized by infrequent trading, heterogeneous liquidity and frequent missing data.
In this ...

This paper studies the form of the instantaneous impact cost function in a financial market with transaction costs via an axiomatic approach. We show that several kinds of convexity of the cost function are equivalent to the corresponding properties of the price impact functions. The results clarify the implicit assumptions made when selecting a particular ...

Доклад посвящен приложению гарантированного подхода, предложенного Смирновым С.Н. [1],[2], к задаче управления портфелем финансовых инструментов на низколиквидном рынке с учетом модельной ошибки. Рассматривается игровая постановка в дискретном времени на конечном горизонте, в рамках которой инвестор максимизирует ожидаемое вознаграждение от портфеля (робастный эквивалент Сэвиджа) в конце стратегии. Оптимальная стратегия находится в неявном виде как решение соответствующего ...

We present a robust dynamic programming approach to the general portfolio selection problem in the presence of transaction costs and trading limits. We formulate the problem as a dynamic infinite game against nature and obtain the corresponding Bellman-Isaacs equation. Under~several additional assumptions, we get an alternative form of the equation, which is more feasible for ...

Управление портфелем ценных бумаг, для целей инвестирования или хеджирования, относится к классическим задачам финансовой математики, которые допускают различные постановки, обычно использующие стохастическое динамическое программирование, где управляемым объектом является структура портфеля, а рынок описывается некоторым стохастическим процессом.
Доклад посвящен альтернативе общепринятого стохастического подхода, - за основу берется неопределенность поведения рынка в будущем, а динамика рынка описывается одним ...

We study the boundedness properties of the value function for a general worst-case scenario stochastic dynamic programming problem. For the portfolio selection problem,we present sufficient economically reasonable conditions for the finitness and uniform boundedness of the value function. The results can be used to decide if the problem is ill-posed and to correctly solve the ...

This paper proposes a procedure for dynamic optimization of an investment portfolio, consisting of stock market indices. SJC-copulas were used to assets statistical characteristics of assets. Copulas allow to measure interdependence between financial instruments, and to build an efficient investment portfolio. Since statistical characteristics of assets are changing with time, the structure of the portfolio ...

The last couple of decades have witnessed significant institutional and structural changes in financial sector within a worldwide trend toward consolidation. In the segment of organized trading stock exchanges merge and develop into large and diversified publicly traded companies. These processes are rather complicated in case of a transition economy like Russia. In December 2011 ...

Одним из наиболее значимых изменений в структуре финансового рынка за последние несколько лет является развитие высокочастотной торговли (англ. High Frequency Trading, HFT). Согласно экспертным оценкам, она отвечает за большую часть транзакций на финансовых рынках (например, более 77% транзакций на рынке Великобритании, по данным Tabb Group) и способна критически влиять на возникновение системных нестабильностей. Например, в ...
