英文摘要:
Market makers provide liquidity to other market participants: they propose prices at which they stand ready to buy and sell a wide variety of assets. They face a complex optimization problem with both static and dynamic components. They need indeed to propose bid and offer/ask prices in an optimal way for making money out of the difference between these two prices (their bid-ask spread). Since they seldom buy and sell simultaneously, and therefore hold long and/or short inventories, they also need to mitigate the risk associated with price changes, and subsequently skew their quotes dynamically. In this paper, (i) we propose a general modeling framework which generalizes (and reconciles) the various modeling approaches proposed in the literature since the publication of the seminal paper \"High-frequency trading in a limit order book\" by Avellaneda and Stoikov, (ii) we prove new general results on the existence and the characterization of optimal market making strategies, (iii) we obtain new closed-form approximations for the optimal quotes, (iv) we extend the modeling framework to the case of multi-asset market making and we obtain general closed-form approximations for the optimal quotes of a multi-asset market maker, and (v) we show how the model can be used in practice in the specific (and original) case of two credit indices.

中文摘要:
做市商为其他市场参与者提供流动性:他们提出价格,准备好买卖各种各样的资产。他们面临着一个复杂的优化问题,包括静态和动态组件。他们确实需要以最佳方式提出出价和出价/要价,以便从这两个价格之间的差异(他们的买卖价差)中赚钱。由于它们很少同时买入和卖出,因此持有多头和/或空头库存,因此它们还需要降低与价格变化相关的风险,并随后动态调整报价。在本文中,(i)我们提出了一个通用的建模框架,该框架概括(并协调)自Avellanda和Stoikov发表开创性论文《限价指令书中的高频交易》以来文献中提出的各种建模方法,(ii)我们证明了关于最优做市策略的存在性和特征的新的一般结果,(iii)我们获得了最优报价的新的封闭形式近似值,(iv)我们将建模框架扩展到多资产做市商的情况,并获得了多资产做市商最优报价的一般封闭形式近似值,以及(v)我们展示了如何在两个信用指数的具体(和原始)情况下实际使用该模型。
