工作中关于Hedge fund

本文介绍了对冲基金的复杂投资策略及其使用的Prime Brokerage服务。详细讲解了资金托管、交易执行、保证金制度、现金管理和客户报告等内容。

本文主要简单介绍下本人工作经历中关于对冲基金的业务:

 

Hedge Funds:Use wide range of complex and sophisticated Investment Strategies

  • Investment Vehicles
  • Big Bets
  • Wide range of assets
  • Specialise in sophisticated investment techniques

Prime Brokerage是为对冲基金提供各类服务的desk:



 

 

What is Custody(资金托管),主要是保护客户的资产:(cash,securities,bonds,commodities...)

Clearng...who owes money to whom? who now owns theses securities?(谁欠谁钱,谁拥有这些股票等 )

settlement...Transfer of ownership ,transfer of cash ,exchange for securities 所有权的转移

Asset Servcing including... Dividend payments(利率结算)Managing corporate actions.



 

Trade Execution(交易执行):

 

PB’s can execute trades on behalf of clients or other brokers, and earn a fee for doing so…

 

Execution means Broker or dealer who finalises and processes a trade on behalf of a customer by different types of execution – Trading floor, electroninc (market makers), orders being filled.

Order to the floor --NYSE still uses this method today

internalisation--Broker fills order from it's own inventory

Electronic communications network(ECN)-- Automatically Match Buy and Sell orders electronically to fill an order

Order to Market Makers--Used on exchanges such as the NASDAQ

 

What is Margin?

Margin= Protection from Risk

 

Risk = Exposure to things which could harm you

Risk Management = Finding and  measuring those risks so appropriate action can be taken

Margin = Is a way of identifying and protecting yourself from counterparty and market risk



 

Cash Management and Financing

Cash management and financing, traditionally performed by the Operations side of a Prime Brokerage.

Hedge Funds have LOTS of Cash,Manage client’s cash and provide them with returns on their cash holdings.

In it’s simplest form, financing is a floating line of credit, usually associated to an underlying benchmark like LIBOR.

 

Client Reporting

 

As a Prime Broker, we have an obligation to provide our Hedge Fund clients with daily reporting that is accurate and reflect the latest market data and client positions…

 

 

 

【无人机】基于改进粒子群算法的无人机路径规划研究[和遗传算法、粒子群算法进行比较](Matlab代码实现)内容概要:本文围绕基于改进粒子群算法的无人机路径规划展开研究,重点探讨了在复杂环境中利用改进粒子群算法(PSO)实现无人机三维路径规划的方法,并将其与遗传算法(GA)、标准粒子群算法等传统优化算法进行对比分析。研究内容涵盖路径规划的多目标优化、避障策略、航路点约束以及算法收敛性和寻优能力的评估,所有实验均通过Matlab代码实现,提供了完整的仿真验证流程。文章还提到了多种智能优化算法在无人机路径规划中的应用比较,突出了改进PSO在收敛速度和全局寻优方面的优势。; 适合人群:具备一定Matlab编程基础和优化算法知识的研究生、科研人员及从事无人机路径规划、智能优化算法研究的相关技术人员。; 使用场景及目标:①用于无人机在复杂地形或动态环境下的三维路径规划仿真研究;②比较不同智能优化算法(如PSO、GA、蚁群算法、RRT等)在路径规划中的性能差异;③为多目标优化问题提供算法选型和改进思路。; 阅读建议:建议读者结合文中提供的Matlab代码进行实践操作,重点关注算法的参数设置、适应度函数设计及路径约束处理方式,同时可参考文中提到的多种算法对比思路,拓展到其他智能优化算法的研究与改进中。
