如果你是高频交易量化分析师/研究员,今年的年终奖可能很丰厚哦!

根据Selby的一项最新调查显示,从事高频交易\做市商(BS)的Quant对今年的奖金预期很高。其他领域的量化分析师就不那么乐观了。
根据数据显示,2020年7月,一些主要*电子做市商机构新发布的工作岗位数量比2月份增加了28% ,仅略低于1月份。
Virtu、Jump Trading、Hudson River、Citadel Securities、G-Research、Two Sigma、Tower Research、DRW Trading、Hudson River、Quantlab、IMC Trading、CTC Trading、Jane Street、Susquehanna International Group
尽管如此,进入做市商领域并不容易。因为很多公司在员工相对较少的情况下需要创造较高的收入和利润,他们雇佣的员工都是十分出色的技术人员。
Virtu Financial
我们就拿Virtu Financial来说。像Virtu这样的高频交易机构来说,2020年他们取得了创纪录的收入,业绩非常出色,其奖金预计能涨50% 。
Virtu Financial在第三季度表现仍高于历史平均水平,第三季度仍比前两年高出30-45%:
Virtu有着庞大的股票做市商业务,第二季度收入增长343%,达到4.76亿美元,固收的做市商业务收入增长176%,达到7800万美元,也还行:
其他一些数据:
Jane Street
2016年,纽约时报将Jane Street描述为:
Jane Street平均每天在全球范围内交易超过210亿美元的股票、债券和ETF,并在纽约、伦敦、阿姆斯特丹和香港设有办事处。
Jane Street的员工薪酬是一个迷。根据网媒未经证实的消息称,Jane Street在美国为实习生每月工资为$14.5K,外加每周$500在家工作的津贴,每月总计为$16.5k。
对于Jane Street相对junior的工作,你不一定需要懂金融或经济,但你需要知道如何编程。Jane Street的代码几乎全部使用OCAML,因为他们是函数式编程的拥护者,Jane Street从系统自动化到交易系统,从监控工具到代码研究,Jane Street使用OCaml编写所有其能写的东西。
OCaml
全称Objective Caml,是Caml编程语言的主要实现,由Xavier Leroy,Jérôme Vouillon,Damien Doligez,Didier Rémy及其他人于1996年创立。OCaml是开放原始码项目。此项目的管理和大部分维护工作交由INRIA。
由于caml的读音与camel一致,OCaml的吉祥物自然被定为骆驼,而以OCaml服务为主的软件也通常以骆驼的形象作为其LOGO。
OCaml将Caml语言在面向对象方面做了延展。Caml 是函数式编程语言,它的扩展语言还有基于微软.net平台的 f# (fsharp)语言。Caml 的代码大多可以在f#中使用。F#的开发工具有VS .net,Caml的代码也可使用。OCaml的开发工具包含交互式顶层解释器,字节码编译器,以及最优本地代码编译器。
OCaml有一个巨大并强悍的标准库,这使得她可以像Python或者Perl语言一样可以方便地开发各种应用程序,健壮的模块化与面向对象编程结构又使得她可以胜任大规模软件工程项目。
如果你想在Jane Street找到一份收入最高的工作,你需要有解决一些极难的脑筋急转弯。Jane Street因在面试时向其候选人提出具有挑战性的脑筋急转弯而闻名。公众号列出几个给各位Quant瞧瞧,看看你们能做出来否,祝你好运!
Puzzle1
Each of the grids below is incomplete. Place numbers in some of the empty cells so that in total each grid’s interior contains one 1, two 2’s, etc., up to seven 7’s. Furthermore, each row and column within each grid must contain exactly 4 numbers which sum to 20. Finally, the numbered cells must form a connected region, but every 2-by-2 subsquare in the completed grid must contain at least one empty cell.
Some numbers have been placed inside each grid. Additionally, some blue numbers have been placed outside of the grids. These blue numbers indicate the first value seen in the corresponding row or column when looking into the grid from that location.
Once each of the grids is complete, create a 7-by-7 grid by “adding” the four grids’ interiors together (as if they were 7-by-7 matrices). The answer to this month’s puzzle is the sum of the squares of the values in this final grid.

Puzzle2
A random line segment of length D is chosen on a plane marked with an infinite checkerboard grid (i.e., a unit side length square grid).  What length D maximizes the probability that the segment crosses exactly one line on the checkerboard grid, and what is this maximal probability?
答案:
The answer to this puzzle is that D = 1 and the resulting probability is 2/pi (or about .6366). 
Puzzle3
Call a “ring” of circles a collection of six circles of equal radius, say r, whose centers lie on the six vertices of a regular hexagon with side length 2r. This makes each circle tangent to its two neighbors, and we can call the center of the regular hexagon the “center” of the ring of circles. If we are given a circle C, what is the maximum proportion of the area of that circle we can cover with rings of circles entirely contained within C that all are mutually disjoint and share the same center?


When submitting an answer, you can either send in a closed-form solution, or your answer out to 6 decimal places.
答案
The answer when rounded to 6 decimal places is 0.783464.
Puzzle4
Two friends, Alter and Nate, have a conversation:
Alter: Nate, let’s play a game. I’ll pick an integer between 1 and 10 (inclusive), then you’ll pick an integer between 1 and 10 (inclusive), and then I’ll go again, then you’ll go again, and so on and so forth. We’ll keep adding our numbers together to make a running total. And whoever makes the running total be greater than or equal to 100 loses. You go first.


Nate: That’s not fair! Whenever I pick a number X, you’ll just pick 11-X, and then I’ll always get stuck with 99 and I’ll make the total go greater than 100.


Alter: Ok fine. New rule then, no one can pick a number that would make the sum of that number and the previous number equal to 11. You still go first. Now can we play?


Nate: Um… sure.
Who wins, and what is their strategy?
答案
Nate (the first player) can always win in this game, by starting with the number 3.After this first turn, Nate can force the running total to increment by units of 12.This could happen 2 different ways:
1、If Alter picks some number X between 2 and 10, Nate chooses 12-X
2、If Alter picks 1, Nate responds by picking 1 as well.  Now Alter cannot pick 10 (since this would force the sum of the previous two numbers to be 11), and must pick some other number Y.  Nate then picks 10-Y.
In this way, Nate can force Alter to choose numbers when the running total is equal to 3, 15, 27, 39, 51, 63, 75, 87, and 99.  At this point, Alter is forced to take the total to 100 or greater.
G-Research
说起G-Research,它更像是一个算法研究机构。这家总部位于伦敦的量化研究和技术公司,目前大概雇佣了800名员工。
G-Research在公众号眼里一直很神秘!
说起G-Research,公众号在这里也提一下当年发生在行业内的一段真实故事:
一个中国数学神童,一路学霸剑桥毕业,入职G-Research,不满400万人民币奖金辞职,然后身陷旷日持久的牢狱之灾。
彭博在18年写过一篇很长的文章,大家感兴趣可以看看。公众号觉得都是过去的事了,我们就不必纠结,也不必去评论是与非,一切向前看!
G-Research成立于2012年,由Ben Leadsom运营。Leadsom曾是巴克莱银行的银行家,但自2009年以来一直是Island Research的董事(G-Research是该有限责任合伙企业的一个组成部分)。根据Island Research最近提交的账目:
G-Research2019年的营业额为£289m,营业利润为£56m。
G-Research和Island Research的非合伙人级别员工受雇于一家名为Trenchant Employment Services的实体。2019年,该公司雇佣了753人,高于前一年的599人。2019年,热门岗位的人均薪酬为15.8万英镑。
G-Research有一种独特的文化。能够将学界的智力挑战与快节奏的商业环境结合完美结合。其不断改进文化,为员工提供了最好的教育环境,确保他们在整个职业生涯中都能在G-Research持续学习与发展。
G-Research的伦敦办公室有自己的演讲厅和活动场所,在那里,Hannah Fry、bo-shen Lo、Dermot Turing和《Surveillance Capitalism》一书的作者Shoshana Zuboff都给员工们做过讲座。
G-Research对量化新人的面试很严格。首先是量化金融能力测试,接着是HackeRank测试,然后是技术面试。
Hackerank在金融服务领域欢迎程度很高,高盛、摩根士丹利、美国银行、彭博、BNY Mellon和德意志银行都是他的客户,像Two Sigma这样的对冲基金也有使用。
好了,今天的推文就到这里,希望大家对Market Making有一个多元的了解。后续公众号会报道更多这样的内容!
