Meet our authors:

bquanttrading – I’ve decided to take some time out of the markets after 8 years. Five of those years  was spent on an exotics options trading desk at a bank and the other 3 years on the buy side on a global macro trading desk. While I’m out of the market for a little while  decided to post some excel based modelling methods that are easy to implement and at the same time help with market analytics.

asmquant – I was one of the original members of a start-up macro hedge fund as a quant analyst/risk quant. I built trading analytic tools/models, risk management infrastructure and related risk models. I eventually founded a consulting company specialized in providing quantitative tools and models to hedge funds.
My main research interest is in risk modelling, and decided to share some interesting techniques in this blog.

We would like to ask the readers for a big favour.  Please do not email us asking for any files.  We have shared as much material as we are willing to share.  We believe all the details needed to implement the models we discuss are included in the post.

  1. Hi BM,

    I’ve been following your blog very closely since inception and have learn’t a ton in the process, so I must thank you for the incredible insight you have provided.

    Would it be possible for you to msg me via the email provided? I was hoping we could chat to learn more about your background, trading philosophy and discuss markets.

    I happen to have a background that is a bit similar to yours – from Tdot, self-taught (amateur) quant, and was previously at a macro fund down south. I feel we’re on the same wavelength and I definitely look forward to connecting.



      1. Thanks!

        P.S. It’s a pity that you are not attaching full samples of code or Excel worksheets. It would save some of us hundreds of studying hours:) In any case, thank you for sharing your experience, it’s very valuable!


      2. i think the best way to learn is to try it yourself. besides, its likely you will find a bug here and there if you try to replicate the work on your own. also, there is no way to upload macro enabled files on wordpress. there may be a hack but i couldnt be bothered to look it up.


  2. great blog! I really appreciate all the effort and complete posts. Quick question, for someone with a CFA but not an advanced mathematics or CS degree, what are your thoughts on the best way to get up to speed in the quant world. Any coursera courses/books strike you as really good. I did Ng’s Machine Learning but couldnt keep up with both the math and programming. any thoughts would be appreciated. I see your platform of choice is excel and R


    1. hi abc, I thought A Ng’s coursera MOOC was great. Its probably important to refresh on the math. Just grab a couple used textbooks and use them as ref when plowing through the course. Intro to stat learning https://lagunita.stanford.edu/courses/HumanitiesSciences/StatLearning/Winter2016/about is very good. I also liked Carol Alexander’s Market Risk Analysis series http://ca.wiley.com/WileyCDA/WileyTitle/productCd-0470998008.html. If you want to learn excel/vba the best way i think is to just pick a project and work through it and use the internet. I would strongly recommend http://ca.wiley.com/WileyCDA/WileyTitle/productCd-0471387347.html and http://shop.oreilly.com/product/9780596008796.do. Theres enough here for you to see what you find interesting and what your strengths are and continue from there.



      1. hey bqquant, thanks for the tips, I can now say I am a huge fan of R, partially thanks to you. even if I cant understand how you wanna do a lot of the math stuff still in Excel.

        I just had a quick question i was hoping you might have had experience with or have so simple ideas. I am looking to make a score of various economic stats, like Housing, Retail Sales, Employment. large categories with a few different stats to consider. I would like to make a simple score say on a scale of 1 -10 or -10, +10. Any thoughts, ideas or research you may have seen.

        I was thinking of doing a composite some score based on the distance of some moving average and a score referring to the short term trend./ monthly change


  3. Hi, Am trying the codes on logistic regression with my set of data but am getting ‘#value’ error. what could be the problem. Any help please


  4. I have spent some time working through your three part tutorial on SVM, and I have learned a lot. Thank you. However, in trying to apply it, i need to extend it to multiple input dimensions, not just xi and x2 but x1, x2, x3, x4 etc, Although I think I now understand how to get the alphas for such cases, I cannot work out how to define a formula for the multi-dimensional hyperplane, or place a new test case into a formula to obtain its x1 value knowing x2,x3,x4 and alpha etc. I think it would be great if you could post a part four to your SVM tutorials addressing multi-dimensional input case. Or, alternatively, simple explain what I am failing to grasp about multi-dimensional cases.


  5. Hi bQuant,
    Thanks for a great series on SVM. I have one question. In the excel workbook svm_kernel_calcs_example, tab = Implicit Feature Mapping (Kernel) the solver determines the Alphas (H6:H34) and the value for coefficient b (R5). Q. how would you use these solved values to predict a new value, say X1 = 0 and X2 = 0.5 ?


  6. Recently discovered this treasure trove of a resource. Firstly, my genuine and sincere thanks for sharing these incredibly useful insights and explorations.

    With the vantage point of your experience and hindsight, I’m curious to hear your thoughts as to how successful (PnL-wise) and applicable these approaches are when married with a discretionary macro mandate (as opposed to purely systematic). I suspect an unspoken postulate that runs through these posts is that they don’t really ‘work’ (again, PnL-wise) on a ‘purely’ systematic basis (please do let me know if you disagree.) I’m curious as to how complementary, applicable and useful you found these methods when used as part of a quantitatively informed discretionary heuristic.

    Also curious as to whether you’ve dabbled in Python, given a lot of these methods port quite nicely with it.

    Would be more than happy to take this discussion ‘offline’ via DM, email or twitter.

    Best –


  7. re: your write up on PCA, you suggest using PC3 as the hedge ratio, i’ve read elsewhere that people try to hedge out PC1 and PC2, s.t. their hedge ratios are the product of PC1*PC2. It turns out that PC1*PC2 ~ PC3 – i was wondering if you had any insight or thoughts on that relationship and the two approaches.

    I was thinking that since Vector multiplication results in a Vector that is Orthogonal to both and the idea behind PCA is to calculate orthogonal vectors in descending significance that it makes sense that PC3 would be ~ PC1*PC2.
