Outline of the talk

  • Generational shift in asset management due to AI

  • How the Chief Investment Office can use AI in their workflow.
    (reference paper on this)

  • What do we need to build to implement AI in an organization(teams, workflows, architecture).

Workflow of institutional investing today

Pain points of institutional investors

The need for

  • Lower fees / costs

  • Greater transparency

A Machine Learning approach to strategy allocation

It turns out that allocating to investment strategies is very similar to recommender systems

Problem: Given a set of strategies one could allocate to, how much to allocate to each

  • Figure out what is similar between the strategies.
     
  • Figure out similarities between the days or periods you are using to backtest them.
     
  • Figure out the easiest prediction problem you can solve that will get your job done.

 

Use a matrix factorization approach to learn which strategies are similar and which dates are similar

This is very similar to the movie recommendation problem

Visualization of matrix factorization based collaborative filtering

We can extend the matrix factorization approach to include predictable market features like volatility and GDP growth

The secret sauce?

Unsupervised learning

"Unsupervised learning had a catalytic effect in reviving interest in deep learning, but has since been overshadowed by the successes of purely supervised learning. Although we have not focused on it in this Review, we expect unsupervised learning to become far more important in the longer term." - Geoffrey Hinton et. al., Nature, Deep Learning

- Investment strategies that learn by themselves (article)

How to implement A.I. within an investment company

An asset management firm needs to look like a tech company now

Infrastructure is key to ML

Investing with a trustworthy tool

"security analysis may begin--modestly, but hopefully--to refer to itself as a scientific discipline "

 

Imagining investing with a "trustworthy tool" and not experts!

- Benjamin Graham

Towards a science of security analysis published 1952

Key Takeaways

Asset management, a $160 trillion dollar industry is yet to be affected by A.I.

 

Time is ripe for the move to machine learning methods in institutional investing
(1) need to reduce costs
(2) find other sources of returns and
(3) use of systematic processes

 

You can make it happen!

Using unsupervised learning in the cost function

Using unsupervised learning in the cost function

Other pain points of institutional investors

I. Aversion to losing

It is not always just about higher returns.

Utility function is not uniformly distributed.

Utility function is not the same.

II. Anchoring around a sustainability rate

Most pension funds have a nominal target yield.

 

Not meeting the target yield is a big deal compared to outperformance

III. Capacity:

Investments that have scale and capacity  to get in and to get out

 

IV. Should work with illiquid assets:

Illiquid investments are a part of everyone's portfolio.

One cannot look at liquid investments without considering the illiquid assets that are a part of the portfolio already.

Asset Allocation >> Security Selection

“By choosing to place asset allocation at the center of the investment process, investors ground the decision-making framework on the stable foundation of long-term policy actions.

 

Focus on asset allocation relegates market timing and security selection decisions to the background, reducing the degree to which investment results depend on mercurial, unreliable factors.

 

Selecting the asset classes for a portfolio constitutes a critically important set of decisions, contributing in large measure to a portfolio’s success or failure. Identifying appropriate asset classes requires focus on functional characteristics, considering potential to deliver returns and to mitigate portfolio risk. Commitment to an equity bias enhances returns, while pursuit of diversification reduces risks. Thoughtful, deliberate focus on asset allocation dominates the agenda of long-term investors.”
 

– David Swensen

Goals of asset allocation:

(a) Target constant risk in the portfolio.

 

(b) Optimize portfolio for the specified utility function.

 

(c) Constrain any studies to a specified, systematic risk management threshold.

Using recommender systems in the Chief Investment Office

By Gaurav Chakravorty

Using recommender systems in the Chief Investment Office

Gaurav Chakravorty explains how recommender systems can be utilized for investment management and details how AI and deep learning are used in trading today. Gaurav begins by diving into chief investment offices, which are growing their in-house machine learning teams to fine-tune their allocation, using both traditional and alternative strategies. Gaurav shares a novel approach to deciding asset and strategy allocations, inspired by research in recommender systems. Gaurav then explores the application of deep learning in trading, discussing useful techniques for AI-driven asset managers as well as the blind alleys they’ve gone down. With these cases as context, Gaurav addresses some of the technical and operational aspects of AI, such as key bottlenecks in training and inference, the software frameworks and hardware platforms that are most useful for those workloads, deployments, the scaling challenges, and the key drivers of the cost.
