In this panel we will discuss how ML is changing Finance, and what will be the greatest disruptions in the near future. The rate of failure in quantitative finance is high, and particularly so in financial ML. However, that is a rare outcome, for reasons that will become apparent in this seminar. I will discuss the issues involved in the current generational transition, from old quant approaches to ML.

A key challenge in building an optimal portfolio is whether it will underperform out-of-sample. We will discuss procedures to improve out-of-sample performance. Pitfalls and common mistakes made by investment firms entering the ML field. A Heath Lecture at Stevens, on the research crisis and one possible solution. Why most discoveries in financial research are wrong, and what can we do about it. Recent breakthroughs in a post-Markowitz finance.

Symmetric measures of risk The main difference in the symmetric measures of risk, when compared with the asymmetric, is that returns above the pre-specified target are also included. The two symmetric risk metrics we consider are variance and MAD. Variance: the classical representation of variance deals with measuring the spread of the expected returns relative to the average expected portfolio return. In real life situations, to apply such models it is necessary to consider the trading requirements and other aspects of portfolio performance.

For instance, it is meaningful a not to have very small holdings, b to restrict the total number of holdings and c to take into consideration the roundlot of assets that can be bought or sold in a bunch. These requirements can be modelled as threshold constraints Section 1. The original perspective which is also a restrictive and narrow view of portfolio planning is that of asset management, namely buying, selling and rebalancing of assets.

This is formally known as portfolio dedication and is discussed in Section 1. The prices of fixed income securities are dependent on the term structure of interest rates and hence exposed to interest rate risk. Thus, measurement and modelling of such risks using duration and convexity and the corresponding restrictions also known as immunization are described in Section 1.

For discrete programming solution systems which do not support semi-continuous variables, such threshold restrictions may be specified using a binary variable and a pair of bounding restrictions. Imposing constraints that restrict stock holdings to integer multiples of specified roundlots increases the complexity of the model yet further. A review of portfolio planning: models and systems 19 The reformulation of model QP1 with buy-in thresholds is set out below.

By counting the binary variables introduced in model BUY-IN we can construct the cardinality constraint which limits the portfolio to a fixed number of assets k. It may be worthwhile to point out that buy-in thresholds and cardinality constraints are implicitly linked. Each block, or roundlot, can be described as a cash value or a number of stocks.

For each asset i , a block is defined as a 20 Advances in Portfolio Construction and Implementation fraction fi of the total portfolio wealth.
