The Knapsack problem implementation in R

16.October 2020

Our own research paper ESG Scores and Price Momentum Are More Than Compatible utilized the Knapsack problem to make the ESG strategies more profitable or Momentum strategies significantly less risky. The implementation of the Knapsack problem was created in R, using slightly modified Simulated annealing optimization algorithm. Recently, we have been asked about our implementation and the code. The code is commented and probably could be implemented more efficiently (in R or in another programming language). For example, R is more efficient with matrices, but the code would not be that “straightforward”. Lastly, the most important tuning parameter is the temperature decrease (the probability of accepting a new solution is falling with the rising number of iterations).

Quant’s Look on ESG Investing Strategies

13.December 2019

ESG Investing (sometimes called Socially Responsible Investing) is becoming a current trend, and its proponents characterize it as a modern, sustainable, and responsible way of investing.

How are ESG scores measured? What are the common problems in ESG data? Are there any systematic ESG factor strategies that offer outperformance? These are some of the areas we wanted to explore, and we invite you on this journey with us …

Lexically Diverse Hedge Funds Outperform

24.October 2019

Do you want to have an outperforming hedge fund? Then write a description of your investment strategy more creatively, clearly and use more synonyms… Of course, I am just kidding. However, a recent academic study written by Joenväärä, Karppinen, Teo, and Tiu shows that text sophistication can be used to find skilled hedge fund managers. Lexical diversity is the propensity of the writer to use multiple synonyms rather than repeated words. Skilled and, therefore, cognitively gifted managers are more likely to use rich vocabulary when writing their strategy descriptions. Therefore, if you feel that your favorite manager composes clear and captivating texts, maybe he is skilled also in his primary role – investment management …
