The growth versus value battle rages on. Growth investors seek companies that offer strong earnings growth, and value investors look for stocks that appear to be undervalued. Value, notwithstanding its incredible oracles, has performed relatively poorly over the last decade, and may now be on the wrong side of rampant technological disruption, driven, in part by COVID-19.

Of course, the jury is still out on the economic recovery. Value has seen some rotation into cyclicals, as is typically the case at the beginning of a recovery. …

Quantitative analysis has long sought to encroach on this territory with its rock-star math. But quant trading models and strategies that mostly rely on pattern recognition can run afoul of the cardinal sin of overfitting. They may also fail to adequately control for political, structural, and behavioural idiosyncrasies.

This short article will share insights collected from some leading data scientists in finance to help you improve your productivity and the accuracy of your machine learning modelling.

1. Asking the right questions of data in finance

According to the Economist and industry leaders such as Andrew Ng and Google’s CEO Sundar Pichai, data has become the new oil and machine learning the new electricity.

This has encouraged organizations to launch their own data science initiatives in order to make sense of the treasure trove of data they’ve built over the years and apply it in profitable ways. However, in many cases, there is so much data that organisations struggle to assess whether they are holding oil or mud.

This short article will outline how to solve three core data problems and turn your organization into a value-generating data refinery. …
