My guest this week is Michael Reece, the chief data scientist for Neuberger Berman. The topic of our conversation is the use of data in the investment process, to help cultivate what is commonly referred to as an information edge.
I call the episode “Tim Cook’s Dashboard” because of an interesting question that Michael poses: if you armed the best apple analyst in the world with Tim Cook’s private business dashboard, what might that be worth? Effectively Michael’s goal is to recreate the equivalent of a company dashboard for many businesses, helping analysts understand the fundamental health and direction of companies a bit better than the market does, and in so doing create an actionable edge.
This is a daunting task, and you will hear why. It requires both a fundamental understanding of business and of data, statistics, and methods like machine learning. In our own work, we’ve found machine learning to be useless for predicting future stock prices, but extremely useful for other things, like extracting and classifying data.
This conversation can get wonky at times, but as listeners know that is the best kind of conversation, even if it requires a second, slower listen. I hope you enjoy this talk with Michael Reece. Afterwards, I highly recommend you invest the time to read a series of posts called Machine Learning for Humans, which I will link to in the show notes. It helps demystify the buzz words and explain how these new technologies are being used.
