In my first set of articles on machine learning, I investigated whether deep neural networks, when trained on financial ratios, could predict future stock prices. The conclusion I drew in the second article was that no, financial ratios didn’t predict future stock prices. This finding was consistent with other people’s observations that algorithm driven value investing hasn’t worked in the past decade or so.

But while value investing hasn’t worked, other relatively simple strategies have. Some of these strategies solely act on signals drawn from the behaviour of stock prices ...

In part 1 of this series, I explained how deep neural networks (DNN) can discern complex cause and effect relationships that traditional statistical models can’t. I had also set up the question we are trying to evaluate using DNNs: is there some combination of financial ratios that can predict individual stock performances over the next 12 months?

In this article, I continue where I left off and present some of the results. I will also discuss some possible explanations behind the results and explore some ideas for the future.

I mentioned ...

Machine learning is arguably the hottest topic in technology today. It’s what has enabled us to shoot videos of ourselves spewing rainbows, and it’s what will enable cars to drive themselves in the future.

As I’ve read more about the topic, I’ve begun to wonder if machine learning could be applied to investing. To deepen my knowledge, I’ve spent the last few months reading books on the subject and practicing on data sets.

Fortunately, my educational background has allowed me to pick up the topic more easily. Machine learning, at its ...
