[podcast] Creating the ultimate algorithm: How Numerai gets experts to build successful trading strategies

We’ve spent the past couple of weeks of this show talking to leading early-stage investors in financial technologies — guys like Charles Moldow of Foundation Capital and Caribou Honig of QED Investors.

These are the same guys that have invested in some of the biggest names in the financial technology space. Companies like Lending Club, Credit Karma, Motif Investing, OnDeck Capital, Prosper, and Zopa. What makes many of these companies different from their incumbent competitors is that they’re bringing technology solutions to financial problems.

That’s not to say incumbent financial institutions don’t use technology — they certainly do, a whole lot of it. It’s just that this generation of fintech company is exactly that fin – tech: they’re technology companies at their core and their solutions to financial problems — whether lending to people without credit history or remitting money more cheaply and quicker across global banking borders. They’re technological in nature.

Some of the most interesting things we’ll see in the future is machine learning applied to the stock market. We know human beings’ biases when it comes to investing and even the world’s best investors fall prey to our own shortcomings, our own humanity. It’s entirely possible machines can do it better. Our next guest, Richard Craib, is working on a machine learning solution to the stock market much in the same way Netflix turned to top external algorithm developers to improve its own recommendation engine — by offering prizes.

Richard’s company, Numerai is an amazingly ambitious undertaking. He’s offering top investing systems developers cash prizes in return for using his firm’s encrypted data set to build alpha-producing strategies. Sitting on top of it all is Numerai with its own big data solution that’s investing its own nostro account, trying to optimize allocating capital between strategies. It’s a black box of black boxes but crowdsourced from some of the world’s smartest data scientists.

As I talked with Richard, I kept thinking to myself, what does this spell for the future of investing? People like Warren Buffett and Peter Lynch — two of my favorite all-time investors — seem so antiquated when you start thinking about AI’s potential to participate in investing. Will future episodes on CNBC profile — not today’s celebrity cowboy stock picker — but tomorrow’s PhD-touting data scientist who builds software for a living? Interesting.
