AI Hedge Fund Is Said to Liquidate After Less Than Two Years

The fledgling world of AI hedge funds is claiming one of its first casualties.

Sentient Investment Management is notifying investors of plans to liquidate the hedge fund it started in late 2016, according to people with knowledge of the situation. The fund managed less than $100 million and hasn’t made money this year after gaining 4% in 2017, one of the people said.

Sentient, based in San Francisco, used artificial intelligence techniques, including machine learning and so-called evolutionary algorithms, to trade stocks globally. It followed a market-neutral strategy in which bets on rising prices were matched by wagers on falling ones.

Sentient Investment Management grew out of Sentient Technologies Inc., an AI startup formed by Babak Hodjat and Antoine Blondeau. Before starting the hedge fund, they spent almost a decade developing an AI system capable of scouring billions of pieces of data, spotting trends, learning and trading stocks.

The firm’s team of technology-industry veterans was betting that software responsible for teaching computers to drive cars, beat the world’s best poker players and translate languages would give their fund an edge on Wall Street pros.

Sentient’s hedge fund deployed thousands of computers around the world, using algorithms to essentially create trillions of virtual traders, which it called “genes.” These genes were given hypothetical sums to trade in simulated situations created from historical data. The unsuccessful genes were discarded, while those that made money were spliced together with others. Thanks to increases in computing power, Sentient could squeeze 1,800 simulated trading days into a few minutes.

Technology giants including Google kicked off the AI boom several years ago by showing how a relatively new approach called deep learning could dramatically improve some software programs and services. Since then, hundreds of startups have sprouted, AI researchers have been snapped up in an expensive recruiting frenzy, and the technology has been applied to multiple fields, including finance, sales, customer service and self-driving cars.

There’s growing concern, however, among some AI researchers that the technology may not be reliable enough to tackle real-world challenges, such as autonomous driving or making investment decisions.

Filip Piekniewski, an expert in the AI field, recently predicted the advent of an “AI Winter,” a period of disillusionment and evaporating funding for such research. Breakthroughs appear to be slowing and those that do occur require ever-larger amounts of data and computer power, he said in a blog post earlier this year.

“Just because you have special tech and AI doesn’t mean you’re off to the races,” said Vasant Dhar, a professor at New York University who has run an AI-powered hedge fund for about a decade. “This tech is interesting but fraught with all kinds of risks.”
