Key Takeaways
- • Two Sigma co-founder David Siegel warned that current artificial intelligence lacks common sense and fundamental human-like reasoning capabilities, limiting its application across broader problem sets despite success in specific domains.
- • Two Sigma, a $37 billion quantitative hedge fund co-founded by Siegel in 2001, has achieved substantial outperformance—its Compass fund returned 12.6 percent year-to-date through August 2016, compared to 2.2 percent for the broader hedge fund industry.
- • Quantitative hedge funds as a category have outperformed traditional managers, gaining an average 4.5 percent annually over the past five years versus 3.5 percent for the average hedge fund, according to Hedge Fund Research Inc.'s quantitative directional index.
- • Machine learning adoption is accelerating across the industry, with prominent firms including Highbridge Capital Management, Bridgewater Associates, and Point72 Asset Management deploying algorithms to identify patterns in financial data and inform investment decisions.
- • Siegel acknowledged AI will solve specific, bounded problems but emphasized that achieving general human-level intelligence remains a distant objective, cautioning against overestimating the near-term transformative potential of current algorithmic systems.
Summary
David Siegel, co-founder and chief executive of Two Sigma Investments, delivered a cautionary message about artificial intelligence during remarks at the Bloomberg Markets Most Influential Summit on Wednesday, September 28, 2016. Despite Two Sigma's pioneering use of AI and machine learning to build a $37 billion hedge fund operation, Siegel emphasized that contemporary AI systems fundamentally lack common sense—a defining characteristic of human intelligence. "Artificial intelligence today doesn't have anything that resembles common sense, and common sense is a key feature of intelligence," Siegel, 55, stated. He further qualified the technology's limitations, noting that "AI today will solve certain problems but not everything," and that "the quest to create general human intelligence, that's probably a long way in the future."
Two Sigma stands as a marquee success story in quantitative investing. The New York-based firm, founded in 2001, has expanded dramatically over the past decade, growing from approximately $2.5 billion in assets to its current $37 billion under management. Performance metrics underscore the firm's competitive edge: Two Sigma's Compass fund returned 12.6 percent year-to-date through August 2016, substantially outpacing the 2.2 percent average return across the broader hedge fund industry for the same period, according to data compiled by Bloomberg.
The quantitative hedge fund sector more broadly has demonstrated sustained outperformance relative to traditional active management. Over the five-year period preceding this announcement, quantitative directional hedge funds generated average annual returns of 4.5 percent, compared to 3.5 percent for the average hedge fund, per Hedge Fund Research Inc.'s quantitative directional index. This performance differential reflects the structural advantages of systematic, data-driven investment methodologies.
Concurrent with Siegel's cautionary remarks on AI's limitations, machine learning adoption is accelerating throughout the alternative investment industry. Notable institutions including Highbridge Capital Management, Bridgewater Associates, and Point72 Asset Management are actively deploying machine-learning algorithms designed to identify patterns across large datasets of financial information to inform portfolio construction and trading decisions. These developments underscore growing recognition within institutional money management that algorithmic pattern recognition offers meaningful alpha generation potential, even as industry leaders like Siegel maintain realistic perspectives on current technological constraints.
