当AI 正在图像分析, 文字分析等方面大有突破时, AI发展却在财经市埸上"衰退"了. 在经历2015 年的黄金期后, AI 再没有为对冲基金带来爆发性的收入, 并持续跑输美国股市.
Eurekahedge AI对冲基金指数跟踪12个AI对冲基金的代表，自2013年以来表现优于对冲基金同业，但仍未能超过标准普尔500指数。
但其实这也不能完全怪责AI, 在近年美国股市要获取Alpha 非常困难, 由于AI操作经常依赖短期交易, 要在每次交易上获取充分利润, 就难上加难了.
While AI has a strong momemtum in image processing as well as natural language processing this year, AI development is in "recession" in the financial market. After the peak in 2015, AI have yet brought another surprising return to their clients and kept losing to the market index.
Eurekahedge AI Hedge Fund Index, which tracks 12 hedge fund using machine learning, has outperformed hedge fund peers since 2013 but failed to beat the S&P 500 Index.
But this is not completely AI's fault. In recent years, Active investors find it extremely hard to seek Alpha in US stock market. Becuase short-term investment relies entirely on high-frequency trading or short term speculation, secure certain profit in every trade is literally impossible.
