资源简介:
We introduce artificial intelligence pricing theory (AIPT). In contrast with the APTs foundational assumption of a low dimensional factor structure in returns, the AIPT conjectures that returns are driven by a large number of factors. We first verify this conjecture empirically and show that complex
我们提出人工智能定价理论(Artificial Intelligence Pricing Theory, AIPT)。与套利定价理论(Arbitrage Pricing Theory, APT)关于收益存在低维因子结构的基本假设不同,人工智能定价理论(AIPT)推测收益由大量因子驱动。我们首先通过实证验证这一推测,并证明复杂
