英文摘要:
Stochastic volatility models describe stock returns $r_t$ as driven by an unobserved process capturing the random dynamics of volatility $v_t$. The present paper quantifies how much information about volatility $v_t$ and future stock returns can be inferred from past returns in stochastic volatility models in terms of Shannon\'s mutual information.

中文摘要:
随机波动率模型将股票收益率$r\\t$描述为由捕捉波动率$v\\t$随机动态的未观察过程驱动的。本文根据香农的互信息,量化了随机波动率模型中,从过去的收益中可以推断出多少关于波动率v\\t$和未来股票收益的信息。
