Long-Horizon Return Predictability from Realized Volatility in Pure-Jump Point Processes
纯跳点过程下基于已实现波动率的长期收益可预测性
We develop and justify methodology to consistently test for long-horizon return predictability based on realized variance. To accomplish this, we propose a parametric transaction-level model for the continuous-time log price process based on a pure jump point process. The model determines the returns and realized variance at any level of aggregation with properties shown to be consistent with the stylized facts in the empirical finance literature. Under our model, the…
