Abstract: Motivated by the puzzling null impact of high‐frequency‐based jumps on future volatility, this paper exploits the rich information content in high‐frequency jump intensity with a mark structure under the heterogeneous autoregressive framework. Our proposed model shows that harnessing jump intensity information from the marked Hawkes process leads to significantly superior in‐sample fit and out‐of‐sample forecasting accuracy. In addition to statistical significance evidence, we also illustrate the economic significance in terms of trading efficiency. Our findings hold for a variety of competing models and under different market conditions, underlying the robustness of our results.
