英文摘要:
We investigate the forecasting ability of the most commonly used benchmarks in financial economics. We approach the usual caveats of probabilistic forecasts studies -small samples, limited models and non-holistic validations- by performing a comprehensive comparison of 15 predictive schemes during a time period of over 21 years. All densities are evaluated in terms of their statistical consistency, local accuracy and forecasting errors. Using a new composite indicator, the Integrated Forecast Score (IFS), we show that risk-neutral densities outperform historical-based predictions in terms of information content. We find that the Variance Gamma model generates the highest out-of-sample likelihood of observed prices and the lowest predictive errors, whereas the ARCH-based GJR-FHS delivers the most consistent forecasts across the entire density range. In contrast, lognormal densities, the Heston model or the Breeden-Litzenberger formula yield biased predictions and are rejected in statistical tests.

中文摘要:
我们调查了金融经济学中最常用的基准的预测能力。我们通过在21年多的时间段内对15个预测方案进行综合比较,探讨概率预测研究的常见注意事项——小样本、有限模型和非整体验证。所有密度均根据其统计一致性、局部精度和预测误差进行评估。使用一个新的综合指标,综合预测分数(IFS),我们表明,风险中性密度在信息内容方面优于基于历史的预测。我们发现,方差伽马模型产生了观测价格的最高样本外可能性和最低的预测误差,而基于ARCH的GJR-FHS在整个密度范围内提供了最一致的预测。相反,对数正态密度、赫斯顿模型或布里登-利岑伯格公式产生了有偏差的预测,在统计测试中被拒绝。
