三、主要内容:
Factors are time-varying. We propose a narrative-based forecasting approach using a large news corpus and machine learning algorithms to time factors and investigate their properties. Narrative-based forecasts perform well both in-sample and out-of sample, which leads to sizable economic gains. The predictability mainly comes from the cash flow news channel, containing information that relates to sentiment and future investment opportunities beyond traditional economic and financial aspects. Overall, we novelly approach factor timing with economic narratives.
