We evaluate the impact of complexity and information content of 10-K filings on uncertainty dynamics following the filings. We have three main findings. First, the option implied volatility on average increases in the first four weeks after the filings, followed by a net decrease in the subsequent six weeks. Second, this hump-shaped volatility dynamics is more pronounced for firms with larger 10-K file sizes. Third, we provide a novel decomposition of 10-K file size based on the individual sections' disclosure amount and topic analysis, and find that the discussions on topics in the Risk Factors section mainly capture the complexity aspect whereas the discussions on topics in the Managerial Discussion and Analysis (MD\&A) section mainly capture the information content aspect of the 10-K filings. Our findings highlight the importance of the timing for understanding the opposing effects of complexity and information content on asset prices.
